The #1 load recommendation for the 257 Roy here on the campfire is 72 gr of RL -22 with a 100TSX, of course I was working my way up. I figured I'd see some pressure signs before backing off and seeing as I havent reached the coveted 72 gr I didn't expect these speeds without signs of excessive pressure. Now you've got me wondering. It was mid 80's today so it's not like it was cool out. I have clocked factory loaded 100 TSX's in the 3700+ velocities so I wasn't sweating it too much, just thought I was reaping the rewards of hand loading!
