I have had to wait in barrels in the past, now I order a year in advance and stick it in the safe. The last Bartlein that I ordered took 7 months but I knew that due to updates that was posted on the Hide.
That’s crazy, I had a 22-250 that I loaded 40gr Barnes @ 4200. I would shoot song dogs and at a 100 you could hear the bullet hit before the gun going off. That barrel didn’t last long but damn it was fun, I can’t imagine 5200
