I have an older 10 FLP in .308 with a twist of 1:10. I never did find a load that grouped well with 168's or 175's. I decided to try the 155gr Palma and this rifle printed sub 1/2moa all day long. When I found this other shooters didn't believe me because of my barrel twist, they said I couldn't shoot Palma bullets. Can someone explain to me why my barrel with a 10 twist shoots a bullet that "its not suppossed to". The muzzle velocity is 2950-ish with no signs of over pressure.
