Gunsmithing I'm wanting my CZ re-barreled but with a twist....

[BenY 2013]

So I love my CZ 452 Varmint, but want to squeeze a little bit more accuracy out of it. I recently won a 1/2 off certificate to Rock Creek barrels so I am planning on using them! Would love someone to recommend which groove for this as well. I think I would prefer an Anschutz chamber. The twist is, I would prefer to watch the gun get re-barreled, I have talked with the guy from BPR in Indiana and he was more than happy to do so with me, but that is a very long trip. Is there any place closer to AR, that might allow me to watch as it is being done? I know its a different request; however, I am planning on being a machinist in my career and would like to watch someone who is experienced in it already! If there are not any places that would allow it and BPR doesn't work, I won't mind too much just sending it off to have the work done. But I want it done well! Who would be good for it? AND not overly expensive! Thanks for any info guys!

Also feel free to chime in about what to order from Rock!

Any ideas?

I learned a little of the gun trade from a mentor/friend who had 30yrs experience hanging out his shingle. I think he put it this way: "Always, always, always, do your work outside of the view of the customer. It's not that you're hiding anything from them, but customers are funny. If you charge an hour's worth of labor to perform some maintenance to a rifle, but have figured out how to do it in half the time, customer's think they should only be charged half the time. A gunsmith has to eat, and there are times when nothing comes into the shop, so capitalize on the work when you have it. Showing the customer how much time it takes, or how to do it is not a good recipe to stay in business."

With the internet these days, I can see some 'smiths not following this rule, but it still seems odd to me...

On the twist; what type of ammo? Subs, standard or high velocity? Seen everything from 14-18 twists, but always (believe it or not) saw best performance with an 18 twist...

Edit: P.S. I'm assuming your 'smith is comfortable with metric threads?

I had never thought about it like that! That is a pretty good point!

I'll mostly be shooting standard and subs in this gun, I'm not a fan of high velocity for this type of gun.

The guy who I am considering for the work has worked on 452s before and was fine with the idea when I brought it to him a while back. I was just wondering if anyone had any better recommendations for someone to do the work?

I would go with a standard 16" twist... thousands of World Cup, Camp Perry, and Olympic smallbore rifles with 16" twist for the last 100 years can't be that far off.
I'm not certain I would go with the Anschutz chamber, but I'm drawing a blank on the name of the chamber I WOULD go with.... it was a very popular .22 LR chamber design in the IR50/50 Benchrest world.
As I recall (not necessarily correctly...) the Anschutz chamber has a lead angle that is not "perfect" for accuracy, but is very tolerant of different bullet shapes. There are better chamber designs for accuracy... the Anschutz is not BAD, though. They do know a little somethin' about smallbore accuracy!
I would ask the folks at Hart, Kreiger, or Shilen what chamber they recommend, and go with that.

Bentz chamber perhaps?

 

[Beyschaefer]

Not the one I'm thinking of... the Bentz is loose in the back for use in semi-auto's.
Still drawing a total blank... dang it.

 

[Beyschaefer]

Time Precision iis the design I was thinking of!
When it comes down to it, pick a good smith that understands what you want the rifle to be, and trust them on the reamer design... a good RIMFIRE 'smith, that is.

I really appreciate the info! Thank you, I wish it was more simple, there are ALOT of .22LR chambers..
