forgot to mention after I had those two Ruger no.1`s rebarreled with a 27 in bonx barrel and chambered into a 257 weatherby ,I did use my ohlier conograph and with a 100 grain swift a-frame bullet velocity was 3800 fps groups were 3/4 of an inch at 100 yards some smaller,i did get a small keyhole at 100 yards but at 150 yards bullets were perfect with no keyhole at all. using a rifle like the 257 weatherby , 264 win. mag or any rifle cartridge that uses this high of velocity really smacks an animal dang hard,P.O. Ackley liked high velocity cartridges and in his book he wrote about bullet speed when he tested it on animals and effects when hit with high velocity bullets.the powder I used was reloaded22 at max.
