Re: recrowning video..... jaw dropper
That's hi-tech gunsmithing right there!!
That is the same way Skunkworks, APA, GAP, KMW, & Robert Gradous do it - LOL!!!!

Re: recrowning video..... jaw dropper
About every 500 rounds I touch her up that way. Brings her right back into MOA
You might think the real secret is in the filing but its all in how you hold your mouth.

I hope you mean the "smithy" and not the brass screw with lapping compound smeared on it!! TOOL INDEED!!
If you pause the vid at 1:50, you get a good pic of how messed up the crown now looks (at least it looks slightly "out of round", but it could be the angle the vid was shot at). Either way...OUCH!

Re: recrowning video..... jaw dropper
Honestly I love those Midwayusa vids. Sure some of the stuff seems a little garage-tech (mostly the earlier vids)or has errors, but it makes basic smithing seem accessible to guys instead of this magic process requiring lathes and such, or 6 months with no rifle while you wait on a smith. Anything that draws people deeper into the sport I like.
Sure that rifle probably won't shoot sub minute, but it would get the job done I bet. His later vids incorporate some slightly more sophisticated tooling to do a better job. I wish they were a little longer though,

Say what you will, but the guy puts millions of dollars back into the sport with donations to hunting /shooting orgs. He gets my business and respect.

Re: recrowning video..... jaw dropper
for what he started with, and what he was working on, its an option thats not out of line really. and it did look better afterwards then before. like massoud says, not everybody has access to a mill or lathe or wants to be out of commission for a long time waiting to get a simple job like this done. what do you all think they used before power tools?

Re: recrowning video..... jaw dropper
Before you put a file on a crown use a brass ball with lapping compound. Not as good as a lathe but, it will follow the existing chamfer and that’s what really matters. The rest is just eye candy.

Re: recrowning video..... jaw dropper
Years ago, I chopped a 270 Rem 7600 on a bandsaw, squared it up on a belt sander and hit the lands with a Brownells piloted chamfer tool. Shot right at 1" with hand loads. Ain't complaining. My buddy killed a 150, 10pt with it about 2 weeks ago.
For a huntin rifle it worked great. Don't think I'd do it to my AE though
Just a thot.

Re: recrowning video..... jaw dropper
I was also thinking I'd at least want a belt sander with some kind of guide to keep the barrel square rather than just attacking it with a hand file, even on a rifle with little to no value.

Re: recrowning video..... jaw dropper
I have shortened barrels in this manner several times over the years. it works fine. I am of the firm belief that the crown is not nearly as important as commonly believed.
While I do have any rifle I want the utmost accuracy out of properly cut and crowned, there is nothing wrong with this method. I have a Marlin 336 that has killed many a critter with that type of crown, and I never once heard the deceased complain.

Re: recrowning video..... jaw dropper
Minute-of-deer accuracy is not hard to achieve. As one of the lucky few who happen to have a lathe at home and an ex-armorer as a husband its easy to forget that not everyone has thier own shop or lots of extra income to put into toys.

Re: recrowning video..... jaw dropper
Believe it or not, I have seen such a thing done successfully with a Remington Model 788, a hacksaw, a file, and a large brass bead/ball.
Old guns with years of three piece cleaning rods used through the muzzle are the candidates for this treatment.
The 788 shot much better (before it was 2.5 MOA, after it was 1.25 MOA) with factory ammo.

Re: recrowning video..... jaw dropper
I think the repair was appropriate for the gun. Why would anybody send an old gun like that to a "real" gunsmith?
Larry Potterfield has forgotten more about guns than most folks will ever know.

Exactly, I am thinking most missed the point here. It's centered on the weekend garage hobby smith, not precision types.
I am sure if Larry wanted to address the precision gunsmithing types he could just buy out the top 2-3 revenue grossing smiths in the country and have them do the 2 minute video instead.

Re: recrowning video..... jaw dropper
I've done this..........shot for groups...........pulled barrel back off (AR-15)...chucked in the lathe (oh yeah...great tool to have in the basement) cut crown to 11º........shot again for groups....and there was no discernable difference
Agreed I would not want a 'smith to do this but I wouldn't think twice about it for a 22 or a hunting rifle

Re: recrowning video..... jaw dropper
Having owned and shot a Win 67 since 1947, it was NOT a precision arm new, nor is it now. Good for minute of cat. It was interesting to see that the bore had been preserved all that time by the bullet lube...just the muzzle face had been rusted and pitted.

Re: recrowning video..... jaw dropper
Well,
for the poor guy who ONLY has
1. a rifle with a bad crown
2. a file
3. a piece of brass
4.no $
it's certainly workable, just please AT LEAST use some kind of square, even if a carpenters square and your strongest reading glasses to check to see if you filed it off (mostly) square to the bore. Hold the barrel and square up to the light and peer close!

Then you would be quite wrong
Get an accurate rifle, ding the crown and watch it drop accuracy. I've seen tests done showing the same thing on BR rifles.

No, Ump, we think how you are constantly working on/modifying your guns is a bit odd.
Did you ever get to shooting that MSG90? Is it grouping better?

The only thing that matter with the crown is that it gives the bullet a clean exit from the bore. Dings will prevent that. What does not matter is how it is crowned, as long as it is defect free. 11 degree, 90 degree, recessed, etc..does not matter.
Speaking of tests, I once read one where the author cut the barrel in different manners, including at a 45deg angle, and crowned it with common hand tools. The gun shot fine, as long as the crown was clean.

I usually just use the pointy stone in my Dremel kit. It's especially nice when it starts to chatter... Leaves a nice "flowery" pattern to the crown! Accuracy Baby!... Accuracy!!!
