Thank you very much, sir. I have about 60 federal brass and about 300 Lithuanian NATO brass, if I were to use those would I subtract 1.5grains?

I don't know.
You would have to size them and compare case volumes.
Leave a fired primer in one of each cases.
Size the cases without a decapping pin.
Weigh each case and note the empty weight.
Then fill each case with water to the top of the neck.
Now note the difference in weight between dry and wet for each case.
That's your case capacity in grains of water.
Post what you find.

Wilco. Lucky for me being a scientist, I have access to Micro-pipettes and syringes that can measure volumes very accurately. Now I'm just waiting on Midway to deliver my goods.

As you are filling the cases with a known volume of fluid, make sure you tap on the case to get all the air bubbles out.
People sometimes miss that and get erroneous measurements as a result.

cheap 308 Loads

You can find all pricing(rough) info on www.powdervalleyinc.com

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)

I have an Armalite AR10/20''barrel A2. A friend gave me 500 nato brass 7.62x51. I've been loading it for about .35 ea.
Then I discoverd the 7.62X54R CZ Steel case,corrosive berdain primed. I just wanted the bullets. Got a few and pulled them down. they are a 147gr. bullet with 46.2gr. of a stick powder..? Looked like a modern smokless powder. Ammo was made in 1986. So, I started with 42gr of this mystery powder and worked up to 43gr using the same bullets. Thats as far as I'm going. I'm about to run out of case space and they are as hot or a little hotter than federal factory loads. So now I'm loading my 7.62x51 "308" for about .21 ea.

If you have some federal brass, start with 46gr of Varget under a 155 SMK or 45gr under a 155 Scenar.
Work up from there.

I just went to Turners to start buying reloading ingredients and they dont have any Varget in stock. I was thinking of buying some Alliant Reloader 15 since I've seen quite a few loads using this powder. Is this powder recommended for a 20" barrel w/ 1:12 twist?

I personally use RL15. And RL15 is also the powder that is in LC M118LR.

Geez, after reading all this I feel like a real pedestrian with my 39.5 grs. of IMR 3031 (Winchester brass, WLR primers) pushing the 168 SMK.

what kind of results are you getting?

[Darklyte27]

Lapua Brass
175 SMK
FED210M
RL15 43.0gr
COAL: 2.85

~ 2700fps

Just shot some of my reloads this Sunday March 8th 2009.
100 yrds around 65*F
wind was variable from 5-8mph my estimate from right to left.
first 3 rds

WCC brass once fired
175 SMK
CCI #41 military primer *all I got until i get my BR and #400 this week*
Varget 42.5
COAL 2.83

next 4 shots
same as above except FC brass once fired
Should I now adjust the scope turrets as it is now as zero?

[Darklyte27]

Hey Hamster, what was your measurements with the Lith Brass? I got the same stuff..

Have you checked the bullet diameter? 7.62 Russian calibers are usually .311 rather than .308. It has to do with measuring to the lands rather than the groves. You may be resizing your bullets and doing God knows what to your barrel. Better check those bullets.

I am looking for a couple of large rifle magnum primers for testing purpose.

My favorite recipe for my Savage 10-FP HS Precision is:

-168 grain Sierra Matchking
-43.0 grains Hodgdon BL-C2
-Lapua .308 brass
-CCI bechrest Primers

What would be a good place to start reloading 175gf SMK with blc2. My Lyman reloading manual doesnt have BLC2 powder listed with the 175 SMK. It has 45 grain max listed in the 168 SMK chart. and randalls post, which has been very useful. thank you. shows 45.2 . Start right about 43gr and move up from there until i start seeing problems?

Hodgdon BL-C2 94.4 45.2 2.9

Hummmm! Maybe that's why they hold such a tight group. The only problem I have right now is the powder is really nasty! I can only get about 250 rounds out before I have to clean the chamber in my AR10. Thanks for the heads up.

[GunNut]

OH! the 7.62R's measure .310 when pulled. after a heavy taper crimp in nato brass they measure .308 and .310 behind the crimp.
