I'd be interested to hear the particulars on that if you don't mind and still have the information.

Without a lathe and gauge rod to make sure you are cutting the face of the crown square to the path of the bore as it exits the results are a bit of a crap shoot.


BTW often need a bore scooe go see crown problems like burs on one side, if you can see them with the naked eye it's really bad.

So before you had technical insight..... and now you just have insults..... hilarious. Now that's twice you've done some excellent long range mouth running..... but you've yet to make a hit. Also, you might want to swing into Punctuation Warehouse next time you're in town..... you're obviously in short supply.

I also find it hilarious that we've seen/heard from folks who've done this successfully with nary an incident, we've heard all the conjecture from the peanut gallery on how it's the dunmbest thing you can ever do, but we've NOT heard from ANYONE who's ACTUALLY done this..... and FHUGKED UP THE GUN!

You spunk monkeys are using Brownells as an argument for NOT doing this..... but Brownells has specific instructions on their website on HOW to do it with a chamfer tool, a brass lapping tool, and a drill.

Here's the link.... just for you two Freddy and Aunt Bea175.......

http://www.brownells.com/aspx/learn/learndetail.aspx?lid=10598

Once again, those who can't will always find excuses why you shouldn't.....

He would use a cotton ball to make sure there where no burrs on the crown.

There's a reason I haven't bought a "crowning tool" from Brownells.... because I've never needed one. Besides, how can you fhugk-it up? If you do, it was a bad crown anyway.... right? Try it.... if it doesn't work, buy the tool... or send it to the 'smith. Do you take your Prius to the dealership when it needs air in the tires?

I've also watched a benchrest jockey use the same method on a VS .22-250 at the range one day.... it made a world of difference on that gun.

Funny how performance doesn't matter here on the fire. If you do your own work, and your gun shoots well..... you're lucky. But, if you drop $5000 on a GAP or Gradous.... it's ok if it shoots like schitt.... because it was built by a "reputable smith". Ask Drew how that's working out.


Seriously have you ever seen a Gradous rifle that doesn't shoot...........

I have one of these with the 11 degree target cutter and have been very pleased with it. It cuts a nice crown and has a guide to keep everything concentric to the bore.

IMO well worth the investment.

I have both the Lathe and the Manson tool and can't really tell the Lathe does a better job. The Manson Tool is well worth the investment.

I've had a Brownells chamfering tool for around 25 years now, and have used it to crown and recrown dozens of barrels. It works great, in fact one of the recrowns was on a Remington 700 heavy-barrel .223 that is still the most accurate factory rifle I've owned. When the barrel was young it would average 5 shots of its favorite load in 1/4" at 100 yards.

As Rancho Loco said, it ain't rocket surgery.

The flutes you see cut in the guide and expand when the guide is tightened. This locks the guide into the bore and keeps everything aligned. The brush is there to hold the guide while it's being tightened.

The only draw back is you need to buy different guides for different bores. I don't think they cost too much though.

IMO, there is a difference in a polish and a re-cut.

in no way is your crown square and true to the bore. That was my point. You started the insults with some shoe tying joke. thanks for showing us the way we should recrown rifles I'm betting all the 12 + guns u have fixed wink this way are .5 Moa shooters. I like my guns to much. To ruin them with a it might work fix. But your are free to do as you please, my original take that if it shoots your lucky . Is right on and I don't have time to deal with dice and card tricks. Sorry your feelings got hurt, because I think your quick fix is stupid. If you can't take some one saying it's not the best way, grow the puck up.

Again..... if it's already messed up... what have you got to lose?

I'm amazed at your ability to judge the concentricity via a single pic taken from an angle.... genius if I understand correctly.

It's not like we're taking brand new crowns and polishing doing this to them.... this is about trying to repair a little nic or scratch.

Still haven't wrangled up that punctuation I guess?

I'm thinking illiteracy and the inability to do simple gunsmithing are going hand in hand here..

I'm still trying to figure out how to hang a shelf that's not 25 degrees off level.

I wonder if after the cut one could run a file to level things off, humm...

I cut my own crown after I chopped off 1 inch of the barrel took a flat file to even it out then did the brass screw with lapping compound I was pretty proud of myself and the rifle shot hell of lot better after I did that.
