As part of an ongoing series on what to look for in a custom rifle, gunsmith John Stewart tells us all a little more about the barrel crown.
John Stewart of Kiote Corp writes: Everyone knows a barrel should be crowned. But not everyone pays attention to what kind of crown should be used, or how deep it should be, or in some cases, when a crown is contraindicated.
For 90 percent of my applications, I use a 10 degree Cooper Crowning tool. I only recess the crown by 0.100”. I find that this type of crown serves most of the practical and hunting shooters, affording more than adequate protection to the muzzle should it be dropped or banged up.
It provides a concentric and parallel bearing surface to the muzzle ensuring proper alignment and interaction with the projectile. It also ensures that the lands are cut parallel with the muzzle and ensures that there is an even bearing surface on the projectile as it leaves the barrel. A properly cut crown, on a quality barrel, should show the clean cut lands of the rifling at the muzzle.
There is no real technical reason for why I only cut it back by 0.100″. I’ve found that in the cases where the consumer uses a muzzle brake and/or suppressor, this depth allows easier cleaning of the muzzle than a deeper cut crown.
I find that almost no one thinks about cleaning the muzzle/crown of their barrel. Especially in the case of brakes and/or suppressors. The blow back that accumulates on the crown doesn’t take long before it quickly and severely affects accuracy.
And when those people do clean it (only after my prompting and sometimes scolding), they use sharp objects like a knife or razor blade to scrape the fouling off. BAD IDEA! While you’ll probably not gouging the surface, you are etching it and literally destroying the crown in microscopic ways. It takes longer but it never hurts the barrel to use a bronze brush and a little elbow grease.
It means the democratic socialists haven’t taken over yet, but they are still trying.
They forgot to put the decimal point in between one of those 9s.
Stupid people, stupid places etc applies.
Girls (and guys) quit shacking up. Quit shacking up with crazy. Keep it in your pants.
If you want a gun get one but it is not a talisman to overcome stupid.
Interesting post on the mechanics of cutting a crown, but I have to agree with Eric and Red. Need more input on the what, where, why’s, how is covered.
Have they fixed he lip at the front of the frame, underneath the new radius on the slide?
I already do, it’s called a Winchester model 1892, chambered in .44 wcf (.44-40).
Edit: I also have two single action revolvers chambered in .44 wcf. Those along with my side by side 12 ga. coach gun, I’m all set.
For a couple hundred $$$ more, you can get the excellent ACOG with the PA ACSS reticle. At least then you know what you’re getting.
It’s a Glock Commander. I would prefer a 26 slide on a 19 frame, but I’m not on the design team.
People have also called for 26 frame with the 19 slide; more akin to mating an Officer 1911 frame to a Commander slide like Colt, Kimber, and Sig have done.
I got the Remington V-3 for my grandson for Christmas, it shoots flawlessly when you can get the shells in the mag. tube. I contacted Remington this morning and they want me to send it back to them. has anybody else had this problem.
