I finally have my Husqvarna back from the rebore shop. A dream, with scope and sling right at 7 1/2 pounds. Now for the question, W748 works so well in my 375/06 Ackley, has anyone used it in the 9.3x62? Thanks for any data.

I have always used the Norma factory load of N-201. My buddy uses IMR-4895 and gets the same point of impact. My velocity is about 2300fps with a Nosler partition 286gr. Some people think it's not fast enough but it was adequate to kill everything I ever shot with it.
It will go through a wart hog end to end and also a Kudu. That's good enough for me.

WW 748 should be OK for the 250 grain bullets and possibly the 270 grain Speer bullet. I have had the best luck with RL-15 and Ramshot Big Game with the 286 grain bullet. Those are both a bit slower.
Here is a relative burning rate chart:

I have a couple of kegs of WW 748 laying around and gathering dust. I will try some in my 9.3 x 62 in the spring. Thanks for the idea.

Who did your rebore by the way? Happy with it? Cost?
thanks

The barrel was rebored by Norman Johnson at High Plains Reboring,good jobprice was $230 plus freight. Today went out to the range with a few loads, best group was the 250 Nosler BT with 60gr.H414 and Win. Lrg rifle mag primer it went a little under 3/4", velocity was 2552fps screens 10' from muzzle. Not bad for a random picked load.

I look at the 8mm Mauser, the 338/06, the 35 Whelan as all big .223 family of cartridges....

I shoot the 8mm Mauser and the 338/06....

Any powder that excells in the 223 seems to be excellent in the two above cartridges!

I can just fill my 338/06 to the brim with W 748 and seat a 200 grain bullet and away we go!

No, but I have used H-414 and thats about the same powder with good results...

But bottom line is RL-15 is THE powder for the 9.3x62, nothing else even comes close on the chronograph, nothing!

Just for the record... I think H-414 is about the same powder as W 760, NOT W 748.

W 748 is much closer to Hodgdon BL-C(2), but they are not an exact match.

Using 286 grain Noslers and Lapua brass, 58 grains of Re15 gave me the best all-around load; accuracy and velocity. 4895 came in a close second.

LE270,
That is correct, a brain fart gone south took over, got my powders cross wise, knew better than that, thanks for the heads up.

Ray, what is your R-15 load? I worked up a 286gr Partition load with 58gr of R-15 for my CZ 550. Best I could get on the chrony was 2338. My average velocity for 5 rounds was 2329fps.
My best load for my CZ is 65gr of Ramshot BigGame behind a 286gr Partition. This load will shoot one hole groups and has an avg. velocity of 2424fps.
If you haven't tried BigGame in your 9.3, give it a try, you might just beat R-15 in the velocity dept.

Steve,

I shoow the 58.0 gr RL-15 load in my 9,3x62 CZ 550 American w 286 gr Noslers and get 2425 fps. Shoots about 3/4 MOA, and works very, very well on larger game.

Ray's rifle has a 26" bbl if I remember correctly.
