Yesterday I tried shooting my resized 405 gr bullets and they shot horribly. A 4" group at 50 yards. I don't know what could have made them shoot so badly as I had high hopes for them. I'm sort of thinking that it may have been the bullet lube (Lyman). I pan lubed the bullets and there was some excess on the bullets and the coating was uneven. As I type this I'm thinking that I should have ran them through the sizer again....dummy.
Do you guys think that could have been the cause?
