I got a TC Venture 22-250 a while back that I plan on using for varmints up to 500yards or so. It has a 22" with 1-12 twist. What bullet weight/ powder combo would be most likely work best with that twist rate? Any advice or tips as this is a new caliber to me?
On hand I have 40,50, and 55 grain v-max bullets and IMR 4198, Varget, and RL-15.
