AR Heavy Barrel, Lots of Chips, and Weight Loss.

I don't think the barrel is trashed at all.

As for heating up, we'll see when I take it out next the time and shoot it cold.

I am completely happy with the PMC and will buy more of it.

I am not happy with a gritty 5-1/2 pound military trigger and shooting off a sandbag. Not conducive to accurate shooting.

Ya'll have fun busting balls.

haha sure do. Give american eagle 50 grain varmint polymer tipped ammo a try. It's shooting great for me with a 1/9 twist DTI barrel. It's some of the best shooting cheap stuff I've found.

Blowing out a hole would be the very definition of OH $HIT!

I am a fan of PMC bronze. I roll my own but have personally seen it run well in 6-8 different rifles w/chrome bore M4 profile to several different quality mfg's. I like reloading in PMC brass as well.
How did you crown it? That can make a big difference too.....

The only crown it has right now is from spinning it against a disc sander.

Just squared the fence to the disc and pressed the barrel into the disc while spinning the barrel against the fence. It trues things up, but is hardly precise.

I don't have a crowning tool and bushing small enough for a .223. All I have is .30 caliber and over. I need to find a place and send it out.

Or call Pacific Tool and Gauge and buy a small crowning tool and bushing set.

And that PMC Bronze shoots tight groups out of my H&R .223 Handi-Rifle. Other brands spread out. My Lou45 Mini-14 loves the American Eagle in the above photo.
