I’ve loaded and tested tons of Barnes. I assume you are loading 6.5 creedmoor. Barnes like to be at least .030 off jam. All mine like .050 off and one shot well at .1 off. I left Barnes and went to hammers because I just couldn’t get Barnes and the tips were wobbling when rolled on a table. Emailed Barnes and never got a reply. Switched to the tsx with no more issues, but again I couldn’t get them. As already said, hammers will foul much less and are available.
