This is pics of a Peruvian that has been made into a small ring and it is a small thread. Karl Kampfeld did the faux G33/40 cuts. It will become 250-3000.



I would like opinions on this build. It will be a little while before I get started on it.
Butch

Looking good so far!

Keep us posted. I'm looking forward to seeing it progress.

22WRF,
I understand and I will do that in a couple weeks. Do I need to decide an a trigger before fitting a 3pos safety?
Butch

Ahhh...what's that big cut on the R. side of the ring?

Duane, I wanted to make sure it would eject a long loaded round. I was thinking 257 Roberts at the time. Probably not necessary, but I don't have any experience with that cartridge.
Butch

How does this small ring/small thread stack up against pressure? I'm thinking of the usual discussion that follows a post on the use of a pre-98 receiver with modern ammo- like in a Swede.

Beautiful work; thanks.

I think the Kurtz was small ring, and small tenon and it was used in 250-3000. I am not qualified to comment on what the max. you can use on this setup. I'm certainly not worried about it with the 250-3000. This one will be carburized or case case hardened after all the metal work is done.
Butch

Just wondering .. why start with a Peruvian instead of a lesser(cost) mauser.

I've seen a few turks turned to small ring.

Blackburn trigger sounds good. richj, I bought it from Trez Hensley and it was already a small ring and also had a great bolt with a nice looking bolt handle. It was done right and was cheaper than buying a receiver and having the work done.
Butch

I should have added.. It is very nice. good luck.

Timan or someone once posted a strength comparison. IIRC LR/LT was not much stronger than SR/ST. But I often misremember.

How much do folks typically remove from the left wall, or rather, what thickness usually remains?
It looks like KK went deeper than a typical G33/40.
Butch, sorry- but the way the front ring has been hacked into {ie; the RH porting} is a shocker ..
..the reduction in ring dia. I dont have an issue with, If one cant find a good Mexican, grind a good Peruvian.

About .060.
Butch

Butch: No one else has asked..but there must have been some compelling reason to chop up a Peruvian...Was it trashed in some manner?

My first uncontrolled response was to bite a donut out of my shorts.

I am not too fond of the notch in the receiver and the missing charger hump, but I thought the "small ring" treatment was a common upgrade an Peruvians.

You will have to ask Trez Hensley. I bought it from him and I have done the G33/40 cut. The rest was done by some other person. It had the receiver ring reduced, the charger hump was gone, and the receiver was tapped when I bought it.
In spite of all that I believe that it will turn out to be a very nice rifle. Yes it will be recased.
Butch

This looks like a great example of what can be done to resurect an action that many would turn their nose up at because it was not "original". Great job!

Butch: OK...that's compelling reason enough...save what you can!

This one is a way off for further work. I have 3 in progress now and hope all of them are done soon after the first of the year. Other than caliber, I'm not sure which way I will go with it.
Thanks Butch

Butch that's nice! I honestly don't think I would worry myself with the lightening cuts on the sides. They are a pain in the butt to bed, can't be seen once the rifle is finished and don't save enough weight to concern yourself with.

I look foward to seeing more pictures of this as it progresses.

Ditto.

I think some people get carried away with lightening rifles. About 15 years ago I was out on my mountain bike getting a little exercise on some local trails. I took a water break at a scenic overlook and struck up a conversation with a fellow biker. He was a "techie" (he in spandex, me in cotton canvas cargo pocket shorts to complete the picture) and felt compelled to talk about all the wizz-bang stuff on his overly expensive bike. His latest acquisition was a titanium seat post costing "X" dollars which he claimed saved him "Y" grams of weight.

He was in average condition, but certainly no competitive olympic athlete that might have actually benefited from such a miniscule savings to gain a competitive edge. I turned my water bottle over and squirted a shot on the ground and exclaimed that I had just saved the same amount of weight and didn't spend a dime. He just shook his head and rode off.

I'm sure he thought I was as much of an idiot as I thought he was...

P.S. Ditto also on "looks great" and "looking forward to seeing more pictures"!

Thank you, I like happy endings!

Ditto... X2 on lightining cuts

The G33/40 cuts were for my personal wants. It was not to lighten the package as it is nil and if I make the cuts that are under the stock line, it will be because I want them there, not for any lightness. It might end up with a very nice heavy walnut stock, who knows. This is the idea of building a custom, build what you want and if the rest of the crowd likes it, that's good but not why I build them. Don't you get tired of some of the cookie cutter customs?

If you go to all that trouble I would do the cuts. I don't see any benefit except that you will have then done a faithful recreation of the G33/40. Without the cuts you will only have a cosmetic recreation. IMO

the cuts do present a problem, if you don't feel like fooling around with clay there, bed the action in the white first, then put the cuts in the rails.

merlinron,
I know what you are saying. I do a few glass stocks but learned my lesson that I am not a wood stock person. The wood stock rifles that I have are not bedded in glass. They are wood on metal. When this one is stocked with wood, I won't have to put putty in the cuts as I would if I did a glass stock.
Butch

Well said, Butch: I seems we have lost the meaning of "bedding" a barreled action!

Bedding means close wood to metal contact. Whereas "Glass bedding" means put some plastic between the wood and the metal????I don't get it!

Why not just "bed" it properly in the first place?

Duane,
You are very correct. If you look at the inletting and bedding on my wood stocks, you will see some very fine skill and a lot of hours work. Even I can pookie a glass stock.
Butch

Does the machining you had performed require re-heat treating the action?

butch,
right you are, and shame on my red face for assuming everyone glass-beds everything these days.

I personally think so as virtually the whole top of the receiver is below the case. With the front ring reduced, the charger hump removed and the G33/40 cuts leave very little case hardening.
