This next summer I'll be trying some Swiss and see if I can get those Barnes to group at long range, along with the 275gr BE.
But........... that thing will shoot that bullet with pellets very accurately

I spent a lot of time comparing 777 granules and pellets with a chronograph. I was looking for variance of velocities and moisture how it effected the loads. I think you would save money if you bought a Chronagraph and used it periodically when shooting. Cause I don't think you would ever use pellets again.
