Hey Guys, Just getting into reloading.. What powder have you been using and why.. Are there powders you prefer for accuracy? thanks

45 grains of Reloader 15 w/ 175SMK's.
308's aren't real picky about powders, lots of powders will give decent results. For me IMR 4895, 4064 give tight groups. Varget and H4895 have been good too in my rifle. I shoot mostly 168s at 100 to 200 yds. You can't go wrong with these. J-cats load is promising too. What ever you choose work your way up as each rifle is differant.

Good for a wide range of bullet makes.

I can use it in all 3 of my rifles.. .222/.243/.308

I use 41.5 grains of IMR 4064, Sierra 168 grain MK bullet, either Federal match or Wolf LR primer, once fired Federal or LC brass. I shot today at the range and I shot 94/100 standing on a reduced target at 100 yards. Not a great score, but it will do for now.

Are you loading for a bolt rifle or a gas rifle? Gas rifles are more particular about the powder choice.....

The standard accuracy powders for .308Win
BLC2, W748, AA2495 (extruded), AA2520, TAC are also possibilities, but not nearly as popular since of most these are ball powders.

BLC2 and W-748

41.5 Gr H4895, BR2 primer, FGMM brass and 178 AMAXs give me 2670 FPS out of my rifle and decent groups out to 1000.

thanks for all the replies.. I am shooting out of a 20" barrelled bolt gun.. is there a powder more suited for a shorter barrel?

Theoretically the faster powders should give you the most velocity. I would try 4895, 748, Varget

Just came across this article:
In my 22" bolt gun the powders in order of preference for it are:
It does seem like that I can find an accurate load easier with the 4064 in a wider variety of guns and cartridges

I've had good fortune with VV N140 and either 168 gr. Sierra Matchkings or 167 gr. Lapua Scenars. Unfortunately, N140 has become quite scarce so I'm experimenting with N135, N540, IMR 4895, and IMR 4064. I have found that N135 is a very consistent shooter in my M14, but due to wind conditions at my local range, I haven't been able to chronograph the load yet (wind was blowing over my screens!). Quickload indicates that N135 might be a little bit fast for the .308, but if it shoots I'm going to use it!
Some of the standard powders to try:
Some of the standard bullets to try:
- 175SMK (or NCC)
- 168SMK (or NCC)
- 155Scenar (or new 155SMK model #2156)
Generally for 800ish or under, 168 seems to perform the best..... if you want to go above 800ish, then you'd need to go to 175 or 155S.
But it would be pretty difficult to get the MV requires to get over 800ish with a 20" barrel.... you would *generally* need 22"+ to get consistant results @ 1k.
With that said... your best bullet choice would be 168... SMK or NCC...
I shoot 168SMK out of my Israeli Mauser using Federal casings and 39.5 grs. of IMR 3031, Winchester LR primers. For an old bolt action rifle, it shoots surprisingly well with this load.

26" barrel 1:12 twist
42.5gr N140, 155gr scenar, Lapua brass, BR2, 2.795" COL.
Average speed 2,818, standard deviation 8.

Am I the only one using Acurate 2460??

Thanks for all the info.. I have been shooting Federal Gold Metal match 168's and they have been shooting great.. Best I have shot so far.. Well under moa.. So I will try to duplicate these.. Most of the shooting I will do will be under 500.. I might be getting into a .223 in the same gun so If you have any ideas for good loads there let them go.. I will be doing some experimenting like most of you have I am sure
Now Who has powder and primers in stock?

I've had good luck with IMR 4895...
Keep in mind, though, that accuracy can vary depending on the weight of the bullet. Most times, the most accurate powder for one bullet will not be the most accurate powder for a bullet of a different weight...
4895 is a good powder. So is 4064.
Also, some people don't like IMR 3031 but in all honesty, it a great powder for loading .308 with 168gr HPBT bullets. Don't rule out the 3031...
