I suggest you try the Searra .85 HPBT Game Kings or Match Kings. They are extremely accurate. I have killed more than 50 deer at up to 300 yds. A fox at 600 yds. Maybe 1,000 wood chucks with them out to 500 yds.
My Winchester Mod. 70 Varmint manufactured in 1969 with a 24" stock varmint barrel would shoot 1/4" and less 5 shot groups at 100 yds. before I shot out the barrel.
I reloaded using CCI-BR2 primers & IMR-4350 powder.
