HI Doug
could that case be the same as the mach 3 case I am not sure just asking as far as bench quality I am sure there are a few good ones the ppc for sure is a good one but all of a sudden the 6 284 has hit the scene and it is a winning case same with the 6.5 I still beleave a lot of the old bad fouling storys and this and that about the 17 is still out there and still yet there is the group that anything over the 17 rem or mach 4 is an overbore case. I just got the packege from ben with the 17-225 Info and a loaded and formed round it is a preaty nifty case he also sent me a pea we case too.I bleave that the old 17-222mag would work for bench rest shooting is it a 1000 yard rifle no but at onehundred and twohundred yards it is a real challange to the larger rifles now I will hear all the naysayers who talk about wind and this and that it is a proven fact that in the same wind bouth the 22 and 17 are about the same this round has come a long way from its start Have a great nite all: Coyote Slayer Eat Moose 20,000 wolves can't be wrong

I think that you'd be hard pressed to beat the Mach IV or Javelina as far as case capacity goes. I am hoping that the Javelina will be ideal for the 30 grain bullets - which is why I chose this case. I don't think that the Mach IV will have enough snot to push the 30 grain bullets to appropriate speeds. I had a short barrel Mach IV and the 25 grain bullets would go 3800 fps. I could push the 20 grain bullets to 4,000 fps. With the Javelina, I hope to push the 30's at 3800 fps. I am not familiar with the case that you mention but can say that the proportions of the PPC case are fat when compared to the 6mm size bullets. The .17 with a .222 case is still fat considering the smaller diameter of the bullet. I do understand the inherent accuracy potentials of the PPC as I shoot them in matches, but I think just as important is a quality barrel, good brass prepared properly, appropriate powder, and good bullets.

The only reloading manual I have found with the 7x33 Sako in is the VihtaVouri manual but I thought, if short and fat was the key, and the PPC is "overbore" this case might be just the thing. I also am under the impression that MachIV/221 Fireball cases are not very good quality unless you form them from good 222 or 223 cases (Maybe I am incorrect here). Assuming someone wants really good brass without case forming and a little more powder capacity than the Mach IV, this case (assuming the Sako brass is good) might be the ticket. It is all a moot point for me because I can't find any brass except Bertram and I don't know how good their brass is. The Sako brass is not to be found. Another downside is the .393 brass would require a different bolt face which is not shared by any other rifle I can find. Using a .390 bolt face for 222/223 cases alows you a lot of flexibility if you want to change chamberings.

I think that you'll find if the difference is actually only .003", than this case would work in any bolt designed for a .223 or .222 etc. There is more room for error in the bolt face than .003". If not, it would be a no brainer to open up the bolt face a tiny bit to accomodate the bigger case. And the same bolt face would accomodate the .223 cases as well. My current BR gun can use either .308 based cases or PPC based cases, and they aren't nearly as close in size as the cases you mention.

My 7x33 case heads are .017 larger than the 222. The 7x33 is a lengthened 9mm Luger case. On some finnish sites they list cases for over 1 euro each. Don´t know if they actually have any. Got 400 myself by buying loaded 7x33 (for my 7x33 Sako) before the italians (Beretta) increased the price to this unbelivable level. Have been thinking about a 17x33 myself for some time now. Necking down from 7mm to 17 would require some work, though. AKI
