loaded some 22/250 with IMR 4895 and Nosler BT 55's and first three shots went thru one ragged hole at 100 yrds,next 2 shots opened things up a bit but the gun and load was still well under 1 inch and a 3 shot 200 yrd group was aroung 1 1/2" . Speed was around 3400 fps. I think I will stick with this load combo for a while.
