I get 'sorry no matches.' I spent about 20 minutes using search, didn't find a single dedicated thread

Shoot it, but you don't get it hot enough to brand cattle is Noveskes recommendation.

Drop a straightness gauge down through to ensure it actually is and there's no burr on the gas port in the bore, then just run it.

I've never taken a single weapon I have bought and just shot the hell out of it the first day. I'd shoot a couple boxes of pistol rounds or 20-40 rounds of rifle rounds and then clean up when I got home. I've heard of shooting a couple of rounds, swabbing the bore, using a bore brush, run a clean patch down the bore and then shoot a few more rounds. I just don't have the time and never found that it caused problems with any of my ground hog rifles such as 22-250 or 220 Swift. Both would shoot 5 shot 1/2 inch groups all day long with reloads at 100 yds. and I didn't do the tedious barrel break in procedure of shoot a few, clean and shoot a few more.

I've heard of all kinds of random methods people use, but personally after a initial clean/lube after purchase, day one is about 100-150 rounds over about 30 mins, take it home and clean.

From then on, sky is the limit (or the depth of my pocket to afford ammo :( ), with regular maintenance.

Now if I ever get into precision rifles, perhaps I'll take a closer look into this, break in business. :sarcastic:

The procedure I keep hearing is to shoot 2-3 fmj rounds, then blow some air down the bore, then lube/run a patch down.

The idea supposedly being that the fmj will tear away any loose shards in the rifling and/or gas port. The compressed air will blow these small shards away, and the lubed patch will . . . Uhh . . . Phase 3 is "Profit"

If your barrel was HP/MP tested, and test fired this is needless

Took me about 12sec.
