Turbine1: Both of my Varminters in caliber 222 Remington Magnum LOVE the plain jane 50 grain Sierra Blitz bullets!
ALL manner of Varmints have "succumbed" to this accurate and lethal projectile from my 222 Magnums.
My Browning though does prefer BLC-2 powder whilst my Sako enjoys H 4895.
I use Federal 205 Match primers in both and Remington cases as well.
Best of luck to you with the new/old Remington 722, and good shooting right back at'cha!
GO Seahawks (I delayed my departure to our high country archery Elk camp to watch this game tonight so's the Seahawks had better put on a good show).
Hold into the wind
