Home Forums Hunting & Shooting Hunting Rifles Rebarreling Long Action Kimber Montana 84L to Short Action Cartridge

Montanas are all about light weight and quick handling. If you're going with a short action cartridge, you might as well get it in a lighter, quicker handling short action rifle. Sure the difference isn't much in absolute terms, but in the world of light rifles a quarter pound is a lot.

If I had a Montana in a widely useful cartridge like 270 that shot sub-MOA I wouldn't dream of rebarreling it for any reason. Quit while you're ahead.


As explained above, if you want a 7mm-08, get an 84M. As far as putting a short action cartridge in a long action so you can seat the bullets out long, that may let you get the most out of the cartridge, but it doesn't get you the most out of the rifle. If you're going to have a longer heavier rifle, you might as well get the most out of it. This is a drawing of a 358 win cartridge vs a 35 Whelen, but the principle would be the same for a 7mm-08 and a 280:

If I had a long action & wanted a 7mm, the 280 Remington would be my huckleberry. Added horsepower & you haven't given up any action space to a lower performing cartridge. I love a 7-08 and have used them. But it is NOT a 280 Remington.

Amen.

In a Kimber long action I sure wouldn't rebarrel to a 280 or 280 AI when looking to use the long bullets, due to limited action length, as well as running into that somewhat nebulous recoil wall in a light rifle. It's not always about shoving the biggest motor into a car.

The sheer and utter CLUELESSNESS of Drooling Dumbfhuqks,NEVER disappoints in it's Magnificent Grandeur. Hint.

The 84L is VERY trite in COAL,for a "long" action. Hint.

For that reason,it's a Goat Fhuqk in 280 or 280AI. Hint.

Because bullets matter wayyyyyyyy more than headstamps,a shorter case with a better bullet,never comes in second place. Read that again. Now one more time. Hint.

A 84L 70Win is a steaming pile of fhuqking schit,that can't begin to keep pace with 264 Kreed Factory Fodder. Hint.

The ONLY things you gals "shoot" are your mouths and fhuqking Imaginations. Hint.

Fhuqking LAUGHING!................

Pardon wares that exist,as you Google Gals summons your Imagination and Pretend. Hint.



Fhuqking LAUGHING!................

Yep

You AMAZINGLY Inept clueless Fhuqks,couldn't summons a FIRST Fhuqking Clue,if your "life" depended on it. Fortunately,Imagination and Pretend are free,so even you Brokedicks can "afford" to "contribute". Hint.

1000 words and Google as you MUST,then nod pencil necks in unison,like you "understand". Hint.




Fhuqking LAUGHING!..............

OK Stick...
I think I did alright for an early Montana that shoots accurately. I have $650 invested in it after I sold the scheit scope that came with it. Not bad in a time when Montanas are fetching a premium right now. As I said...was originally looking for a 7mm-08. Sounds like you prefer the 84M and 8400.

In your opinion, how would you setup an 84L to maximize the potential of that action? Other than to sell the 84L and buy an 84M or 8400. Not trying to be confrontational...I really want to know. I realize that you have setup several Montanas to maximize what you can do with that platform.

The (3) things that matter most,are bullets,bullets and bullets. Hint.

The 84M is as maligned as the 84L,in that they are both very trite in COAL "latitude". The 8400 Whizzum's are THE cream of the crop,due COAL latitude,with the 7 Whizzum being The Belle of The Ball. They'll 180 out of the gate. Hint.



NO chambering,can be better than it's bullet. I would MUCH rather gun a 7-08 with .796 BC 180's,than a 280 squirting parachutes. My 280's are typically set up to kiss that 180 at 3.585" COAL. Same goes 7mm RemMags. Why? The cases are of like length and share the same box/follower in a 700 L/A,leaving room to chase lands. Hint.

With a 84L Donor on the table,I'd go 8" RPM 7 Mouser and throat 180 Smooches,from it's tiny in comparison box. Hint.

In a 84M,I'd go 284 Bleedmire,throated for same. Hint.



Bullets,bullets and bullets. Hint................

I've got 2 260's built on long action 700's . for the reason of seating long bullets. in ideal position to lands and still running through the magazine.
these 2 I shoot for the high power silhouettes get in the hunter class you have to run the ammo through the magazine... I built these long before the creedmoor was ever thought about...

Leave it as it is.

For me I've found the enjoyable upper recoil threshold with the 84M and 84L Montana's is the 308 Win in the M and 270 Win in the L. Add bore size and powder and things become too sporty (I've had something like 16+ Montana's).

If you don't like the 270, trade it for an 84M Montana.

700's are easy. Hint.

Simply go AICS binderless DBM and you are there. My 8" Hart 260AI loves 147 Smooches,fed from same. Hint.





Just sayin'. Hint..............

Brad...I think I will leave it as is. The juice just doesn't seem to be worth the squeeze, given my barrel is showing accuracy with me behind it. I was curious to see what I could do with a LA Kimber Montana.

Big Stick...thank you for answering my question and providing a "method to the madness" in trying to address optimizing an 84L. I'm picking up what you are putting down regarding choosing a high-BC projectile. I will be watching for an 8400 to turn up at a good price.

ALL...
I appreciate your input on the subject of rebarreling/chambering an 84L. Thank you for answering my questions. I will refer back to this thread as a template, should I ever get the itch to do something wild with my Kimber.
