With all the hoopla over the 9.3X62 and the 338-06,etc., here on the forum for the last year or so, I was just wondering if someone has already tried a 338WM case necked up to a 9.3mm? Or is it too close to the 375 Taylor? If anyone has, what were the results?

9.3 x 300 win mag would be interesting as well. I tend to use more than enough gun | |||

Guess it would depend on what advantage you saw in a .366 vs .375 dia bullet. At equal weight the 366 would have a slightly higher BC. Based on the limited gain between a 375 Taylor and 375H&H I can't see how the slight difference in the 338 & 300wmag case would get you much. For my $ a 375Taylor with a 260 accubond would be hard to beat by anything in .366. Then again there are starting to be more .366 bullets on the market. A 9.3x338 wildcat would be just like many of the other 100s of wildcats on the market. Yes it would be different but what would you really gain over what is out there? Volume wise it is basically the 9.3x64 which gives you around 100fps over a 9.3x62. So I guess you have a 9.3x64 with easier to find brass. As usual just my $.02 Paul K | |||

That's a good description. Case capacity is real close. My 9.3x338 shoots 250gr Accubonds over 2800fps with RL15. I'm using 250gr TSX bullets now, havent cronographed them, but they are super accurate. I like the cartridge a lot. I've been trying to get it bedded into a McMillan stock, but ran into some gunsmith glitches. BTW, if considering the 300WM case, check the cartridge overall length first to make sure it fits in the magazine and feeds well. My Ruger action required no modifications for fit and feed with the 338 brass as parent. The 9.3 bullets normally seat out further than the 308 bullets in the 300 mag, which will result in a significant increase in cartridge OAL.

The 9.3 - 338 WM is also called " 366 Alaskan" | |||

Kablewey had "The 9.3-338WM is also called "366 Alaskan" stamped on his barrel and then had a .22 sleeve installed in it and converted it to .223 so that he would have something he could use. | |||

Funny.  Hey, cm, you shared the results of your internet research with us, in another post. Let me share my research as well. I have discovered the miracle cure for the 223 affliction. It's a brand new discovery, and goes by the name of Trollobotomy. Look it up in the medical research. It's right there along with stiffareena.  The first is a surgical procedure, and the second is easier and comes in a little blue pill. KB

C'mon KB. You have to admit that was funny. It gave me a much needed laugh for the day.   I myself, just went with the Brenneke. Figured it was appropriate for the Mauser actions I put them in. | |||

I think that you will find that is called a 9.3 USA. It holds 88.3 of H2o 9.3x64 is 84.8 and a 9.3x62 is 75.8 grs of H20. | |||

The 9,3x64 is actually 200-250 fps over the x62. The x62 is typically 2350-2400 fps with the 286gr, and the x64 is 2600-2700 fps. m | |||

M For factory ammo I bet you are correct. I've never loaded for the 9.3x64 however loading for the 9.3x62 I was easy 2550+. But I wasn't loading to the 56565 limit of the factory ammo. Probably 200fps advantage to the 9.3x64 even handloads is a better guess. As usual just my $.02 Paul K | |||

I have one rechambered to 9.3x338 with "Specially made for Chas. A. Heyer and Co. Nairobi". I'm not looking at it so excuse the spelling. It shoots 10 rnds. in 1/12 at 100.Type A action.Somebody drilled and tapped the 1915 action so it has a scope now.So the collector value is lower. Damn sure shoots though. Takin' it to Namibia next time. | |||

I have also made a 9.3mm-338. I had the shoulder angle changed to 35degrees and a long lead in to accmondate barnes 286gr with .050 to lands. Overall cartridge length is 3.6"+. The rifle is a Blaser R8 on a carbon fiber stock and a vias micro brake. Overall barrel length is 20" counting brake(actual barrel 18.5). twist 1:12.Total rifle weight including the Trijicon RMR is 6LB total length of rifle 36.5". Muzzle velocity is 2600 fps with the barnes 286 tsx using RL-15. It shoots like a charm - recoil suprisingly is pleasant and the Vias brake diverts the sound forward so noise is not what you'd think. Also it is accurate less than 1/2 Moa. | |||

When I first built my 9.3x64 rifle I had very little RWS brass so I made some from Win belted cases. 338 or 458 both work. A little machining on the lathe size and load. The cases I made from Win brass have the exact capacity as the RWS brass.Likely easier to go with the 9.3/338. Either way its 375 H&H performance out of a std length cartridge | |||

Ive always wanted to do just that, but I always just got a 9.3x64, its just a better cartridge case any way you cut it and components are to be had. If push comes to shove the 9.3x64 is the best all around cartridge ever, IMO better than the 375 H&H and that is high praise! A 9.3x 338 would, in effect, be 9.3 Chatfield Taylor, not bad...

I think another interesting project would be to make the 9.3 using the 375 Ruger case - seems pretty natural. I did the 338 primarily because I had over a 1000 cases of 338WM and 358 Norma Magnum brass and know its not so popular these days but I personally favor belted cartridges. Its fun to hear what works for others | |||

I have pushed on Norma before to come out with a 9.3 Norma Mag based off of the 358 Norma. I am back from a long Hiatus... or whatever. Take care. smallfry | |||
