Crowning Glory! crowning a rifle barrel, BRNO model2, 22 rifle.

[@craftyha]

I was a sniper on a hostage rescue team for years . We did our best to preserve the crown on our rifles. Often wondered about how to repair/ resurface. Thankyou now I ( we) know.

Hi Bill, thank you for your feed back. It is an honor to have comments from an experienced sniper.

I had a german 22 lr anshutz and it had a dent in the crown. I used a bronze flat head screw and a drill with some wd 40 for oil and I spun it around for a bit and made a new crown. It worked.

[@robdevoe1057]

Could we get some results on paper please ?

[@elizabethkennels3076]

Excellent workmanship and outstanding Photography. !!

[@leokimvideo]

An excellent crowning achievement and right on target

[@ozzistraightshooter9273]

Thanks Leo

[@mikebeddingfield2144]

It's amazing how a little attention to the small details can make big differences, that said you never proved that this small difference made a improvement! The after result was never shown

[@takedeadaim8671]

You might want to use a heavy dose of dark cutting oil when using the reamer. Your tool will last longer and you won't get the chatter in the finish. Hope it shoots well for you.

[@nelsonm5032]

excellent job! don’t have a 90 but plan on getting a 110. hopefully it works out… cheers.

[@MadDogSmitty]

Checked it out. As soon as Brownells get the drill bit in I’ll be Relining a 1894 Stevens Favorite 22 I’m thinking of keeping the muzzle looking original. But just for the aesthetics. Looks like I might want to ?? Just to baby it.

woooow

[@schubi128]

If the groups are at 100 meter they are quite decent indeed.

[@mattar63]

Also swapping to a 4 jaw chuck and keeping the concentricity in line with the barrel bore. and, cut the entire swaged end of the barrel off! If you didn't know it's two pieces. Have a close look you'll see where it is joined. Recrown and now you get that group really small. No front sight of course but that's the cost for a small group. Also grind off the rear sight as it is a shrink fit and you'll release the pressure around the area in front of the chamber.

It would be nice to know if it did make an improvement.

[@johnutting9615]

Nice crowning job ,where are the results from after the crown rework. You have left us all hanging on a string .

[@ozzistraightshooter9273]

Hi John, My preliminary testing is showing an improvement. I need to get back to the indoor range to make a meaningful comparison. I will post a new target when I get a chance. The rifle was quite accurate to start but I believe it has made an improvement. I look closely over every barrel I get hold of. I have seen some excellent crowning jobs and some poor ones even big variations in the same batch of new rifles. If you are having accuracy problems it is definitely worth looking at.

[@pietrobernini4471]

In the final part of the video you can clearly see that the flat surface of the end of the barrel has some sunburst-shaped irregularities due to the milling. You should have used the lathe.

[@talodon4589]

Very good informative video..👍

[@22lr_plinking]

Updates? Results? Been 7 months lol

[@tonymcveigh8789]

Did it work you didn’t show the after targets?

[@le3045acp]

its been a year so lets see the groups since the recrown by the way i sometimes put fine grinding compound on a qtip and put in the last 1/4 inch of barrel then fire a round i do this 3 times and it will finish off the new crown i only do this if it seems it didnt improve as much as i feel it should

[@tonynapoli5549]

Thank you 👌

[@roybertalotto6355]

Since you have a lathe, there is no way I'd use a piloted crowning tool. I don't like putting anything in the bore and especially in the muzzle.....Use a nice sharp ground tool with plenty of high Sulphur cutting oil and cut from the bore out to the OD of the barrel......I've found a 90 degree crown, cut straight across the muzzle is the easiest to cut accurately and afford the best accuracy ........And if done properly, no need for a ball bearing and lapping compound.....Good Luck!

[@ozzistraightshooter9273]

Hi Roy, Thanks for your comment. Yes I agree there are many ways to crown a muzzle and they can all work well. The crowning tool definitely works well and I have had amazing feedback from people who have re-crowned their rifles with this method. Your method works well and so do many others. I am not saying one method is better than others.

[@roybertalotto6355]

Understood...Keep up the good work!@@ozzistraightshooter9273

[@javiersp01]

Hi. did it go better?

[@audieladd2476]

Can't wait to see the after groups, however I noticed that this video was posted months ago. Were the after groups that bad maybe? Do you now need a re-barrel?

[@schubi128]

I was wondering the same

[@wm.traynor1143]

@@schubi128 So am I but he does not seem to have tried it out😥

[@gutheres5788]

ótimo video !!!!t onde posso adquirir eddas ferramentas ?

[@quazarpulsar]

My dear, could you help me with how do I remove the front sight from the cz model 1?

[@lucianoparin9351]

hola buenas noches donde puedo comprar esas herramientas de corte para hacer el trabajo , gracias

[@syedkhaderi6847]

Nice job, how mm was the ball bearing.

[@pop62]

10mm

[@syedkhaderi6847]

What degree cutter was used.

[@ozzistraightshooter9273]

I was using a 110 degree cutter. My opinion is that keeping the edge of the crown uniform is more important that any particular angle.

[@flyerh]

I have an Anschutz 54 action target rifle (1813 super match). It has an 11 deg target crown. Now I am totally confused.

[@ozzistraightshooter9273]

11 degrees is the angle measured from a straight line across the muzzle. The included angle would be 180 minus 2x 11 degrees which is about 158 degrees. Most crowning tools measure the angle across the front of the cutting tool. It is unfortunate that the angles are measured from different reference points as this is confusing. An 11 degree cut is easy to do on a lathe when the barrels is set up but often a sharper angle is cut across the lands at the muzzle with a crowning tool. If you look at the lands at the muzzle with a magnifier you will often see a different angle at the tip of the muzzle on the end of the lands. Facing off the lands on a lathe will often leave burrs. 11 degrees is a convenient angle that keeps the end of the bore recessed at a safe depth. I don't believe it is a magic number. Uniformity is more important than any specific angle. That is my experience anyway.

[@rw3175]

15m mate thats not that good ive seen model 2 shoot groups like that at 50m

[@andrewcampbell4396]

You guys have lost the plot, you have no idea if the bore is concentric with barrel. Surly this needs to be established before anything else can be considered?

[@morgan-tv]

Seems like the result is not good.

[@ronalddavis]

dont talk so loud your hurting my ears
