Even my pokey ole 9.3x74R, with 250 gr Accubonds having a .494 BC at 2500 fps can poke a hole in the sky for a pretty long distance with some butt kick left at those ranges!

Any of them will work it is kind of like the 270 win vs 280 Rem debate, people have their favorites and each has it's advantages but in the real world there is no real difference. The 275 gr Woodleigh loads at 2460 fps pretty much matches the 286 gr 9.3mm at around the same speed, the s.d. on them is almost the same so I loaded the Whelen with a similar load with it's 1 in 12 twist.
Doesn't stop thinking about the 9.3x62 :lol: it's a sickness...... :mrgreen:
Jake, you are in a dangerous place, might as well just order up a 9.3mm barrel and get it over with
I agree with Gerry, sounds like your all set to go on this rifle Jake.. That would be a great addition to your family!
As for better than the Whelen..... Well, I will just let that rest. Built up like Gerry's, with a 1-12 twist, there isn't much the 9.3 will do over the Whelen.. I do like the 250 AB the 9.3 guys get to run. That would be an excellent bullet should there ever be a .358 250 AB... I have a rifle I would love to try it in as well!

The 286 gr Partitions shoot pretty accurately in my 9.3x74R at about 2400 fps, with either IMR 4064 or 4350.

That is a pretty stout load Charlie. That really doesn't lag too awfully much behind a 375 H&H. I can see why you all have been so impressed with the 9.3's.
Charlie, what kinda brass do you run in yours? Nosler?
Is the 9.3x74R a 50K PSI cartridge because of the brass or the doubles it used to be chambered in? Just wondering, cause it looks like even at 50K and 2400 it is monster. Should have some excellent case life as well. Pretty interesting stuff.

Scotty, I started with Hornady sale brass and bought 60 cases. Then immediately after that, I found some Norma cases on sale for $40/50 cases and bought 50 of those. The Hornady cases came dented and dinged, plus they have thinner walls. The Norma cases are clean bright and look like quality. The Norma are a little heavier wall thickness than Hornady.
Accuracy wise, I can't tell much difference but I am gong to use Norma because they are a little thicker wall. You probably could go to 60 KSI with the Norma cases in the Number One single shot but the brass is thin and long! Plus I get all that I can handle at 50 KSI, about 35 lbs of recoil with 286 grain bullets. I surely am not going to see anything to shoot in Washington state that needs more Horsepower, even a grizzly. My old and decrepit body does not need more recoil than that anyway!

It is gaining a small, but dedicated following. The move by Ruger may induce a few more to consider the round.

Jake,
What are friends for. Remember friends don't let friends build oh hum rifles. :mrgreen:
Sounds like you are onto something quite worthy buddy.
Looking forward to your build parameters.

So if the 35 Whelen is good to 400yds what would be the max effective range of a 9.3X62?

Scotty, the 9.3x74R trajectory in the No. One Ruger with the 286 gr Partition at 2400 is +2.76 @ 100 yrds, 0.0 @ 200 yards and -10.95 at 300 yrds. Energies are 3657 fp at muzzle, 3150 fp @ 100 yds, 2700 fp @ 200 yds and 2302 fp @ 300 yards, nothing to sniff at. It still has 2000 ft/lbs at 400 yds and is still flying at 1754 fps. Not too shabby for a 276 bullet at 2400.

Well here we go again, with the 62mm case having 10grs more capacity I can see it handling heavier bullets better. Ya I've been reading again and I have to stop that somewhat. I also read about 280gr lead cast paper patched bullets made from wheel weight metal shooting threw 1/4" steel plate at 100yds from a 35 Whelen at 2400fps muzzle velocity. The mind is a dangerous thing with all this available knowledge. :lol: I just have too much free time on my hands with all this cold weather keeping me in the house. :mrgreen:

"The 62 mm case having 10 grs more capacity", than what? The .35 Whelen or the 9.3x74R? Load wise and muzzle velocity-wise, the 9.3x74R and the 9.3x62 are equal (down the road) in bullet weights powders and loads!

Ot3, I read it had more capacity than the standard 35 Whelen. Like I said I've been reading too much and should leave this alone if I'm ever going to finish what I started to do and that is to build a 35 Whelen on a M70 I bought. I'm intrigued by the 9.3X62 and Mikes 9.3X64 and could easily see myself bypassing the Whelen and going with one of these instead, probably the 9.3X64 because of the extra performance it gives. I'm not a magnum junky and to see these older rounds with similar or sometimes better performance makes wonder why they were abandoned for the latest and greatest wonder magnum. I guess I'm a little tooooo old school.Oldtrader3":11jrcijq said:
