Put together some ammo for the 257 Roberts.

117 gr Sierra SPBT, 35.0 IMR 4064 W-W +P cases and CCI 200 primers.

First three went .625 center to center 2 1/2" high at 100 yards.

I think this may make a decent Blactail deer load.

I think you'll be happy. The Roberts is a gentleman's calibre possessing killing power far in excess of its paper ballistics.
