7X57 small ring mauser

[LaDano]

I just built a '95 mauser in 7X57. Started with 36gr IMR4064 with Hornady 140gr. I picked up IMR4350 & Sierra 140gr. I have the Lymann and Sierra load books. The Sierra doesn't have the pressure publicized. Should I start at the minimum minus 5%. Just trying to stay in safe levels below 46000cup.

Thanx

I was looking at the 120gr, you got me thinking about trying a lighter bullet now.

I just checked the Hodgdon 2013 Annual Reloading Manual.  It states that for a (139)140 grain bullet, using:
IMR 4064 - 38.1 grs will generate 41,800CUP, and 40.5 grains (Max Load) will get you 45,600CUP.
 So your starting load of 36 grains is a little light.

IMR 4350 - 44.2 grs will generate 39,600CUP, and 47.0 grains (Max Load) will get you 45,300CUP.

Both of these loads will keep you under 46,000CUP.

Thanx again, I'll order it now if it is.

Yup! that's it.  I got mine thru Mid South Shooters Supply.  The price is probably the same, it's the S/H that gets you.  Good luck with your rifle.  I have two 7x57's, and really like them.
