Here is my .325 WSM Kimber Montana. I am happy with the say it shoots, and its nice and light for carrying. Only thing I wish was different would be to add a cheekpiece.  | |||

I love the idea of the 8x68S, but I thought it was too long to fit in the Mauser action/magazine box? 3.425 Max cartridge OAL vs 3.315 magazine? | |||

So I was cleaning out the reloading cabinets yesterday. Found a bag full of new Norma Brass. Written on the bag was "30-338". I recall this brass followed me home from a distant past gun show. Pulled one case out of the bag for a closer look. Head stamped 338 Win Mag. But the neck did not look right. The digital caliper said 0.321" inside neck diameter. Hmmm. Necked to 8mm: Now I have a bag of 8mm-338 brass. Interesting possibility. One I have been thinking about is the 8x68S. Another back burner project build will be a Cape Rifle, M98 action, 29 or 30 inch barrel, full complement of iron sighting. A M98 for the South African trade must be in a classic powerful German cartridge, what better than the 8X68S. Harald Wolf had an interesting article in Hatari years ago about Cape Rifles complete with a description of his 8X68S Cape Rifle that he built. | |||

I have been shooting an 8x68S for a couple decades (Commercial Oberndorff M98). All I can say is that I strongly suspect that you would be very pleased. | |||

Does the 8x68S have more power than the 8mm Rem. Mag? | |||
|

The 8mm Rem Mag with edge the 8x68S. But I prefer the 8x68S. | |||

I owned a 8mm Mag, an 8x57, and I've shot a borrowed 8x68...but the 8mm I enjoy the most is my 325 WSM. It was an impulse buy because it was cheap. In 2010, folks were bailing out of guns and the WSM cartridges were plain dirt cheap. I bought a hardly used Kimber 8400 in 325 WSM for $600, put an old Kahles 1.5-6 on it and started playing around. The gun shoots MOA with loads I developed from 160 grains to 220 grains...from 3300fps down to 2800fps. The gun is light...no where near the recoil of the 8mm Mag or 8x68 and is way more capable than the 8x57. Probably like it so much because it works so well and I feel confident with it. Best impulse buy I ever made. | |||

Settled on a 8x68s. Going to do a 6.5x68s barrel for it at well and try to see if a 10x68s wildcat is feasible.

I'd like to add a plug for the 8X64S (otherwise known as the 8mm-'06). I have a BRNO ZG-47 in that caliber and as a companion a Krieghoff drilling in 16/70-8X65RS. I'm not shooting anything bigger or more dangerous than a white tail these days, but both weapons speak with great authority and are very pleasant to shoot, with low noise level and recoil. I have a couple of 8X68S's, as well as 8X57I and IS and 8X60S, but I believe the 8X64S suits me best. Brass is easy to make from .30-'06 cases and for the 8X65RS, from 7X65R cases (the rifle barrels were both rebored from 7mm). Just about any load shoots well. | |||

If you load them to the same pressure, in the same length actin, there won't be much difference in MV. Not enough to justify the increased muzzle blast and recoil IMO. GOOGLE HOTLINK FIX FOR BLOCKED PHOTOBUCKET IMAGES https://chrome.google.com/webs...inkfix=1516144253810 | |||

I have an HS Precision in 325 WSM if interested, as well as a bunch of cases, bullets, ammo, dies, etc. I've got several 338-type rifles, so one could go. | |||

Parker Hale used to make up rifles with ZG47 actions. Got one in excellent condition at an auction for $500. Complete rifle, 30-06. Maybe I slap another Mauser action in place of the ZG47 because the rifle is in great shape.

A couple comments about the 8mm's that I have experience with. I have an 8x52 in a Siamese mauser,several 8x57, 8mm-06, 8mm-06 Ackley improved,8x68,8mm-338, 8mm Rem mag and an 8mm Mazon which is the 9.3x64 case necked to 8mm. Of the smaller 8mm's the 8mm-06 Ackley is a very good round. The 8mm Rem will best the other 8mm's I have by close to 100 fps. The only bullets I've used, that hold together at top vel are the Barnes TSX 200 gr, Partition 200 gr or the Swift A-frame. The 8x68 and the 8mm-338 have the same case capacity and deliver the same ballistics (75 to 100 fps slower than my 8mm Rem. The 8mm Mazon case capacity is a couple grs smaller than the 8x68 but velocities are very close. Tha Mazon has a 4mm shorter case so bullets do not have to be seated so deep in a mauser action. If I could only have one 8mm rifle it would be a tough choice between the 8mm Mazon or the 8x68. I would have to look long and hard at the 8mm-375 Ruger as well. I see little to be gained by going to a case with more capacity than the 8mm Rem. But whatever floats your boat. | |||

Have you tried any 220 gr bullets in the 8x68? Specifically the Woodleigh PP and Sierra Game King (made from the 8mm Rem)? Or even the 200 gr PP? I use a 200 gr AB in my 8x57. I think it might be a tad soft at under 200 yards and over expand? It's a smasher a 2,450 fps in my 8x57 within 300 yards - quartered a red staff at a severe angle - entrance ahead of left rear hip, through heart, lung, and right shoulder at 250 yards. Not bad performance for a 8x57. "Evil is powerless if the good are unafraid" -- Ronald Reagan "Ignorance of The People gives strength to totalitarians." Want to make just about anything work better?

I load my 8x57IS to 2700 fps with Speer 200 gr Hotcors and Rl-17. My 8mm-06 Ackley hurls the same bullet at 2900 fps with Norma MRP. Both are compressed load that are at or under 60K chamber pressure according to QL and pressure indicators.. Either will speak with authority without excessive recoil or muzzle blast.There's a quick snippet of the 8mm-06 A.I. hitting a watermelon at 100 yds at the end of this video clip. https://www.youtube.com/watch?v=UvT1Po5ReUE GOOGLE HOTLINK FIX FOR BLOCKED PHOTOBUCKET IMAGES https://chrome.google.com/webs...inkfix=1516144253810 | |||

Wildcat Junkie: You make reference to the pressure predictions you get from QuickLoad. What experience and insights can anyone offer about using QL? Does anyone use the Pressure Trace II system? This should be new topic, methinks. | |||

Austin Hunter I have used the 220 gr Hornady and the 220 gr Sierra. I found the Hornady did not hold together very well on moose. The Sierra was a little better but still not what I wanted. I found the 200 gr TSX and 200 gr Partitions both penetrated much better @ 8mm Rem velocities. Meant to try some A-Frames and some Woodliegh's but never got around to it. | |||

Do you mind sharing your 200g NAB load? I'm looking for an alternative to the Woodleighs as they wont group in my rifle at this stage but was under the impression the NAB was too stout for the x57 Formerly Gun Barrel Ecologist | |||

That word "Ultimate", opened a big ole can of worms, and all common since goest South at that point...The ballistic tables may be a better source to reach your goal!!  I like the 8x60S, only because I have one, but my favorite 8mm caliber is the 8x57 why that is I have no idea..I think I just like the gun itself better...

Settled on a 8x68s. I bought a near mint condition Parker-Hale Hussar in 30/06 built on a ZG47 action for under $600. Starting soon! 26" barrel, front sight and detachable peep sight, no rear sights on barrel at this point. Getting a great piece of Turkish walnut for the stock. Got a S&B 3-12x42 illuminated scope on sale at Eurooptic for $1,065!!!! Thinking about having the front sight be a banded setup and installed a barrel profiled thread protector so I can install a suppressor, but have it look standard without it installed.

Good decision IMO. You can take a mill file to the back of the magazine box and thin it down to .060". That will gain about .060" on average. The front can be thinned above the hinge line by another .060" or so. Stay about 1/8" above the bottom to keep strength and avoid the necessity of welding a plate at the front. It doesn't matter if the bottom opening is slightly shorter than the cartridges as the bullets tips will be above that area and the cartidges will fall out tilting down from the rear when the floorplate is swung open, clearing the front edge. It also doesn't matter if you mill through the center slot for the front hinge boss as the cartridge tips will contact the front of the magazine further out towards the edge of the box. That should gain enough for the 3.425" CIP standard COAL for the 8X68S. My 1904 Portuguese Vergueiro bottom metal is 4.550" inside length using the above methods. You will most likely have to take some material from the bottom of the feed ramp to keep the edge of the feed ramp forward of the front magazine wall inside edge. I am loading my 8mm-06 A.I. to 3.415" and the magazine swallows them up easily with room to spare..

I want to go for 3.5"+ so this is good news. Want to seat long to optimize powder. Going to try 200 gr Accubonds (what I used in my 8x57), 200 gr TSXs, and 220 gr Game Kings.
