Well after getting back from the RX18 class, I made it to the range on saturday. The new ammo works really well as far as accuracy goes. It's the 175 gr Federal Gold Medal Match in .308 Win. only had to dial 1.4 mil elevation to go from a 100 yard zero to being on the bullseye at 300 yards. my rifle is a POF P308 with a 16" barrel.
Here is my best group at 300 yards. The others were a bit bigger at around 2", but I was struggling with failure to feed problems. Anyway, I think this should get me to 1000 yards without a problem. I'll probably move up to the new Federal Gold Medal Bergers when I try to go beyond that. But for now the max range I have access to is 300 yards.
