pressure on mauser actions

how much pressure would you feel safe in a columbian fn action?

I would define "safe" as the SAAMI max average pressure for the original chambering, a 7x57 for the Colombian, I believe, which is 46,000 CUP. However, thousands of Mausers have been converted to higher pressure rounds and seem to be working just fine.

a very large number of those rifles were converted to .30-06.....apparantly someone considered them capable of at least that.

A friend used them for magnums a lot.....but that's just one guy!

After being intimidated by Mike the cop, Costello tells, Abbot, "I feel like beating up Mike the cop again."

Abbot asks, "What do you mean, 'AGAIN'?"

Costello answers, "I had this same feeling yesterday."

I rebarelled an FN Colombian to 7x61 S&H and shot it a lot over 24 years then rebarelled it to 404 Jeffery. I have no concerns for my action.

Mr. De Haas in his book "Bolt Action Rifles" articulates a standard I favor. If the gun was made before 1920 or 1930 to be extra safe, restrict it to the cartridges of the era. 7x57. 6.5 Swede. 8x57. Or comparable. .250 Savage. .257 Roberts. Etc. If made after 1930 anything goes. (Except if it is last ditch war time junk...)

As a rule if you take the wood off and look hard at the receiver under the front ring where the barrel screws in you can find a proof date. I have FN's in '06 and .280 and no concerns.luck

On many FNs you can find a Brinell ball imprint on the right hand side of the recoil lug.
