Hey all, first post here - but have been reading threads on this forum for years. I am currently on deployment and have decided to build out my Kimber Montana chambered in 6.5 creed. It’s a very light base rig as some of you already know. Currently all factory with a Leupold 3-9 on it, 22” threaded 7/16x28.

So far I have ordered a trigger tech primary for it, and a TI bold handle from Chris over on 24hr CF. Currently I am stuck on this portion of the build process- the rebarrel. The factory thread is 7/16x28, as we know. The can I’m going to use on it is my Q jumbo shrimp (yea I know) 6.5 bore and it weights roughly 10 oz and is fairly compact at 5.7”. I want to rebarrel to accomplish 3 goals:

1 - pull as much accuracy out of the platform as possible with a new barrel
2 - eliminate the tolerance stacking caused by the thread adapter - from 7/16 to 5/8. Just cleaner in my opinion to avoid the adapter.
3 - add a little more weight to make the shoot ability of the system easier in different shooting positions.

I know I will be adding in some weight going to a heavier barrel and I’m ok with that. The issue lies in the stock, the way Kimber made the Montana stock, taking too much material from the barrel channel will make the stock more flexible, from forums I have read. So going with too heavy of a contour is not ideal. What I’m thinking, is going with a .750 taperless contour (preferred barrel blanks), adds a little weight and gets me the .750 for the 5/8x24 thread.

While on deployment, I’m trying to gauge how much material I would have to shave off the stock to accommodate the .750 taperless contour. I really do like the feel and handling of the stock, and would rather keep it than go with let’s say, an MPI.

My question is, does anyone know what is, or could possibly help a guy out with measuring the barrel diameter of a factory 84m Montana, AT THE TIP OF THE STOCK.
 
My man! Thank you. Seems pretty feasible to carve out enough material to free float the .750 contour without messing with the carbon fiber shell too much. Unless you have another opinion?
 
My Montana stock had very little fiber in the barrel channel. In some spots it didn’t have any, just the epoxy which was very thin. This was just in front of the chamber area. I don’t think I could have went with a heavier contour without some serious stock work. I’m not sure if they are all put together like this or not.
 
17.5” with the treading. I like how they balance, both have 3-9 swfa and tbac ultra 5. I’ll be adding rokstok lights to both when available. I Use my 7-08 for tracking it has a 16.5” with 3-9 accupoint. it’s awesome.

I too have a 3-9x40mm Accupoint, and want to use an Omega 36M in K-configuration or an A-10. So thinking cut to 18" and be done.

As to the OP...not sure I'd be cutting into a Montana stock...just seems that would be hard to replace if you screw that up.
