9.3x62 hot loads

freire said:
I haven't checked the velocity on my load for the x62, but 285 grains pushed by 59.5 grais of varget isn't pleasant at all.

That is a stout load. I use a 250gn bullet over top of 60.5gn Varget, I can only imagine a 285 with nearly the same powder charge.

With hot loads, that rifle will pound you. However, the FN98 is the bettter choice.

i had one in T3 Tikka, an laoded with 250gr hot loads it was a handful..... so much so i never tried the 232gr as it was just not my cup of tea.. my heavy Ruger on the other hand.... doesnt mind it

I think mine is a 649 and I get around 2450fps with 286gn Aframe and I wouldn’t want anymore, plenty of a killer and enough but not too much recoil! I have a 9.3x74r coming( end of the month supposedly) and I’m hoping to keep it at around 2350fps with same weight bullets!

Mine is a true Mauser 98 Husky and weighs 7lb 15oz fully loaded. With a 286 gr bullet at 2350 it is plenty of rifle...for sure off the bench. Another hundred feet per second is definitely not what I'm looking for!

If memory serves, my load is 62.5gr of RL15 with a 286gr bullet. Off your hind legs it's not bad, in fact very few are. But off the bench that thing is a handful. Up around 40 lb-ft of recoil which will get your attention in a hurry, especially if you're a "squeeze the rear bag" kind of bench shooter!

I hear yea, these 9.3 cartridges are no laughing matter, they have some serious recoil.
 
There was an article some years ago by John Barsness - he owned or noticed that CZ made same rifle chambered in both 9.3x62 and 30-06 - could not come up with reason why pressure levels had to be different in identical rifles. He made up some loads and went to Western Powders lab in Montana to verify pressures - not sure which ones he checked there. He had his buddy test them on a Pressure Trace "strain gauge" to compare to Norma ammo - he wrote that none of his loads exceed 60,000 psi, which is the SAAMI limit for 30-06. He published various loads - "Big Book of Gun Gack" - p. 391 - 60.5 grains Varget and 62.0 RL-15 with 250 grain Accubond bullets (circa 2,650 fps); 66.0 grains Big Game with 286 grain Partition bullet (circa 2,475 fps) - was close to 30-06 pressures, which is more that 9.3x62 pressure limits. CZ 550 9.3x62 rifle with 23.6 inch barrel - Norma cases and CCI 200 primers.

As per his article, original 9.3x62 bullets were 18.5 gram (285.5 grains) at about 2,150 fps. He says after WWI, that better powders allowed velocity increase to circa 2,360 fps for those 18.5 gram bullets.

Did you ever clock that load by chance?
 
So what is a "hot load" and "higher chamber pressures"? I guess we can assume it's 60K psi - the same as the 30-06, that has essentially the same base diameter as the 9.3X62, within a few %.

We're very good at not answering simple questions, and if you let a thread run long enough on CGN, someone will suggest you buy a 30-06. Hasn't happened - yet.

Despite people telling you that the 9.3X62 was "not designed for 60K psi" or that you should buy another gun, all three of those guns can safely handle 60K psi with a 9.3X62.

SAAMI Standards Z299-4 - SAAMI explains their pressure test terms on pages 8 and 9 - Go to page 24 - their "limits" for 9.3x62 are Maximum Average Pressure (MAP) at 57,500 psi; Maximum Probable Lot Mean (MPLM) at 59,000 psi and Maximum Probable Sample Mean (MPSM) at 61,200 psi, as per their piezo test procedure - SAAMI has not set CUP limits for that cartridge. For 30-06 (page 29), their piezo limits are MAP at 60,000 psi, MPLM at 61,500 psi and MPSM at 63,800 psi. If you want - page 28 - 270 Winchester - MAP is 65,000 psi, MPLM is 66,600 psi and MPSM is 69,100 psi.

I've a Husqvarna M98 in 9.3x57, it really starts to buck with brisk loads and the factory buttplate, the x62 in that rifle would be too much of a good thing for my taste.

Hello
I am looking to add a 9.3x62 to my collection, and am wondering what action would handle higher chamber pressures. A Husqvarna FN98, A Husqvarna 1640, or a carl gustaf 3000. Thank you

Of the three actions you mention, the first two would definitely be just fine for higher-pressure 9.3x62 loads. And the CG 3000 (Sauer 80 action) would probably be OK too, although I'd probably want to keep pressures lower with that action to avoid case stretching (and possibly difficult extraction) with its rear-locking feature.

Andy has worked up a pile of loads for this and posted velocity in the reloading thread a while back.
Very knowledgable fellow nut, always safe and very handy. One of my 9.3x62 is a FN98 he reamed out himself from a funky Tradex HVA 9.3x57.
I reworked the comb a bit, not much of a recoil pad, but this thing shoots...sub MOA.

This cartridge was designed in 1902... unless you are going to load to the point of case failure those actions will suffice.

If you are going to load so hot as to induce case failures, use a Remington 700 made for the 30-06 cartridge. It is the strongest, safest 2 locking lug action ever made. It will contain case failures better than any other 2 lug bolt action.

I think the 9.3 x 62 would be rather hard to over load to failure but it is possible.

My rifle is light, my shoulder would fail first. LMAO.
