Does anyone have experience with a 338/376? A search revealed some discussion on this forum about one a couple years ago. 1) How would the performance compare to a 338-06? 2) What work would have to done to a Mauser (VZ-24) action for this round? 3) Would a 338/376 clean up a 338-06 chamber? 4) Any leads on dies or reamers? Thanks! Washougal Chris | ||

1. About the same, maybe a tiny improvment, but not worth the BS. 2. Open bolt face, adjust feed rails, different magazine box? different follower? Feed work can be expensive. 3. No it wouldn't the 376 is short. 4. I think the cartridge you are looking for is the 338 Hawk. A 338-9.3x62 the shoulder is farther forward. The 9.3x64 case the 376 steyr is made for has been shortened. Hell a 338-9.3x64 would be a good cartridge too, but nothing that the 338 Winchester isn't, as the 9.3x64/376 base case is a H&H basic with no belt. | |||

I don't play with wild-cats anymore, they require changing rifles and then having custom dies and other problems. I don't have anything against it, it's just too much work for something I think is supposed to be fun. Here are some factory 323, 338, 358, 364 cartridges that will do similar to what you want. 8mm Remington Magnum, 8x64 (factory 8mm-06), 338 Winchester, 338-06, 350 Remington, 35 Whelan, 358 Norma, 9.3x62, 9.3x64, 9.3x74R for double rifles and single shots, 9.3x70 (more than a 375 H&H). Good luck with your project. I have a few of the ones above. I like them all. | |||

I would argue that it would be a substantial improvement. The only mod is the bolt face. I agree with thr rest. I got tired of wildcats too. FWIW, I am building a 376 Styer on an MCR 1999 Short action, standard bolt face. No rail mods, no mag box mods and no follower mods; just the bolt face. A Mexican Mauser is perfectly sized for 376 based wildcats, too. "Experience" is the only class you take where the exam comes before the lesson. | |||

Im shooting one with a single radius shoulder and abolutely love it so far. There was no hassle or reamer involved...custom body die was not a problem either...Opened up a Redding WinMag seater in the shouler area to handle seating the pills. I'm shooting an Encore which eliminates the bolt face concerns...I am still in the midst of the load dev...but it looks like RL-15 and Varget are working well with the lighter bullets. Will probably hunt with the Barnes 185grn TSX. As it stands now it looks like there will be a slight gain over the -06 based cat. Preformance in the mid WinMag range looks like is where its gonna max out. My chamber is very tight though. | |||

Chris are you trying to change a 338-06 barreled gun or what? I was thinking about this a few times today and I can't think of any reason it's a good idea. 376 brass isn't going to be around forever should be number 1. Regards, Kokdyer | |||

would be about 7.24% more case capacity...6 or 7 gr or so so, yes, it would be a far bit better as it's "olny" to be about 7.5 gr less than a 338 winmag.. since the case is a .500 casehead, it's has more capacity... for example the 376 steyr is about 81 gr of water the 375 whelen is about 74... since i built a steyr on a mexican mauser, i can certainly tell you feeding is a NON issue... open the boltface, polish the ramp a bit, done.. and holds a FIST full of rounds. in fact, if you had the same box with a 338 (assuming 3 down) you could have the 4th one down in a steyr. Steyr brass not around for ever? hardley... is' 9,3x64 basic brass (not 30-06).... and it's CHEAP to buy brass...about 50¢ each delivered from midway.

I believe the case neck is at about 2", right? Depending on what bulelt weights you want to use, it might be worhtwhile to have the reamer cut for a COL of like 3.25" or so. That will allow you to edge closer to the Win Mag and firther from the '06. | |||

Of course 9.3x64 brass will continue to exist, I was talking about specifically marked 376 brass. I am not trying to sound like an elitist snob who doesn't believe in wildcats, but mate I don't get the point. Good luck though, got to be milder than a 338 to shoot and there should be a bit of a boost from a 338-06. Maybe even 338 Hawk (another doggone wildcat). Again Goodluck! | |||

kokdyer, (grin) all in good fun!! I am just laughing with you on your last post, in the wildcats forum quote: As we all know, EVERYTHING started out as a wildcat... 33806, 338x458winmag, 375x64 kurtz, and then 338/375x64 kurtz... jeffe opinions vary band of bubbas and STC hunting Club Information on Ammoguide about the416AR, 458AR, 470AR, 500AR What is an AR round?

Daves gun, .335 OTTR, is a fair amount more than the .338-06 & equals the .338-06 JDJ (60 degree should & short neck) in case capacity. The shoulder/neck junction is right at 2" (actually 2.020) w/ minimal body taper. The sized .335 is .504 at the base tapering to .498 at the shoulder. Total case length is 2.346. This means it would not clean up in a .338-06 chamber. Reamers would have to be made. Work to convert a mauser would be minimal, but like everybody has said, unless you just have to have a wildcat, the .338 WM is probably the way to go. Having said that, I'm having a .335 OTTR built for my encore pistol. The short/fat powder column should make it more efficient in the short barrel of the pistol. | |||

Thanks for all the feedback! I was curious if I could pick up an A&B 338-06 barrel and ream it out to 338/376, but that's not possible. (I already have a 376 Steyr, so I've got brass ready to go.) Still sounds like a good idea - improved performance over 338-06, no feeding issues, minimal bolt face opening - hopefully somebody will order a reamer and let us know! Washougal Chris | |||

The AB barrels I've seen have enough shank to set back far enough to clean up the 338-06 chamber. "Experience" is the only class you take where the exam comes before the lesson. | |||

And it looks like someone over on 24Hourcampfire has ordered a reamer: Short action in 338??? (scroll down to the last post, or search for "Short action in 338???" if the link doesn't work.) And I'd almost talked myself out of the idea. Washougal Chris | |||

don't know about the AB barrels, but the rem or win 338 barrels will definetly work on a samll ring.... hadn't measured a large jeffe opinions vary band of bubbas and STC hunting Club Information on Ammoguide about the416AR, 458AR, 470AR, 500AR What is an AR round?

I am going to have one built on a Mexican and would pitch in on a reamer as Jeffeoso mentioned. Gotta wait a little while until Momma gets over the last project. (416 Aagard on a Mexican) Bob Mehaffey | |||

A&B barels are also available in .338 bore without the pre-chambering. So if you want an inexpensive barrel, you can order one of those and not have to clean up anything. http://www.midwayusa.com/eproductpage.exe/showproduct?saleitemid=311404 My country gal's just a moonshiner's daughter, but I love her still. | |||
