[QUOTE="Shane Lindsey, post: 2219343, member: 25831"] If you have a magneeto speed, I broke in the barrel with about 10 shots on my RUM barrel just to get an idea of velocities. Started low and 1 gr increments up. I cleaned every third round back to steel. I wanted to see how high I could work before pressure signs. Topped out and then backed off from there a few grains. Loaded up in .5 gr increments to find the load and was pretty comfortable knowing velocities and a good load I could go hunt with. Knowing the barrel would speed up after 50-100 rounds. I then started playing with other bullets, powders, and brass just because I like to fiddle. I worked through all the cases before adjusting/testing fire formed differences. 245gr Berger at 2832 FPS with good ES. Not the fastest, but cold bore and follow up are on. [/QUOTE]
