So you are saying Someone out there is making guns and selling guns in a Country that is a CIP signatory that are not safe of commercial use when shot with commercial ammo ?

In your opinion does setback constitute a unsafe situtation if the user is shooting factory loaded 6.5 swedes from that rifle ?

I think a swede rifle that setback with Hot handloads is very different from one set back with relatively sedate US manufactured ammunition.

Then again, the hottest handloads I have assembled don't flatten OR crater the primer like any of the factory norma ammo does, much less the military issue ball ammo....

And my hottest handloads can be neck sized several times before I am forced to FL size to chamber it...
I cannotsay the same thing about factory norma ammo...

So I've gotta ask, what was fired in it?

"Sedate" is a relative thing... the questions is "relative" to what?

I collect and shoot these old guns as a hobby and in all of the time that I have been doing it I have never blown an old rifle with factory or handloads. Simply because I stick to what I believe to be the rules.

The first thing to remember with these ( referring to pre 1898 Mausers) Is that there were no strong Mausers before the model of 1898. The receiver rings were small in diameter but the prime difference lies in the method of breeching. All earlier actions lack the inner stop ring inside the receiver ring. This is the feature which encloses and supports the bolt nose to contribute much of the great strength of the '98 Mauser.

Lets see now about the CZ 52:

The last time I looked the USA was not a signatory of CIP and therefore is under no statuatory obligation to prove that firearms that are imported or firearms that are modified or refurbished comply with some safety standard.

Secondly the CZ 52 was manufactured between 1952 and 56? only and thus as made before the Czech republic became a member country to CIP in 1969.

Here's a quote from Harold McFarland in his book "Introduction to Modern Gunsmithing"

I'm in agreement that pre '98 actions should be used for 45,000 PSI cartridges at the most.

Springfields
..Too many of those military barrels have hidden flaws and defects. They can hold the 30-'06 cartridge and then fail after magnum chambering,costing the shooter some fingers. It is wiser to install a new custom barrel.

Early-Type Mausers
Essentially the same information applies to all the early-type Mausers -The Model 1891 Argentine, Model '94 Swedish, and the models '93 and '95 Spanish. They lack the inner stop ring inside the the receiver ring. This is the feature that encloses and supports the bolt nose, to contribute much of the great strength to the modern Model '98 Mauser. Due to this breeching design, these early Mauser can be considered safe only up to a breech-pressure level of 45,000 p.s.i. They will serve nicely as rough sporters and in calibers such as the 7 by 57 Mauser, 257 Roberts, or .300 Savage. They shouldn't be subjected to greater pressure. The most practical conversion is that which fits a Springfield barrel, then chambers for the .300 Savage cartridge. They will feed and function with this and hold is safely. They can't be considered entirely safe with the additional pressure of the .308 Winchester cartridge. The peep sight which fits on them is the Lyman No. 57 SME.
