Years ago I tried these in my 7mm-08 Browning A-bolt micro-medallian and after shooting a few the groups started opening up. The barrel also seemed to be getting excessively hot. When I checked the barrel the gun was severely copper fouled. It took what seemed forever to get that copper out of the barrel and I never used them again. Has Barnes changed the copper alloy they were using on these early bullets and did anyone else experience this in "the olden days"? I've stayed away from copper bullets but they seem to be getting popular. I see some are coated.
Give me some thoughts on the new copper bullets please. I don't re-load anymore but have been a lifelong believer in Nosler partitions.
