Load data for 7x57 Chilean Mauser

[Waynzee]

Hi fellas, I was looking for some load data. I've got a 1895 Chilean Mauser 7x57, Reloader 17 powder, Winchester case, CCI BR 2 primer and 160 grn. Sierra BT bullet. Looking for start and max. load. Thanks.

Don't know if this will help you but, I read (Awhile back) that Alliant list 44gr. of RL17 max for the Speer 160 BTSP for 2669.

That's kind of what I figured because the burn rate is similar to 4350. Thought about starting around 38 grs. of R17 powder but would like input to be sure.
