[QUOTE="Doublezranch, post: 1480919, member: 32664"] Couple of things with 33.... First, it’s very unstable the higher temps it sees. I mean off the charts unstable. I shoot it in a couple of my rifles and I have to back it down 2+ grains to keep pressure down in the summer. My custom 300 rum shoots 100 grains in the summer, 102.5 in the winter. Second, I found that 33 will leave your barrel super dirty after a few rounds. To the point where you will loose accuracy after 6 shots. Third, the increased velocity will likely wear your barrel much faster. I’m seeing this in my 300 rum. 33 is a great powder for velocity and accuracy if you like a rifle that loves to be pushed hard. I would try using the Berger Bullet seating chart. If anything it will dial your bullet to where the gun likes it with 33. My 300 rum likes the bullet .010 off the lands with 33. I have some other posts on the site that I tested 33 in it’s infancy. It was incredible in the North Dakota winter, but it was scary unstable in the North Dakota summer. Jayson [/QUOTE]
