6.5 X 57 Mauser Load Data

[Wachtelhund]

Anyone have any 6.5 X 57 Mauser load data? Specifically for a 1:9 twist barrel. Several months ago I picked up a a very nice sportized T38 Arisaka in 6.5 X .257 Roberts. I rechambered to 6.5 X 57 Mauser. Just started working up loads with 100 gn Nosler BTs and Hornady 120 gn A-Max. Gun didn't seem to like the A-max, but did the 100 Gn Nosler BTs. Tried to powders IMR 4350 and H4895. With both powders groups tighten up as loads increased. Didn't reach max loads with either as just strating out. Best 4350 load was about 1.5". Best H4895 load was under 1". Amasing for an old Jap sportized rifle.

I can scan and email you a really nice article concerning 6.5x57 Mauser reloading from my Jan-Feb 1986 copy of Handloader magazine. Please PM me if interested.

I used and handloaded for the 6.5x.257 - which is very similar to your round - and had excellent results with Hornady 129 gr Interlock and IMR 4831.
