So yeah after all the council and guidance from everyone on here I head out today to break in my barrel. 6 boxes of HSM trophy gold 185 gr Bergers 300 win. Umm yeah so break in was almost 3 hours followed the break in from precision magazine, takes 50 rounds with some serious cleaning rod work involved. I finally get to zero after letting my barrel cool, had to wait about 5 min between each shot so my barrel could cool down, an hour or so later I finally get a sub MOA group bench rested on a lead sled, I'm super pumped! Wait for it! I put my turret back on and it moves past zero stop, I'm thinking what the heck is my turret broken, of course not! my dumb @$$ failed to bottom out my turret before taking it off. Yeah I just said that. I shot 3 boxes of ammo today at almost $50 a box. So incase anyone gets frustrated and wants to call it quits when it comes to preparing for season just think about this screw up. I'm headed back out tomorrow morning to put this thing to bed once and for all.
Don't feel bad. At least you are not working with a newly designed factory cartridge, with an experimental barrel, on a build that has extremely tight tolerance. Had to shave material to facilitate thermal expansion. Still not sure my scope is tracking 100%. It's sub moa at 100yards with cheap factory loads, but still shooting a 1moa flyer out of five shots..
