Some datas and readings about the 9,3x62

The thing with RL17 is that there is no reliable book data for its use with the '62 so folks may be reluctant to experiment. My research told me that burning rate is very similar to H4350. So I tried that. Started at 64 gr and went to 67. No conventional pressure sign(primers still rounded and tight, easy extraction, no extracter marks on the brass). But I've also read that pressures can go from ok to 'holy s___" with a small increase and with no warning.

At 67 gr, my velocity was 2454 fps out of a 21" barrel. Recoil was brisk with my 8 lb rifle.

Not much different from my initial experiment with RL-17. From my 22.4" Tikka, I got 2460 fps from 67grs pushing the 286 Hor. At 68grs (last year's hunting load) it was a consistent 2546 - 2549 fps from the 286 Nos Part., with no more pressure signs than 58grs of RL-15 behind the 286 Hornady at 2400.

After bear season/moose season in late November (temps at 0*C), I tried 69grs RL-17 behind the 286 NP at an even 2560 fps. Right now I've some loaded to 69.5 and 70grs behind the 286 NP. Will give them a try when I get an opportunity (after the snow's gone!). So far, my take on RL-17 in the 9.3 X 62 is that it's a tad faster than IMR4350, and that's what the Accurate Powder burning rate chart gives it as well.

I think it is somewhat like IMR4350 in a .30-06. I was told by a good source when I started loading for the .30-06 many, many moons ago, that you could load 'er to the rim, level it with a business card, cram in a 180 and you're good to go! In other words, I doubt you'd be able to get enough RL-17 behind a 286-grainer to cause harm to rifle or self, except possibly to shoulder! Will let ya'll know results... If I survive!

My COL with the 286 NP is 3.36"... not crimped in other words. Your action or chamber may not allow more than about 3.3". Use CAUTION!! Recoil at 2546 to 2560 (286gr) is MORE THAN a .338 WM or .375 H&H in my 7.4 lb (all up - ready to go) TIKKA T3 Lite at 46 - 47 ft-lbs.

If someone wants to read more on the 9.3 X 62, just Google 9.3 X 62 Mauser. You'll get enough reading to keep you busy for a month, though most of it is somewhat dated.

Mauser, that has not been my experience at all with RL17. I find it very linear in pressure signs in 6 or 7 cartridges I've tried it in. In my 9.3-300WM I had no pressure signs to speak of at 3020 FPS with 270 Speers and the next grain just quit going up on the Oehler, nothing radical, slightly more pressure sign but nothing surprising or scary. No where near as touchy as 4320 IME. I've also tried it in the 7-08, 257 Bob, 250 Sav 308, 243, 300 WSM, 260................etc.
 
I've been using BL-C2 in my 9.3x57 and 9.3x62 and I've been very happy with it's performance.

Haven't tried RL-17 in those cartridges yet, but I have found it great in 30-06 - 300 win mag sized cases, and pressure has seemed to go up pretty gradually and predictably.

i just bought a pack of 20 rounds of 293 gr rws ammo and it says out of a 23.5 inch barrel the velocity is @ 2430ft/s. Now that is one hotload.

yes they are a little hot .... what i can say is that that ammo and round is not made for small animal otherwise it will pencil and not expand the TUG or whatever are great but if you choose really the game on it.


they didnt expand on a 45 kgs wild boar but worked great on a 150 kgs. Same for roe deer didn t work but on a mature red deer expand so just my feedback and experience on it.

but what is good with the 9,3s is whatever bullet you pick and choose it will work or mostly.

all the best.

Yah, i wont use it on small game. For that ill use a 140gr 6.5x55. Ill probally use my 9.3x62MM on Moose, elk, caribou in the future. For my all around hunting ill use the speer 270gr bullet @ 2500fts.
 
Is anyone shooting cast in ther 9.3? I tried a post in the reloading section but responses were low. It would seem well suited to cast and a load @ 1600-1800 fps would compare pretty well to the HV .38-55 load for woods walking and practice.

I have zero experience with the 9.3 as my old Husky-FN hasn't arrived yet and I'm just gathering components. Trying to decide between the 270 grain Speer or some 286 Privi loads. Rifle will only be used for black bear and deer at this point so no need for super tough bullets.
 
Over everything written up on the round, there are two authoritative, realistic and wisely put together articles on the 9.3X62 which stand out of the mass; Al Miller's and Ken Water's articles, the first reprinted in "Big Bores Rifles and Cartridges" and the other reprinted in "Pet Loads". These are must read articles and answer most of the questions one may have on the X62. They also are the ones who brang many of us into the X62.

I have read Water's article in my Pet Loads book but not Al Miller's. I always liked Miller's load data and thoughts and found him to provide reasonable advice based on his experience as opposed to just reiterating known loading data. I particularly liked an old article he did on loading the 6.5 Swede. I don't have his 9.3 article but will have to search for it.

I'm leaning towards the Speer 270 grainer as I will only be using it for deer and black bears however the Privi 286 weight might work better with the Husky's open sights. Reloader 15 and 4895 (either IMR or H) are already on my shelf so will likely start with those.

I've shot a grand total of 14 rounds from my '62 using cast 280 gr bullets from The Bullet Barn. Two groups of 3 rounds using SR4729 went into 1.3" and 0.95" at 50 yards.

A third group of 5 went into 1.75" at 50 yds using H4895.

I didn't record any velocities.
 
The 270 gn Speer is my only bullet of choice for my 9.3X62, it's construction is perfectly suited to the velocities and it performs exceptionally, both on light game and heavy boned game. I haven't tried the matrix as I have a good supply of Speers and a very good load both accuracy and velocity wise. I did try the 250 AB but I didn't want to use that light a bullet in the 9.3, the 250 is much better suited to 33 and 35 bore size, likewise I didn't feel the need for 286 or 300 gn as my 37 and 41 bore rifles do this weight range better.
I have only taken one animal with mine, but it was the largest game animal in NA.................Atlantic Walrus. Couldn't ask for better bullet performance, I spined him just back of the head at about 50 mtrs. Recovered bullet showed textbook expansion and weighed about 150 gns IIRC. This would have to be about a worst case scenario for a bullet, impact at virtually muzzle velocity into extremely heavy hide, muscle and bone on a 4000 lb animal, and yet it mushroomed perfectly and retained over 50% of its original weight and the lead core is still welded to the petals, just as Speer advertises. Ted has shot a lot of thinner skinned game with this bullet and doesn't have a bad word to say or a bad experience to relate with the Speer 270 gn. I took a large Yukon moose with one of his 9.3s and a 270 gn Speer, but ended up gutting in the dark so I don't believe we recovered the bullets..........2 shots ......2 hits..........still jumped in the lake to expire, DAMN, cold, dark loooooong, night. Recovering bullets was way down the priority list, at that point.
 
has anyone tried BL C2 powder? hodgon data shows mv at 2548fps and pressure is 47400 cup. it is for 270 speer.
so this power gives 200 fps more speed at a little less pressure.
anyway, I just bought two pounds of it so I will try it.
 
Thanks for the cast and 270 Speer experiences. I've read recently that Ted found the 270 Matrix more accurate but I must admit that it's funny boat tail shape would worry me if it hit heavy bone hard and accuracy is different in every rifle. I have zero experience with it and Ted likes it, so it mist be good. I think that I will get off the fence and order some Speers. I tried Epps today and while they had Speers, they didn't have dies or cases. Too bad Tradeex is down for a few weeks while moving.
