9.3x62

[DrMike]

Rodger,

I built my 9.3X64 on a Winchester action. It delivers accuracy and is comfortable to shoot.





Well, you already have the donor. The reaming is not a particular difficult job for the LA Winchester and a standard bolt face such as you already have.

 

[truck driver]

Sorry Boomer for stealing your post and getting side tracked. You picked up a very nice rifle.
Now back to my Buddy Dr Mike, just how comfortable to shoot is the 9.3X64 say compared to a 300Wby, more or less recoil?

 

[DrMike]

More of a shove than a slam. I don't fine the recoil objectionable at all.

 

[gerry]

I'm not sure which round you were referring to when it comes to case capacity Nosler states this in their on line manual and 250 gr bullets with all 4 rounds using water.

35 Whelen - 62.2 gr
9.3x62 - 62.5 gr
9.3x74 - 68.5 gr
9.3x64 - 73 gr

I'm not sure which round you were referring to when it comes to case capacity Nosler states this in their on line manual and 250 gr bullets with all 4 rounds using water.

35 Whelen - 62.2 gr
9.3x62 - 62.5 gr
9.3x74 - 68.5 gr
9.3x64 - 73 gr

Yeah, the 9.3x62 has a little more fuel room than a Whelen.

Here is what QL shows for SAAMI H20 capacities.

9.3x64 Brenneke 88 grains
9.3x74R 83 grains
9.3x62 78 grains
35 Whelen 70 grains

Here is a look with 250 grain Noslers.. I used powders in each that that looks pretty good, maybe not the best, but they look good, just to give an idea of what they all run with the same bullet weight. The 9.3's pull ahead a little bit more with heavier bullets due to the larger bore size, but the 9.3x62, 9.3x74R and 35 Whelen all seem like birds of the same color. The Brenneke is a beast. That cartridge looks really impressive with heavy bullets..

[DrMike]

Any one of those loads will deliver a tremendous "whomp" on game.

 

[Oldtrader3]

It is pretty strange that these .366 inch calibers nearly became extinct after their introductions in 1905 or so? They do have "whomp" and staying power for moose and even elk, despite drop figures at longer ranges. The 250 gr AccuBond has kind of breathed some life back into these old medium bores. I am glad to see it. They are quite capable cartridges in their own right.

 

[JD338]

Roger,

Recoil from these classic rounds is more of a shove than a jab.
Most 30 cal and up magnums with MV in the 3000 fps and up range have the jet effect,
meaning they come back had and FAST.

Put a good recoil pad like a Pachmayr Decelerator pad on your rifle and a 35 Whelen class cartridge
is pretty easy to shoot from the bench. In the field, you will never notice it.
You can also not worry about having to use hearing protection when hunting with these rounds too.

Scotty, This is the web sight I got my info from ( outdoorsdirectory,com/showthread.php/125255-35-whelen-vs-9-3x62/page2 ) (or just google 9.3X62 and click on link) article #28 A fellow named Mainer in AK is the author of this reply to another post. He also states in other replies that he favors the 9.3X62 over the 35 Whelen and claims similarity to the 375 H&H which I was skeptical about. The 9.3X64 Brenneke ya I can see the comparison to the 375 H&H from what I read on Wikipedia. Is it any wonder I get confused if these guys are posting false info.

 

[SJB358]

Well, similar is relative I guess. I don't think he is wrong, cause a 286 PT at 2400 is pretty similar to a 300 PT at 2500, at least in my book.. Especially when you consider the 9.3x62 is probably doing that work with a little less powder in a little lighter rifle and probably a touch shorter barrel.

Sometimes you just gotta go with what you want. Heck, Gerry is doing 2400 pretty easily with the 275 grain bullets in his Whelen. All in all, they are all very much the same unless your hunting something very dangerous. Then, I know the 375 and 9.3B are better on paper, but it still takes some piloting to make the better come out on game.

 

[truck driver]

Ot3 from what I read at Wikipedia the destruction of the Mauser rifle factories in Germany is what almost doomed the 9.3 and other cartridges like it along with the decolonization of Africa forcing the European farmers out caused a lack for supply and demand.

 

[truck driver]

I think I understand what your saying Scotty. The possibilities of me running up against a Grizzly or Big Brown which they say are one in the same are slim and none but you never know. If I get a chance to fish in BC I think I will have a fast handling 12ga with 1oz solid slugs like the old hour glass sabots that Fed and Win made which I still have several boxes of.
Mainer in AK is also the one who claims the 9.3X62 brass capacity is 10grs more than a 35 Whelen.

 

[Oldtrader3]

Ot3 from what I read at Wikipedia the destruction of the Mauser rifle factories in Germany is what almost doomed the 9.3 and other cartridges like it along with the decolonization of Africa forcing the European farmers out caused a lack for supply and demand.

Yea, we did not pick up on much of what was going on in Europe and Africa prior to WWII, especially in G. S. W. Africa. The smaller factories like Heym & Sonn. took a long time to recover and be allowed to produce sporting arms again under the terms of Occupation until 1964, or they never did recover.

 

[truck driver]

This has been a lot of fun but after all the research I can't see a 9.3X64B in my future, just too hard and expensive to find brass for but there is a possibility for a 9.3X62.
I also read where the Russians were working on a 9.3X64 Sniper round for Urban Warfare back in or around 2000.

 

[gerry]

Yes brass is a bit tougher to get and expensive for the 9.3x64 but it is a great cartridge. It was probably easier at one time to find 35 Whelen brass but now it is just about as easy to find the 9.3x62.

 

[truck driver]

Actually there is more 9.3X62 available then 35 Whelen and cheaper Gerry. Norma is one that I found that is cheaper than their Whelen brass. I found some real cheap stuff made by Privi but I don't know how good it is.
I would also have to have the bolt face opened up to except the 64B and maybe the rails to accommodate the fatter brass or find a magnum donor like my Wby Vanguard which could be a possibility also since I'm not really fond of that cartridge at least not off the bench.

 

[Blkram]

9.3 x 62...been dreaming of one for awhile.
I've shot Dr. Mike's Brenneke and found it pleasant to shoot, but have had my heart set on the 62 version for quite some time. Besides, I wouldn't want the exact same thing as the good Dr, now would I?!?
I do have a 338-06 that I like a lot, but want to pair a 6.5 x 55 with the 9.3 x 62. A pair of matching left handed Sakos would be very nice!
And there is a bit of family history there, since John Barsness wrote the introduction to the cartridge in the Nosler Reloading Guide 6; my Dad was his Cree Guide that summed up the 9.3 x 62's virtues so eloquently..."it kills quick and doesn't shoot up any meat!"

 

[DrMike]

Well, I wondered how long it would take for you to show up. I'll try to get the word out for people not to listen to you. Nothing but trouble here, people. Watch out for "Cloud Buster" (ask me later about this). Good to see you finally made it, Gil. :grin:

That's "Sky Hunter" to you!
