Do the math yourself. All depends on what you use, new Lapua brass is $0.50 each but you can get N-number of reloads out of it.

Roughly, $.35-.40 each if you have brass.
- premium bullet (eg 175SMK) ~$.25
- powder ~$.10
- primer ~$.02

Can get down below $.30 each if you use cheaper bullets (168Nosler)

wow! that's price shock from way back

Sierra 155 (2156) and Berger 175 VLD & Berger 155.5 Barrel is 30", 1:12", The only powders I'm interested in are IMR 4895, VARGET, V140 & V150

Thanks, SDJim

That's 12 simulations.
Narrow it down to 2 and I will run them.

[Rommel]

I am looking at working up loads for my AR-308 with a 20 inch barrel.

I have two powders, IMR 4895 and Varget. IMR is 38.2 grains and varget is 38.7 on starting loads supposedly to get ~ 2400 fps with a SMK 168gr. Primers are CCI and brass is Federal GMM, Privi and Winchester.

Should I start with those loads and work up? What percentage or grains should I bring my loads down from a standard bolt action load listed in the Sierra manual? TIA!

[SDJim]

Sorry Randal,
I was looking for tables like the ones at the beginning of this thread where it showed a whole list of powders. That's why I thought it would be 3 sims. I thought it would be easier if it wasn't listing all the powders. . . Anyway

30" Barrel, 1:12" twist, Bolt Gun, VARGET
SMK 155 (2156) becuase I'm curious to see if there is that much diffrence between the 2156 and the 2155, and the Berger 155.5

Thanks, SDJim

The 155.5 is a tad better than the 2156, and both are quite a bit better than the 2155. The further the target, the more dramatic the difference.

[Gnzrme]

Anybody using RE17...I switched from RE15 to that and I saw almost a 300FPS increase in velocity using that powder...Its larger than the RE15, so its going to fill up your case more....I am squeezing in 51.5grs into a Lapua match case...I get between 2800-2850 FPS...Trying to tweek the group size but its shooting about 3/4th's to 1/2 MOA at 100. Shooting this out of a PSS 700 with a 20" 11.25 Rock bbl....With RE15 I was averaging about 2600 FPS and I was trying to shoot at 1000 and when its cold, it goes down to about 2400-2500 so I was comming in subsonic at 1k

[phish]

What bullets are you using with RL17? I'm using 185 and 190 grain bullets with that powder and wouldn't even think of going over 48.5 grains. I've got some data in Excel, I'll forward it to you.

Sorry, forgot the bullet data....2156's...There was no data for use with the 2156's and Alliant recommended 50.00 grains as the load, so I loaded up 50 to 52.0 in 1/2 gr increments....52.00 was pretty hot, but didn't have any pressure signs although I would be interested to have a pressue gauge on the bbl....

You should try a 4895 with those bullets with a 20" barrel. RL17 needs a longer barrel to take advantage of its burn rate characteristics:

http://www.6mmbr.com/reloder17.html

I really would like a pressure trace system as well, but Salazar's data is a good starting point.

[Gnzrme]

Yeah, but try to find 4895....At one of our CA PRC shoots, somebody brought out some loads with 4895 and the had a SD and ES of 0! 5 shots were fired and I was there to witness it....

The SD was 0fps, the ES was like 3fps.

That was me.

There's been a lot of 4895 on the market recently I just picked up 2 8lbs kegs.

The load in question was:
155 Lapua Scenar
Lapua Brass
45.6 IMR 4895
Wolf LRM primer
Seated at 2.830

2850 FPS out of 24" bbl

[Hoop]

Does anyone have a recipe with accurate 2230 and a 168 grain bullet for .308? The reason I ask is someone gave me 16lbs of it and I'm trying to find a use for it.

[happy trigger]

Which set up do you think works best for 600 - 1000 yrd. shooting with this 24" barreled 308?

[Joe226]

I am new to reloading and will be purchasing my first shipment of bullets soon. I am shooting at no more than 200 yards for now. What would be the cheapest bullets I could use while still maintaining accuracy? I have a 26" barrel, 1:12, and will be using IMR 4895 for my loads. Would Speer 125 GR HP TNT's work or should I stay away from them and go for a heavier bullet?

46.5gr of varget under a Sierra 2156 at 2.800" in federal gold medal brass is a good one to try.

[Timberwolf]

Try 41.5 - 41.7 gr H4895 in FGMM case with BR-2s and either 175 SMK or 178 AMAX.

Also 47.0 gr IMR 4350 in FGMM case with 210M with 190 SMKs.

[TestPilot]

Following are some OCW/OBT loads from Dan Newberry's great site.

.308 Winchester using IMR 4895

155 grain bullet, 45.6 grains
168 grain bullet, 43.6 grains
175 grain bullet, 42.4 grains
178 grain bullet, 42.0 grains

.308 Winchester using Varget
155 grain bullet, 47.8 grains
168 grain bullet, 46.0 grains
175 grain bullet, 45.0 grains (an all around favorite)
180 grain bullet, 44.1 grains
200 grain bullet, low node 41.5 grains (10 twist barrel)
200 grain bullet, high node, 43.1 grains (10 twist barrel)

That's probably for the old 155 smk, not the new one.
That charge behind a 2156 will pop primers and maybe the ejector too!

[Lead-Thrower]

my favorite .308 load is:

175gr SMK
42.5gr Varget

I'm about to start reloading for a 16" .308 (M1A Socom). I made the mistake of already buying a few components before asking the questions (Shame on me). What receipe would you guys recomend for this gun? The little i bought was 1lb Varget, CCI LR primers, 168 HPBT Hornady Match bullets. If possible what's a good load using these for the M1A socom and what would the recommended components be for this gun? Also is there a significant difference between using cast bullets and jacketed at ranges up to 350 yards for the .308 of of such a short barrel? Oh and i'm not sure if it matters but according to a quick search it's got a 1/11" twist.

[Nessal]

I started to work up loads for another one of my newly acquired bolt guns and I was shooting .45moa accuracy at 100 yards all day one target after another. I was surprised because this was just my starting loads.

CCI 200 LR primers
Federal brass (fire formed and neck sized only, did not trim at all so length varied)
40grain IMR4895, yes 40 grains!
155grn Hornady Amax
.020" off the lands.

This is shot out of a Remmy short action with 26" Kreiger fluted barrel 1/12 twist in a AICS stock. I was surprised that I was shooting such small groups with my first loads that I think that I might just stick to that formula for short range work. Saves on powder!

My next loads will be with some Varget that I use for my .223 loads. I'll be doing more case work this time like turning the necks and trimming to a uniform length. My goal would be to hit 1/4 moa.

Try imr-xbr-8028 (42.3gr) and 155, 168 or 175 smk with a cci br lr primers seated to 2.8. They shot real well for me.

Does anyone have load data for Barnes 150 grain Triple Shock X bullets for .308 Winchester and/or 300WSM.

I’d love to find a Varget load for both to minimize the number of powders on my bench. I have a lb. of 7828ssc for the 300WSM, but most of the load data leans towards 180s or bigger.

These 150 Barnes load will be for lead free California deer zones. This is my first foray with Barnes bullets. I have learned they are often more sensitive in pressure than other bullets, and to work up loads in smaller increments. I almost always side toward the starting loads anyway; so that shouldn’t be a problem.

Any help or advice on Barnes bullets greatly appreciated.

I know this s a .308 thread, but I like having two rifles ready for deer season just in case. The 300WSM is a bit much for blacktails, but 150s might be good load for longe range and antelope.

Thanks in advance.

Hi All,

I have a G.A. Precision AR10 18" barrel on the way and I'm looking for load info so I can start to collect the right components.

GAP suggested 44gr Varget with the Sierra 175 SMK at 2.80" COAL.

I also have some 168gr FGMM to try.

What would be some other good bullet choices? Most of my shooting is 300 yds and in, but occasionally out to 600-800 yds.

I'm looking at maybe the 168 SMK and some other lighter weights.

How would the 155 Lapua Scenar do in a 18" barrel?

What would be a decent plinking bullet?

thanks in advance.

A 155gr bullet is fine for 500 yards. For that matter, so is a 135gr or a 210gr. What really matters is the velocity that you can push them at.

You might try the JBM ballistics calculator with your specific bullet and velocity to understand a bit more about how well your cartridge/rifle will operate out to 500 yards.

Federal Brass
CCI 200 primer
Sierra Match King 168gr HPBT
Varget: 45.5


I think it measured at .334 @100yds


.800 @ 200 yds

Remington 700 SPS Varmint (26" 1:12)

168gr SMK
44.2 gr Varget
CCI 200 Primer

Got me into the low .300" at 100 yrds

My sps tactical 20" doesn't really care what you feed it in terms of powder as long as the burn rate is in the appropriate range. Brass prep and neck tension seem to be the keys to good loads. FGMM gets really hard to resize and the primer pockets get kinda loose after 3 or 4 loadings. PMC brass is super hard in my IMHO plus the flash holes are never on center. I like stuff thans annealed from the factory.

I get sub moa groups with all of the following 168gr loads:

168 SMK loaded .020 off the lands (in my remington thats 2.885, yes 2.885)
168 AMAX loaded to 2.915
168 Hornady Match loaded to 2.900
LC or Federal Nato Brass and sometimes Federal GMM OR R.C. (Primer Pockets uniformed, Full length sized, trimmed to 2.004 - 2.006) Federal 210M, CCI BR2, W/W or just about any primer
39.5 gr IMR 3031
42.5 gr Varget
42 gr of RL-15
41.5 gr Bartlett surplus 4895, IMR 4895 or H4895
42.3 gr N140

I've tried them all, the most consistant have been Varget and Rl-15 but its definately a push, I don't shoot paper further out than about 200yds so the difference in any of these powders is neglegable to me. All listed loads are suggested loads from Zedikers or the Sierra Book developed years ago by guys who shoot alot more than I do so I figure why go hotter, why beat up the chamber or the brass. Another upside is The loads are moderate so you don't have to worry too much about some cases having smaller capacity (Lake City and PMC are the thickest as far as I can tell)...

My rifle is sensitive to seating depth, I used to load everything to 2.825 so it could go in the M1a mags too but now I keep that brass separate.
My best groups ever were under 1/2 when I ran out of match kings and finished a flat with some 168 Amax s. I loaded up about 25 before I realized that I forgot to reset the seating die and the OAL ended up at 2.915. when I compared the two different rounds I noticed that the Ogive on the hornady is way further back. I tried to chamber one and the bolt closed with 0 effort so I single fed those and gave it a shot. 5 shots, ONE RAGGED HOLE @ 100yds.

We used the RCBS precision mic to measure my chamber, using a 168 match king, I have to load 2.905 to touch the lands, amaxes have to be 2.935 and hornady match go 2.920.

I hope I'm not rambling on too much, sorry....

Berger 155.5 shot from a TRG-22 with 26" barrel

308 Lapula Palma brass
Varget 47 gr.
CCI 450 small rifle magnum primer
Berger 155.5 bullet
.075 off the lands
measures 2.170 from base of brass case to ogive

Chronograph showed average fps of 2872.4
Standard deviation is 10 fps

This load is for 600 to 800 yard range. It did not seem as accurate at I think it was 43gr of Varget which at 100 yard I could shoot .3 MOA and better. The hotter load is still excellent but If I was only going to shoot to 300 yards I go with lighter load.

If possible what's a good load using these for the M1A socom and what would the recommended components be for this gun? Also is there a significant difference between using cast bullets and jacketed at ranges up to 350 yards for the .308 of of such a short barrel? Oh and i'm not sure if it matters but according to a quick search it's got a 1/11" twist.

Varget is a little slow for an M14...2520 is the slowest burning powder I'd use.

Use jacketed bullets, OTM is OK. Save the boolits for your vintage rifles.

I've got a question for you guys. I'm new to loading so forgive me. How is it possible to share load information when loading for a bolt action , say 308 winchester? Isn't the OAL and COL different for each gun? And because of this , wouldnt that affect powder? Please enlighten me.

[Wreckreation]

I have 1700 rounds of 308 (1400 Belgium sealed in heavy rubber packs of 200 rnds. each and 300 of norinco in 20 rnds. boxes) and reloading gear all (not sold separately) for $1100. I can't find anything that resembles a classified add on the website so I'm posting this. Pictures and specifications via email. wreckreation@gmail.com
I'm located in San Francisco

its a good starting point. as you can take two of the same rifles and they will probably like something else from each other.

as for col/oal affecting powder, No

I can load my .308 to standard col/oal or a longer col/oal and use the same powder and charge weight for both.

[scfrogmansc]

Any one have a load data for 135GR SMK? overall length and charge with varget?

[Jicko]

Haven't tend to this thread for "quite" a while....

Let's talk about the new kid on the block:
Hornady 178 BTHP #30715

This is the bullet they use for their Superformance .308WIN 178BTHP ammo #8077, which is like 100fps faster than any other commercial ammo or even handload ammo.

Reloading book data (ultra conservative):
http://home.comcast.net/~johncollins...178gr_BRHP.pdf

Seemingly there are quite a lot of "good results" with the #8077 ammo, which proves that this bullet should fly and group well.

Now, it is time to develop some loads for it...... anyone of you got some good recipe?

Good'O RL15, Varget, 4895? Or some new ones like 2000MR, AR-Comp?
