[QUOTE="Brent, post: 25519, member: 99"] Yes it is normal. Once it's fouled, after a couple three shots it should stabilize though. This is the same reason my barrels are "prefouled" before hunting with them. 3 inches at 25 yards seems a bit excessive, just make sure your mounts are good and run your scope through a repeatability test and this should verify if you are in good shape or not. My 300 Ultra shots about 3 moa low on the first shot with a clean barrel, sometimes two shots until it works up and stabilizes. It also seems the groups start opening up at just about 25 rounds too, with the combination I tested last anyway. [ 02-24-2003: Message edited by: Brent ] [/QUOTE]
