New powder in my 6mmAR - 454bore - 04-23-2018
Tried some alliant 2000-MR with Hornady 108ELD's.
31.5 grains got low ES and SD.
The velocity averaged 2731fps.ES=9fps and SD 4fps.
Half inch groups with some 3 shot bughole groups.
Burns cleaner than CFE and easier on brass than H-4895.
I read that it works very well in the 6mm Turbo 40.

How long is your barrel? That looks to be right at the burn speed of RL15 which Whitley likes.

It's a 22 inch Krieger.
2000-MR is a little slower than RL15.
It meters much better than the stick powders.
It's a ball powder similar to CFE and made at the same plant.(St Marks)
Some say it's the same but it's not.
It seems to go unnoticed.
I picked it up cheap because it sat on the shelf for a while.
Will be getting more.
Whitley's article on the 6 dasher is where I read about it.
The 6mmAR has 36 grains water capacity,the turbo 40 has 37.5,and the 6 dasher has 40 if I remember right.
