My Ruger M77 in 220swift is one rifle I really regret selling.
"Given adequate penetration, a larger diameter bullet will have an edge in wounding effectiveness. It will damage a blood vessel the smaller projectile barely misses. The larger permanent cavity may lead to faster blood loss. Although such an edge clearly exists, its significance cannot be quantified".
I missed it till now. Looks great glad you could use the brass it was just collecting dust on the shelf here. My plan did not work out, I was sure once I mailed the brass to you I would find a great deal on a 220 swift and I still have not!
