I have a Remington SPS Varmint that has a 1:12 barrel and shoots a little less than 3/4" at 100 yards with 50-55gr NBT/Varmageddon bullets.
I also have a Stag Model 6 Super Varminter with a 1:8 twist that shoots 1/2" groups with the 50-69gr class of bullets with select loads.
Am I gaining anything by keeping the Remington around? Thinking of selling it as I rarely use it. Benefits is not having to chase brass and potentially having a cast boolit shooter.
I also have a Kimber Varmint in 22-250 that is super accurate and would satisfy any varmint shooter with accuracy and terminal performance.
