Exactly my thoughts. I ran a pretty hot load thru the 260, no issues, switched the barrel to a 6 Creedmoor and pierced primers, craters and even blown primers. Load was a factory Federal blue box, velocity was all over the place. Started getting wonky cycling issues. Reached out to Slash about...

I have an old laminate H&R Handi 450 Marlin and probably 200rds of factory FN 350gr Hornady factory ammo. It would flat put the hurt on big pigs and deer, hole the size of your middle finger in and out. That...
