RE: reloading a 300 Ultra-Mag
bigchountry, I appreciate the offer. I just got back from the range. I had scoured out the bore with CR10 last night. At 200 yds, the rifle printed four rounds inside 2", which for me, is acceptable for a magnum elk rifle. I was using once fired Remington brass, 180gr TripleShock Barnes bullets, Federal mag primers and 92gr of RL25. The mv is just over 3200fps at 10ft from the muzzle. If I count the first round, which I judged to be a "fouling round" the group is 3". I waited 20mins. between each round, as I had a 22-250 and a 223Rem to play with.
