Mil spec brass

Don't yell at me! I have one thing to ask.

If I load mil spec brass (308) using Varget and 168 gr. BTHP. max is 46 gr. If I drop back 1-1.5 grain (44.5-45) am I equal to the max load with commercial brass. How does it work?

I loaded some mil brass with 47 gr. of CFE223 same bullet am I now close to the max of 49 gr. for this load?

I also read something that shooting an M1A I should drop back further than what I use in my 700 AAC SD? I have no one local to fill me in on this so I'm trying to learn on my own...

Don't go above 43 grains of Varget with a 168 in an M1A. 42.5 in an LC Nato marked case.

Not all military brass is thicker, but LC Nato definitely is.

I don't recommend CFE223 for an M1A.

Just go buy yourself some IMR 4895 and put 41.5 grains in the case, put the bullet on top to the desired length and go shoot. If your gun does not shoot this load, sell the gun and buy another one!

Good "all around" 168 load with LC brass and Varget is 41.0 to 42.5 as KurtC mentioned. Your Rem 700 can handle a stout load, the M1A/M14 doesn't.

I won't yell at you... it's your face... but that's not how you are supposed to develop a load, by picking a max or near max load and going to town. Do yourself a favor and work up to it.

And smoothie is correct... you should develop one load for the M1a, and one for the bolt.

Thanks from JayKosta and nra lifer 1980
