I loaded some 250 grain Barnes XPB's for my Raging Bull was using 2400 powder 27 grains seem to not group very well but shootable. I decided to back off to 25 grains and try again. Wow what a difference . Shot a 1 inch group at fifty yards over bags. 4 rounds in the inch group and one about 1.5 away from the rest,which I am certain was me.Does anyone have an idea as to how fast these might be traveling,with 25 grain charge.I don't have any data,and don't own a chronograph. Has anyone used these bullets on deer ?
