[QUOTE="SMF, post: 700898, member: 33236"] Okay here's where I am.... I'm working up a load for the new Barrnes LRX BT 173 grain .308. I've arrived at what I think is am accurate recipe. At 100 meters, I am making a single ragged hole. I do however have two questions: Is a 27 fps average spread with an average velocity of 2712.5 fps acceptable for longer ranges (500 to 800 meters)? Also my primers aren't flattening at all, but there is slight cratering on the firing pin impact point. Is this a sign of unacceptably high pressures? I'm seating the bullet 0.05” off the lands. The load is in R-P brass, 42.5 grains of Varget infront of a CCI BR-2 primer. Any input would be helpful. Thank you. Steve gun) [/QUOTE]
