    Barrel fowling and accuracy & accuracy testing WOW

    We went out for our usual shoot. I took my NOVESKE SPR with Recon barrel and NF 2.5-10.

    We have been bouncing around with a variety of ammo /powder - Benchmark, IMR8028 XBR ....Accuracy T32 and the famous H322.

    I start shooting my Recon and groups are all over the place. I'm talking 6 inch groups. Three or four of them.

    When we change powders we are always cognizant that we need to run a couple fowlers. I try our 77 gr load with a couple groups of 5 back to back to back. Groups suck. So I grab a can of 69SMK's , wolf primer and H322. I'm shooting my two fowlers at steel then back to paper as I was re zero ing the scope, still confused and speaking inappropriately. Group sucked. I said f%^* €£. Took my AAC mini 4 OFF. Same shit. Try another group and it gets to a little better.

    Mark says, maybe it's settling into this powder? Sure as shit. A couple more groups and its stacking groups sub MOA. I put the can back on, sub MOA.

    It took about 20 to 30 rounds to season the barrel. And get it back to sub MOA. This has not been my experience. I have never seen a high quality barrel shoot 6 inch groups with quality ammo, dirty or not.

    This was quite unique. It shot high quality SMK's rolled to perfection like an 870 scattergun. We usually shoot two fowlers and then try our group with success. I was checking my scope, tugging on the barrel..... I cleaned the gun when I got home.

    WOW. How does the muzzle crown look (just curious)?

    That's pretty fascinating.

    I don't get it.

    Was this a new barrel or one you just cleaned to include de-copper?

    If the latter is true, what was your cleaning method & chemicals?

    Clean barrels don't shoot as well as fouled barrels.

    But they don't go from 6 inches to sub-moa.

    I suspect he had a build up of carbon under the can at the muzzle that cleared itself after he removed the can.

    No it wasn't clean. I was wondering if there was some special recipe of powders that jacked up my barrel in a perfect storm. I may never know, I hope not.

    It's fairly new, it been shot a fair amount, but it wasn't clean by any stretch. I'm going to accuracy test that gun pretty heavy next time out. It will be interesting.

    As Littlelebowski stated, I run them dirty quite a bit. Bolt guns and AR's.

    I'm to the point where I don't want to clean my barrel at all until groups open up. At most I'll bore snake it to remove the loose particulate matter, but beyond that, I don't see a point.

    I've had good luck using KG2 too. But the headache and time involved doesn't pan out.

    When was the last time you shot the rifle before then?

    You are like me. I don't usually clean my barrels after a range session. I don't pay much attention when I go to shooting again, but I have noticed after the first cold bore/fouling shot on a clean gun, the first shot is usually off a bit. Never experienced it taking that long to settle in though. Weird!

    I had a rimfire at one point that was like that.

    Once it got a bit dirty it shot cheap Blazer into extremely tight groups. Not quite as tight as the Remington Eley stuff I had, but it was pretty close. At the same time, it shot CCI Mini-Mags like absolute horseshit.

    Once I had several thousand rounds through it (without ever punching the bore), it started to suddenly shoot like shit with the ammo that it normally liked. We are talking over the course of about 50 rounds. At the same time, the CCI mini mags that it used to hate, all of a sudden started to shoot very well through it.

    Punched the bore, still shot like shit. About 100 rounds later, it settled down again with it's old favorite ammo.

    Always interesting to see the "personality" of a specific barrel. Never know how it's going to be.

    In my experience this is true, but why is that?
