6.5 x 57 AI

[Bugs]

Folks. . . . Just began working with a new calibre,new to me, at least), the 6.5 x 57 AI and I'm fishing around for any advise anyone can pass along. The rifle is a Goodling/BAT that originally belonged to Kerry Shenk. I'm using brass that was formed from either RWS or Norma 7 x 57 brass. Chamber is a .294 neck and the brass I have has been turned to .014. The rifle has been an indifferent shooter thus far although it will be wearing a new Nightforce this weekend and I can finally purge myself of the cursed 8.5 x 25 LRT that has haunted me through about a half a dozen rifles. If anyone has any advise on any pet loads or other experiences, please pass along. I'm looking for good 1K loads as well as a few good loads for the "groundhog" format.

Thanks,
Bugs

Hope it ain't shot out is all.

I would start using RL 22, H4831Sc, or VIN N560. PMC primer and a 139 lapua scenar or 140 berger vld.

You got slightly more case capacity than I do 6.5x55. I would imagine that somewhere in the 50's for VIN N560 would get you to 2950 fps with the 139 scenar run into the lands.

RHINOUT!

Bugs,

I'm considering the same cartridge and would be very interested
in your experiences in developing loads for the 6.5x57 AI.
Please post them or send me a PM when you have some results.

This is the same cartridge,depending upon throating) as the .260 AAR which is in Ackley.
