Federal primers are more sensitive but I'd guess that is a rifle or headspace related issue.
Sounds like Nosler has some over sized brass, seen this happen before with there loaded ammo. Lite primer strikes is the key.
Maybe I'm missing something, but wouldn't oversize brass hold the cartridge farther out in the chamber and make for heavier hits?
When I stated oversize I was meaning pushing the shoulder farther back than specs. Causing excessive headspace and causing lite firing pin strike as the round isent head against the bolt face. Undersized would leave for stiff bolt closing as the shoulder is being crushed fit to the chamber. Would rather have this than the other. Oversize is pushing should farther back out of specs.
