Thread: Kimber Montana Ascent 280AI Load Development

What length are you going to chop to?

22" and hopefully enough meat there for 5/8x24 barrel adapter.

Well...barrel bedded, barrel chopped to 22" and A-Tec QD suppressor on it now. Tried ladder with 180gn ELDMs and RE26 starting at 58gn and going up in 0.2 increments.

Split the ladder test into 3 shot groups. First group nice triangle shape 0.8MOA. Keep in mind last time I shot 180gn I stopped after the first 2 shots that were 2" apart.

Definitely showing some promise.

Looks promising n good speeds too

Yes not much of a drop. I did forget to run the brass through a body die.

Sitting at range with first 3 shots of 162gn eldm ladder test. 60 and 60.2gn same hole on left then 60.4gn to right. Parking ladder test (up to 61.4gn) to repeat a group at 60.2gn.

Hi Tikka7mm08,
What's the app you're using to measure your groupings?

How does the labradar go?

Cheers

App is Range Buddy. Labradar goes great top kit.

Just go and shoot a deer

Soon. Want to get the stock cerakoted first.

@Tikka7mm08 have you decided which load you're gunna run with....both look good.
Oh...and go shoot something before you need a new barrel

Not sure yet. Yes....will do. Gotta pick up the Montana 308 and test that next.

Mate, you’ve got more patience than me. I’d have deep sixed the bloody thing by now!��
