Not sure what exactly you are looking to accomplish.

Punch the 7mm08 Ackley....... That'd be my recommendation as well if a guy wanted more than the 7-08 in the 84M. OTOH, I can't fathom the point of more than 7-08 in that little rifle. There really not need be a point about it, other than you will get some additional speed, if not quite a bit ... as well as brass that never has to be trimmed ... I just had my LVSF 7mm-08 torn apart and had a Rock Creek bbl put on, chambered in 7mm-08AI ... it feeds perfectly, and I'm getting a hair over 3300 fps with the 120 TSX and Vmax ... VERY HARD to not like that ... to boot, the recoil feels the same as I recall it when it was a SAAMI 7mm-08rem ... but yah, I can't argue your point about it not being necessary ... close to 3100 fps with the SAAMI chambering, or up to about 3300 with the Ackley ... either way, you're good to go ...

Not sure what exactly you are looking to accomplish. I mentioned the 284 case with the 25-284 in mind. I want to seat these 80gr TTSXs out and run them fast.

Throw it in a SUCKS and be done with it, or turn your Kimber into a 250AI (assuming the aforementioned 284 case issue is an issue)

.473" s/a Montuckys have a magbox shorter than a s/a Remmie.
I'd have zero qualm going 284Win on the Montucky,save the backwards step in COAL latitude.

I've also wondered why the 284 case would be safe in the (N)ULA but not the Montana. I have both in the house and have measured them in the past. They're extremely close in diameter.
Mag length in mine wouldn't be any more of an issue than in a SA 700. My 700 ADL and 84Ms have equal length mag boxes (2.81"), though the 700's is easier to extend.

I've never seen an 84M even reach 2.800".

If you really wanted to go different, you could try 25 Souper AI, that might get you close to 25-284.

Now since its a Kimber thread, I feel obligated to ask why they didn't stretch the 84 to make their LA rifles??? Then Brad could've said that if the 7-08 wasn't enough gun, you could buy an 84MLA in 280, but sadly Kimber missed the friggin boat on that one. no kidding...I've always wondered why Sako didn't stretch the L579/AII to handle an '06 case.......a no brainer IMHO.....instead they put the '06 cases in the bigger L61R/AIII/IV/V action.....strange...sure they save manufacturing costs but with the lightweight rifle being all the rage these days it would make sense now...guess it wasn't big deal in the 60's....

I've never seen an 84M even reach 2.800". I'm loading 100gr BTs and 80gr TTSXs bullets in my 257 Roberts Montana to 2.80" with a smidge left in the magbox.

Steelhead's 250AI recommendation is interesting for sure. 257 Roberts velocities (possibly more) with the ability to seat bullets out and still have lots of wiggle room in the magbox. Fireforming doesn't excite me, but might be worth it in this case (no pun).

I can get 100 NBT's at 2.810" to fit in my 84M Bob magbox. Of course, distance to lands is another .1" or so...

I shoot a Montana in 7/08 and a 6/284 in a (long) action 700. The 6/284 is in a long action because the parent case barely fits into a shorter action, preventing long bullet seating with even a .243 bullet. Given my experience with loading the Kimber, I'm wondering if there is enough room in the box to handle the 284 and allow for anything less than maximum seating.

Ain't no trick to 'fireforming', work up loads whilst doing it.
Here's a hint, bullet/powder combo that does well in a fireforming load, will typically do the same with a few grains more powder added.
I run my fireforming loads to the gills anyways, they shoot well, and I have killed game with them. The beauty of the Ackley, you don't have to shoot formed cases in it for to work just fine.

I just wish they would make the Kimbers in a lefty version....(sigh) You too?!! Oh yea. I wouldn't have gone the Rifles Inc. route but then it's in 284. Sounds like the Kimber and the 284 are a "should-not-go", not a "can't-be-done."
