Snap!
I was going to post the same pics but was on phone :)

I vote .284 Win case shortened to say 47/48mm no improved shoulder necessary.

The short saum has been used for quite a while now in the F class world is it really something new?

My idea is a case the right length for a SA, with more poke than a 7-08 but not quite a 'magnum'
A case 'designed' to suit the package around it

this is what i want to do . i had a talk with mr duley before this thread started and this was what we came up with.im just waiting on a price to do this to my sako.

would you need to shorten the SAUM? extend the mag box a bit .... shorten the neck a tad blow it out parrallel with a sharper shoulder and get very close to WSM capacity in a shorter case..

or the short 284... but its allready pretty parallel and has a pretty sharp shoulder so not too much modded...not cool enough :P

Or utilize the small primer 308 brass, blow it out shorten the neck.... look a bit different to std then

or just neck it down to 7-08 and it will do the job :wtfsmilie:

still like the 338 better :D

The more I read this the more I see an ugly twin of the 7mm08 getting born:TT TT:.Still a bit of fun though:thumbsup:

I must admin I like the idea of a 338/375 or 416 SAUM, I can't see that freight train of a projectile stopping for much :thumbsup:

338 SAUM = ~338RCM?

.532 RCM (just above the rim) vs .550 SAUM (300)
.516 RCM VS .5357 at the shoulder
1.568 to shoulder RCM vs 1.5383
same OAL

Use the SAUM but push the shoulder forward and 40 deg and it would be quite a step up from the RCM in capacity :)

Be interested to hear how you get on with this... almost sounds like my ideal setup. Not sure if I have the need for bigger magnum.

Yeah me too.

I suppose we'll know once the NZHS Wildcat is done. It seems that majority are going with this theme.

.284 shortened with the improved shoulder... 40degrees?

So do we have a consensus on this yet? It seems .284 Win case shortened and either improved or not. I vote not improved, might have feeding issues then.
