Cutting Coins

As I am not a guru of anything, and members of my old gun crowd are dead or displaced, I have written to a number of sources to find out how much pressure a mauser bolt action can take before the reciever is junk.

I doubt Ruger releases that information.

Yes, blow the reciever. On some mauser derivatives, the bolt will be history much sooner than on others, Remington vs Ruger, for instance. Ruger should outlast all of them, I'd guess, it's not really fair to compare 50 year old Nazi 98's to recent production.

Anyway, I'm guessing over 120,000 psi,well over in many cases.


A guy came in to the gun shop I used to manage and had part of a finger missing. The reciever bulged and the bolt was history. He'd followed book on the 35 Whelen, ( and I had friends who vouched for him) but the Barnes bullets of that period were somewhat known for being over diameter on a random basis. Barnes denied this. A friend of mine miked the box and found over diameter bullets. This situation, if it existed, appears not to exist today. (notice my legalese?)

I recall his load was warm, but not scalding. Thing is, Mausers were made by different people at different times, and who knows what has happened to them before the guy today rebarreled it. What are his throat and headspace dimensions?

Some rifles had incomplete or too hard heat treatment, the steel varied, and the captured and enslaved workers had every reason not to turn out great rifles for the Nazi's. I bet it was more his particular rifle.

anyway, I want to know how far Ruger et al tests and what is the destruction point.

For sure Ruger is going to be one of the last rifles to blow. At the same time things happen even in the best of factories.
You might check with Peterson Publishing. Their writers have tested almost every gun you can imagine.
Another source of information on such things might be H.P. White Laboratories. They used to test all kinds of loads for the wild cats and still do I"m pretty sure. A google search might turn up something too.
 
That's the one, Pappy; I kept looking under 'white'.

I know they tested the cylinder strength of the Ruger single and double actions.

pistols are pretty cool, too. I've got the Ruger P90 DC in .45 Nice smooth firing, light for a larger frame gun, wide ejection port and trigger guard (for firing with gloves on).

Ferrous, what is your moniker in the hunting and shooting forum on About?

The problem with the Ruger, if it is one, is the 7 round mag. If I want a 7 round mag, I'll get a 1911. Ten is the magic number for anything else, which must try harder to win my dollar from the Browning design nearly a century ago.

HP White lists and explains the criteria for testing, but not client's results. ( that I could see) I suppose Remington really doesn't want to be compared to Ruger.

I posted the question in the Hunting and Shooting Forum on About, but the host didn't know any more than I did, and thought too, overloads in the mauser design usually just vents the gas out. A brass cartridge case fails before steel.

I wish I had an antique Colt 38, but I'm glad I don't have to work on one if it breaks.
