Anyone threaded a kimber Montana for suppressor? If so, what thread? I’d like to suppress my 7wsm, but a bit nervous about meat around the bore (lack of). I’m ok to cut a few inches off the barrel (24” factory) but the OD still won’t get much more than about 14mm. Not trying to turn this into a bushpig - got a 308 for that, just hoping to protect the hearing of me, my boy and the dog.
Any experience from you guys?

I had my Kimber threaded 14x1 (308) - the factory thread was a stupidly small from memory and 14x1 was an easy remedy.
Ask DPT, they’ll know
I'd recon you'd be able to do 1/2×28 or even M13x1. Ive done M12x1 on some skinny barreled Winchesters, but would not advise to go smaller than that.
From memory there should be enough meat for a 14x1 . But we have also done 13x1, 1/2-28 and 1/2-20.
my 300WSM Montana was threaded 14x1 by DPT however the barrel was also shortened by 4 inches at the same time
Don't go near 1/2" or it could bell out
14x1 would be ideal
my 7 08 kimber is 9\16 x 18 20 in barrel
also got a 270wsm kimber with a ½ in thread full length barrel. No problems.
I had a .308 Kimber but did have problems.Quote:

However, in order to reach .6” diameter, you need to cut the barrel to about 18” (no go).
With Kimber threading the barrel to 7/16x28, the tip of the barrel ended up with a wall thickness of about 1/16”. Pretty thin.
I ended up buying a thread adapter that increases the thread pitch from 7/16” to 5/8”. It's a more universally accepted suppressor thread and the adapter adds strength and rigidity to the barrel tip by relying on the threaded shoulder to support the weight of the suppressor rather than the 1/16” thick barrel tip.
altho 1/2-20 works fine on the three I have, I have been told that its not the best
I've got a 1/2-20 thread on my Kimber 7mm-08, but it's got a 16" barrel. Joel
The biggest 'problem' was that it was a .308...Quote:

Thanks all, I’m not keen on 1/2”, will give DPT a call to discuss when I get a chance. Not sure how you can get a 14mm thread on a barrel with ~14mm OD as thought you needed a shoulder for the supp to pull up against.

don't forget that 14mm is the thread OD, it will have an ID of 14-2x the thread depth, ie something just under 12mm. Hence even if your starting OD id only just over 14mm you will still have a shoulder approx 1-1.5mm deep right around.
Bigger issue is that the thread protector cap will be thicker than you barrel.

Minor diameter of 12.773mm for 14x1mmQuote:

Well I found that hard to believe, That the thread would only be 0.6mm deep.Quote:

Well it was even worse than what MSL stated above. Both would have only about 0.5mm of thread depth.
1 cap was about 12.9mm id, the other about 13mm ID. The barrels were approx 13.9 and 14mm OD over the thread.

Got a photo of the shoulder? Is the 8400wsm barrel a larger profile than the 84lQuote:

It almost looks like gunworks may have put a shoulder on this to maintain the full length barrel when fitting the suppressor

I had one that was shortened and threaded 9/16, then a 9/16 to 5/8x24 thread adapter, with a built in shoulder, was bonded on top. Rifle came like that, was done by Hardy
