New lightweight mountain rifle, with a heavy side of Grizz. Debate starter.

X2. I would want all the case capacity I could for throwing heavy large caliber bullets from a short/mid length action.

I love the X57 case, but with a .375 bore it is hard argue against the .284 case... the real world differences are minimal however... it would be an unusual circumstance where the end result would differ much, if at all, between the 9.5X57 and .375/284.
 
Hoyt......close range energy on target would be quite a bit more with the 284 case........would it change the outcome of an encounter.......maybe/maybe not, but those extra ft/lbs sure wouldn't hurt. It would also be flatter with a 235 or 250 gn bullet for a few longer shots as necessary. I am just conjecturing but experience would tell me that there should be about 100 fps difference with any given bullet weight and the shorter 284 case would allow heavier bullets to be seated out farther in that action. All definite advantages when talking arms length grizzly encounters.......personally I want to hit them with the biggest hammer I can get my hands on, and in the stated action with a .473 bolt face that would be about the biggest hammer one could build. It would also be no slouch out to about 300+ mtrs with 235 or 250 TSXs or 260 ABs or Parts. One could load 300 gn Matrix RNs for the wandering around in the bushes part, and carry some lighter bullet loads for the long shots on caribou, sheep or goats, just need to sight the rifle in for the lighter bullet loads cause if you NEED to use the 300 RN it'll be at "powder burns on the hide" distance.
But hey that's just my opinion, Angus can build whatever he wants on his multi thousand dollar titanium action.....................

Actually the case capacities are indentical for .284 and improved x57 (9.5 is an improved case), with a .375 neck both the .284 and x57 hold 69grs H2O. You could seat out further with the .284, but may lose one in the mag, so it's a choose your flavour type deal.

Hmmmm... that makes the choice simple... I wouldn't have thought the cases had equal capacity.
 
You're not going to put camo on that stock are you?
On a titanium action that seems wrong
I'm thinking dark green spider webbing on a darkish tan
 
Just a nother thought to throw into the mix.......

X57 case is 2.23" long
284 case is 2.170" long
Wsm case is 2.10" long

WSM case holds 79-83 gr H20 (depending on case manf.)

Have you considered a 375 WSM?

I have been following this thread with some interest, this was the only "intellectual" comment I could think of!

Cheers!

Can you use the WSM case as a basis? Would give you more oomph on bear and range on sheep if you're planning on using heavy large caliber bullets. Its a neat concept but its going to be full of compromise as a grizzly stopper and a lightweight sheep rifle are at the extreme opposite ends of the rifle spectrum.

I've looked at it, Stuart is willing to cut titanium any way you want to pay him too. 375-325 WSM cases would form easily. I do struggle with how the WSMs feel in feeding, and the magazine capacity penalty. With a bolt action I like to walk with the chamber empty, and having a minimum of five down makes me happy.

I suggested it but got shot down. :redface:
 
Ever thought about making your own wildcat? My grandad was a wildcat guy, the middle round is a shortened 375 h&h, a hair bigger then the 9.5x57 (left). It proved itself on African Cape buffalo more then once. Just a thought.

 
Interesting to watch this unfold , well at least when it is on track :)
My question about the 9.5 x57 is can bullets be seated long enough to get a sufficient powder charge and fit the intermediate action ?
Some velocities stated look pretty stout
Cartridges like the 350 mag are more impressive when seated out longer than the ole 600 action allowed
 
With respect to wildcats, I'm working with an interesting one made by my late Brother at the time of his passing.
The dreadful cancer he had caught up with him before he could actually finish the rifle.
Its a '98 Mauser done up in his own variation of the 375/06 AI.
Shortened slightly more than the Ackley version and blown out a tad more, it seems to be not too far behind my H&H when using a 270 gr. bullet.
I have a lot of work to do with it not to mention getting it blued, but so far it looks promising and in a light package, at or slightly under 8 lbs. scoped depending on the weight of the glass used.
 
Kevan,

A good friend of mine has a 375-06 AI barreled up by Bevan King, and gets over 2600 fps with 270 spitzers in a 24" barrel. Have no idea what pressure is, but case life is excellent. I wonder is he used Bevan's reamer. I know they were well-acquainted as I met Charlie through Bevan.

While we are on the subject... Ted, Angus et al.... who would you recommend for a rechamber/rebore??? My guy is ill and won't be able to take on new work for a long while. I have two projects in .284" (7X57) & .358" (.358 Win).
