Home Forums Hunting & Shooting Rimfires barrel threading service???

ok fellas i'm about to send both cz-455 stainless barrels off for a chop/thread. got 2 places in mind and was wanting to get y'alls perspective on the 2 before making my final decision. jim pixley vs karl feldkamp.. one any better than the other as in quality of threads and concentricity of the bore while using a suppressor?
thanks,

Personally I would just take it to a local machinist for muzzle threads. Or even if you have a neighbor with a metal lathe who is an experienced hobbyist. Its not a rocket science type of operation and it doesn't need to be CNC. A manual lathe can do a great job. The most important ingredient is competent machining skills. It could even done on a small lathe since the 455 barrels are removable, as opposed to the pressed and pinned barrels that are usually passed through the headstock on a bigger lathe. Hope that helps.

Exergy is perfectly correct.

And the 455 is quite simple to remove the barrel from. If the breach shank is chucked on center and the tail stock is perfectly centered the whole job is only about 10 minutes. I have done more of these kind of jobs then I can count.
Anyone with a lathe that know how to use it can cut your threads in very short order, and give you perfect concentricity by turning the barrel on centers.

Here's another thing to think about. And I am not sure if there is universal agreement on this, but its what I like to do. Instead of just chopping it at a round number for the barrel length (16.5 or whatever), drive some lead slugs down the barrel with a wooden dowel and mark a tight spot to be the new muzzle. You might be surprised what you discover and how much variation there is. As it stands from the factory, I bet your CZ barrel opens up in the middle then tightens down right at the muzzle.

I will be the dissenting opinion here, not on the difficulty of the job, but on how carefully some gunsmiths will make sure the threads are concentric to the bore. I have had to chop a number of barrels shorter based on nice-looking but non-concentric jobs, a few done by local gunsmiths, though most of the worst jobs were done by the factory.

Any good rifle builder, rather than local smith, will do a good job. The only issue being turnaround time. I will use adco if it's just a threading job. They are usually faster than all the rifle builders I use.

Ed, the one's you speak of are great....but you're going to pay a premium to send your barrel across the country to Karl when there are certainly locals that can do this.

I'm a indicate the bore fan too.

I can't imagine somebody doing this job without indicating the bore, but there are certainly guys out there who don't know what a range rod is, among other things. I would think this would include a lot of guys who own a lathe for threading, but don't do gunsmith work specifically...

Set up takes more than 10 minutes, and then making the threads. Indicating off the bore both sides of the head stock.
