Im hoping to shoot that very 50 BMG this weekend L0L
Its not that harsh. just a load of metal to point
Run a few round through a 45.70 with a brass butt-plate.
That will make the .50BMG feel smooth!
First round, concentrate on hitting the Earth in front of the target as this will get you prepared. It is a shove not a kick. The next round you will be ready and shoot at the X.
Belt and suspenders are highly recommended.
