Near perfect weather and frame of mind set out to testfire. First group held foreend and boresighter was almost bullseye so fire 2 more and the group opened out.

Went up 0.5gn to 46.5gn CFE and changed hold to hold on top of scope. Next group brilliant. Primers flattening but not hard bolt lift so didn't shoot heavier powder loading.

SD respectable as is speed. TBH was dreading recoil as have not enjoyed 308 in past in much heavier rifles inc SLR. Found this more a push than kick and very comfortable. Trigger is outstanding as is working the action.

Very pleased all research came together well. Now to repeat

its plurry amazing what a suppressor will do for your confidence level in any calibre,the .308 is a pleasant doddle to shoot when you remove most of the noise factor...borrow one from someone with same thread and hole in the end and try it.....bet you will buy one VERY soon afterwards.

I doubt someone will have a suppressor for this oddball thread! Plan is to suppress. Barrel is 22" and so might take back 2" and add suppressor. I've had 1 or 2 in the past and the odd brake. I like both.

Trying to measure with range buddy...zoomed in this time to pick hole centers.

You can buy an adapter to go from kimber thread to something more available. You "local" should be able to get one for you from the importers, or you could get the barrel chopped.............mine is away being chopped now to 20 (not a 308 though)

Yeah the adapter is pretty unattractive. Comfortably a 600-750y rifle at present.

with those results id just use it

The guy I have seen with one has loctited in to the suppressor not on the barrel as he only uses it on the one rifle.

I really like the Montana much much better gun than the one it is "standing in" for in every respect especially as it cost considerably less and is far more reliable.

That is a good idea to have it in the suppressor. Talked to the DPT guys and they said you need to put the back of the suppressor on first as it won't clear the adapter...then the adapter and rest of the suppressor... I think 2" off and a suppressor is the way forward...but not rush now.

do you want to swap for a suppressed adirondak

I was looking at them and the mountain ascent but the stocks of them put me off due to their lack of durability.

Yep, nothing gained going to an Adirondack from a Montana. The stock coating on the mountain ascent and Adirondack is crap.

18" barrel and A-Tec suppressor. Groups not as good as last time. Might go up/down 0.5gn and see if they tighten back up. Velocity not too bad after a 4" chop.
