Your friend is incorrect. There are many people who jump to conclusions as to action strength without thinking their statements through very well.

The original 9.3x57 round does not have a CIP nor SAAMI standard, however Norma loads the round to a low 34,000 or 35,000PSI - this is not an accurate indicator for action strength, as they seem to think. I suspect, due to the waining popularity of this ctg. in Europe, they do not feel compelled to boost their medocre ballistics they have unilaterally chosen for the round. As to possibly stretching or cracking the actions, overload any action and problems will happen.

That model Husqvarna is also chambered for the 8x57 and 9.3x62 rounds, which have a CIP pressure limits of 57,000PSI. If you check the sites where these rifles are being sold by the hundreds, you'll also find them barreled and chambered for the .30/06 round, which has a SAAMI max of 60,000PSI and the CIP max of 59,000PSI.

I have to wonder what criteria your friend used to assume the action was not suitable for the 9.3x57? Just because it is an old action? Doesn't meet the stats nor the ctg. also chambered for it.

Usually I am a speed demon, however in my own 9.3x57, I'm just find with loading 270gr. Speers to 2,300fps with 48.6gr. H4895 or 53.0gr. BLC2. I use 50.0gr. BLC2 or 45.0gr. H4895 with 286gr. Normas, 285gr. Privi's or 293gr. for 2,200fps as well as 45.0gr. H4895 with 300gr. sized down Hornady's for 2,175fps. There are NO indicated pressure signs with these loads - primers are just as round just as when they were loaded, and the only way we have of accurately judging pressures, measurements, virtually no expansion.

Please note that 1923 era 9.3x62 amo was loaded with softs and solids in 286gr., at 2,175fps. That is the load John Taylor was so enamoured with and noted the speed did not have to be increased to 2,340fps as happened a few years later.

232gr. Vulcan or Oryx, if driven by 56.0gr. BLC2 or 52.0gr. H4895 can achieve 2,450fps in the 9.3x57 as well as a sized down 225gr. Hornady, same load gets 2,550fps.

All of these loads shoot into less than 1 inch @ 100meters in my 1929 M46 Husky, with the M94/M96 action.

The heavy bullets shoot cloverleafs, btw.

As to case expansion as the web - (not the head where there is NONE, nor can there be any allowed), mine run .0001" to .0002" - at the web with these loads, after being sized in my Hornady dies. Yes - only 1 to 2 ten-thousandth's of an inch, not .002, .005' or whatever which is normal for most ctgs and rifles. What are the pressures generated, I don't know, but do know without a doubt, they are safe in my rifle and good enough I do not need to increase them. If I want more power, I have a 9.3x62 that gets 2,520fps with 286's and 2,675fps with 270's, which is probably WAY to fast for the Speer bullet.

BLC2 is an exceptional powder for this round (and the 9.3x62), as-is H4895 and Varget. Varget, being slightly slower, usually needs another gr. weight to duplicate my H4895 loads.

IMR 4895 is NOT the same as H4895.

As ALWAYS start 5% LOWER THAN ANY PUBLISHED LOADS and work as pressure signs indicate.
