[QUOTE="Crop Damage, post: 337217, member: 8652"] Thank you Fitch. Now I'm slightly concerned! My COAL is 3.70". I don't know what pressures the barrel can withstand, the rifle is the african plains rifle from the remington custom shop, and the barrel is 26" long, if that helps. As far as I can tell the bullet is not touching the lands. I marked the bullet with black marker and ejected the cartridge without seeing any marks. There is probably a better way to check that though. I have not got any load data from Berger, which is why I'm having to guess the figures for this load. Looks like the chronograph will tell me a lot, and I'm going to have to get a ballsitics program. I definitely do not want to have the rifle blow up in my face later this summer. I can step it down some, but how are there people claiming to get 3400 + FPS from this bullet using different powders, when I'm maxed out at 3100? Longer barrels maybe? I think I saw those loads on another reloaders website. I don't really need any more speed or power out of this round, if I can get it to group well at 700 yards. Thats as far as I want or need to shoot, and more speed won't help me too much I don't think. Thank you for the good info, that's very helpful. [/QUOTE]
