I have heard of these two quite a bit here, and looked them up in the COTW book. The 9.2x62, if I'm not mistaken, is based on a case simular to the '06, where as the 9.3x64 is slightly fatter, and produces high velocity/power. Now, with the 9.3x62 being slightly smaller and weaker, why is it considered a buffalo cartridge? Isn't this one simular to a 35 Whn, only with a slightly fatter bullet? Wouldn't the 9.3x64 be better? Please shed some light on this. ~~~Suluuq | ||

The 62mm is similar to a .35 Whelan Ackley improved. It uses a standard blotface and has been in worldwide use for the past 100 years. There is plenty of factory ammo available, though not much is being imported into the US. Handloaders can reach .375 H&H ballistics. The 64mm is a Brenneke cartridge designed to rival the .375 H&H. It does not use a standard or magnum boltface. It never achieved the popularity it deserved and ammunition is very scarce. Since the velocity difference in only about 100fps, most folks opt for the 62mm because of its popularity. You can contact me a stutzenrifles@aol.com for some interesting web sites on this. ------------------ | |||

That 9.3x64 is a very nice case . Too bad it isn't popular enough to make it a viable choice ......... | |||

Thanks for the info. I don't understand something... how can the 9.3 be compared to the 35 Whn "AI"? Aren't they basically the same case/capacity? Given the 9.3 may come within 100 FPS of H&H, can I assume the 35 Whn might as well? I'm not trying to go against the 9.3, I'm only trying to understand it. Thanks. BTW I did notice today, in the Midway catalog, they offer 9.3x62 dies and brass. ~~~Suluuq | |||

This is where we get involved with political science. The only reason the .35 Whelan was even invented was because post WWI isolationism and anti-German sediment prevented the 9.3x62 from becoming popular in the U.S. It probably is the most efficient cartridge ever invented, but it wasn't American. The .35 Whelan AI is an attempt to reinvent the 9.3, but it has slightly less case capacity. The slighlty smaller bore also creates less of an expansion ratio for the burning powder. The .35 cannot match the 9.3's peak performance, just as the 9.3 can't match the .375 H&H's peak performance. It's all physics, I think. http://www.hunters.com/africanhunter/rifels.htm#part2 ------------------ | |||

I doubt the inventers of the Whelen were worried about "copying" Euro rounds one way or the other. Americans, being a practical sort , made the best of what was readily available to them . They had access to a good number of 35 caliber bullets because of other American 35 cartridges . They had a plentiful supply of 06 cases . A need existed for a good medium bore cartridge that would feed nicely thru the Springfield action , and would outperform the 06 on heavy game . Thus the Whelen was born , a simple necking job and you were in business . No fuss , no muss , and no ordering or waiting for expensive components from overseas ........ | |||

The 9.3X64 is a serious cartridge. With 300 gr bullets it will surpass the 375 H&H by a bit and with 250 gr bullets will match a 340 WBY or .338 RUM. Brass is a problem, but not insurmountable. You can build one easily on a stock M98 action and have a very serious gun for very little money. I'd rather have a .35 Whelan ,however than a 9.3X62.-Rob | |||

quote: Suluuq, the 9.3X62 is on the -06 case, or rather the lengthened 7X57, but the shoulder is farther forward then an -06, so a little bit more case capacity, thus folks associating it with the 35 whelen ackley. As far as why the 9.3X62 is considered a buff round, and the 35 whelen not, it comes down to beuracratic rules. My personal thought is, prudent minimum for thick skinned dangerous game is 40 caliber, 400 gr @ 2200 fps. The bore on the 9.3 is .366" vs .358" for the whelen. The std bullet weight for the 9.3 is 286 gr, vs 250 gr for the whelen. In reality, with similar bullets, the rounds are indistinguishable. If one says a 35 whelen with a 280 gr a-frame isn't a buff round, then neither is the 9.3X62! | |||

The 9,3*62 was developed 1905 by an German Gunsmith called Otto Bock, who lived in Berlin. The cartridge became very popular the last years overhere. A friend of mine take�s all of his game with it, and it gives him excellent performance, even the circumstances are not so good, e.g. we shoot all our boar�s during the moon periods by night. He shoots roe�s, wild boars, fallows and red�s whith his 9,3*62 (approx. 5 red�s, 20 fallows and 60 wild boars per year). The 9,3*62 was developed for the german colonies in africa. It�s "low-pressure" cartridge compared to the 9,3*64. The last named 9,3 is known for her kicking, while shooting it. The .375H&H is more comfortable to shoot and even the spread of available bullets is much bigger and maybe cheaper. If u guy�s need brasses, projectiles or anything like this for u�r 9,3*xx or 9,3*xxR....i can give u some adresses or links where u can order online. Brasses: i would take the one from NORMA . They are as good as the RWS Brasses ( RWS bought NORMA and i think all the RWS brasses are produced by Norma but only get the RWS stamp instead of the Norma). by the way what is the explanation of IMHO??? Hope this helps | ||

I am new to the 9.3 x 62. Just bought a beautiful custom Husky in this caliber. So far only trips to the range shooting Norma factory 286 grn ammo. I have never owned a 35 W but do shoot a 30/06 AI. Now, I am going to Africa again in May. This time I was going to take my 338 Win Mag until I got this 9.3 x 62. The 338 with factory 225 grn ammo beats the hell out of me and the 9.3 with factory 286 is a pleasure to shoot. Laws of physics say I should be getting more recoil from the 9.3. Maybe in measured ft. lbs. that is so but in felt recoil..no way. 9.3 groups better in this case so guess what is going to Africa with me this time. I think the best explanation of a 9.3 was by someone on this forum or HA who wrote and said the 9.3 does a quart size job from a pint size bottle. Rather than try an figure out what it is or isn't...that pretty much describes it for me. Everyone I have talked with that has taken game with it has only positive things to say about it. When I told my PH I was bringing it he just smiled real big and told me all the things he has killed with one though the years. He is most pleased I am showing up with one. I think I am going to be most happy with this caliber and I wish now I would have found it much earlier in my hunting career. I would almost bet the 338 is going on the auction block...this will be my "in between' rifle between my 30/06 and my 416 RM if it all goes as I think it will. I still want a 35 W but...in a Rem. pump. | ||
