1:11 twist 22" Barrel Mauser

[usabaker]

I'm loading for a Mauser in .308 Win that has a 22-inch barrel with a 1:11 twist. Has anyone here loaded for that combination before? my initial thought were Sierra 168 BTHP with Reloaded 15 but now after looking a number of the relading spec's not sure.

Be intrested in anyone experience and thoughts,

Thanks, Bill

Yep, my M1a has a 22 inch 11 twist barrel and I shoot( or used to, dont do so much anymore) handloads using 168gr Hornady, Nosler and Sierra BTHP's over 40.5gr RE-15. Max is 42.0gr in the M1a IIRC but accuracy isnt as good as the lighter load.
Of the 5 rifles in 308 I still have, 3 hate it and the other 2 tolerate it. My go to powder for 308 was always IMR 4064. I had one load that gave good results in all my rifles at the time and 43.0grs pretty much duplicated Federal GMM.
IMR 4895 is a good choice too.

A friend gave me nearly 15 pounds of Re 15 most 20 years ago because neither of his Chandler M40a1's liked it and after Sandy Hook I ran out of IMR and couldn't find anymore so I worked up a load with the Re 15 and still have a bunch left.
With my interest in guns, shooting and hunting being almost nonexistent for several years now they may do me the rest of my days.

My go to powder for 308 was always IMR 4064.

In all the reading I have been doing IMR 4064 seems to the powder that pop's up the most. I've used RE-17 with my .243 Win in 100 gr. BTSP Interlocks with great results so I thought I might get the same out of RE-15; Maybe not now. I appreciate the help and information.

Appearantly it does better with heavy bullets in 308. Seems I remember reading a magazine article 14-15 years ago that stated Alliant had won the contract to furnish powder for loading 7.62mm M118LR sniper ammo and RE 15 was selected.
I do know it's a very good choice for heavy 5.56mm loads. 24.0grs under a Hornady 75gr bthp is a really accurate load and so is 24.9grs under a 77gr smk, which duplicates the Mk 262 mod 0/mod 1 round.
