Was shooting CTR at 250 yards from solid field rest and had two hit within an inch, but third was 2+ inches away.

At first I thought caffeine jitters but had good press, etc. I looked the rifle over and saw a tiny chip on edge of rifling; so much for trusting the toe of a muck boot on the floorboard!

Should I just try a round brass screw or mil surplus 7mm FMJ and lapping compound or get a Manson crowning tool. Trying to avoid expensive gunsmith trip with this "peasant rifle."

The holes in the steel are from a BIL who didn't understand that Failsafes weren't Softpoints a few years back. whistle

Brass screw and lapping compound here.. by accuracy, it has worked pretty well for me.

I use either my Lathe or the Manson Crowning Tool and wouldn't think of crowning my rifles with a brass screw .

The lathe will produce the best crown. Not a very expensive job either.

Not so sure the lathe will beat the Manson Carbide Crowning tool , they both are running about equal in my opinion.

The brass screw worked for me on a used hunting rifle I bought.

I have the Manson crowning kit. I cut a fresh crown on all new or used factory rifles I acquire. If a custom rifle has accuracy issues I can't resolve, I'll try a new crown on them. The Manson kit is very accurate.

You'll be out 3 but to try the screw.if Melvin can get good results with a ball burr, a screw should work in the right hands.

It does..

I chuckle at those who say it won't.

Maybe I should have called it a brass ball end cutter.

I did have to cut 1/4" off the end of a barrel (worn crown from overuse and poor technique for pull-through cleaning). Used a file to get it square and smooth, and then blued it. No crowning - shoots great.

That's a bold assertion. Point out where you think I lied.

I've had good luck with a standard 45-degree debur/chamfer tool. I'd give it a whirl and if it doesn't work, move on to something more elaborate. I'm not convinced a dinged crown is always the root cause of fliers so I'd be careful chasing the crown when it could be something else... unless it was a proven shooter before the ding.

Ever bumped into a bench rest shooter that did his crown with hand tools? There's probably a reason.

Funny that expectations are so high for the CTR..... that a single sub-minute miss is cause to question system integrity.

I've touched-up a dozen crowns with a standard deburring tool and a brass screw.... its never hurt anything.... and has led to some consistency improvements.

DS, can you describe your procedure for that?

Take deburring tool..... spin lightly in muzzle (kinda like brass)... Chuck done-headed slotted brass screw in drill... apply valve grinding compound to screw head.... Place screw on muzzle and run drill at moderate speed.

I've also used one of the Dremmel cone-shaped grinding bits spun by hand.... that seems to be the best way to do it.
