I was experimenting with some different loads in my Remington 700 .222 last week and I experience something that at first had me baffled. The new loads were not very accurate for this gun, just around an inch and it usually shoots under half an inch with most loads. I was most interested in just shooting up these rounds to fire form the cases. I wasn't in any particular hurry. I would shoot, run a nylon brush and dry patch through the bore, double check the last point of impact in the spotting scope, replace the bolt, and then load and shoot again. The barrel was barely warm to the touch. The last two shots were within half an inch of each other, but the Sight-N-See target looked smeared. At first I thought I had driven the Hornady SX too fast and they were coming apart. When I retrieved the target something didn't look just right. When I looked at target backer it was clearly the outline of a 50 gr Hornady SX going through sideways. I'm thinking I have a problem at the crown. These loads were about a grain hotter than I usually load. They showed no pressure signs, but I figure they were beyond the optimal loading for this gun. There had been less than 20 rounds through the gun since it was last thoroughly cleaned, including copper remover. Any ideas what caused this?
