So I decided to try some Cutting Edge bullets in my 260 after trying them in my 338. I had great results with them in the 338, but the 260 not so much. I loaded them per Cutting Edge's instructions. I made sure all of my cases were cut to spec of 2.025 with the inside beveled with a VLD tool, and seated .025 from the lands. I loaded 5 rounds and shot one of them yesterday and it keyholed the target so I stopped. I started with a load of 39 grains of hybrid 100v which on a Berger gives me right at 2600. What can cause this to happen?
