Has anyone tried 4166 yet?
Supposed to be temp insensitive, copper reducing, and listed next to 4064 on burn charts..

I'm trying to see where it stacks up to varget, 4064,4895,re15....
I have seen data on hogdon site next to 4064.. ( the 4166)

A temp insensitive 4064 sounds real good...

Alliant has some new powder out as well temp insensitive re 23 and re 26
Here is a post on them.

I have two pounds of it for my Mk262 mod1 project. I got it at DSH .

Coooool. Last time I looked I couldn't find it. Thanks! :headbang:

I would be interested in what you come up with....
As I'm using varget to push the 77 smk..

Mapper - I use a load of 23.7 of IMR 8208 for Sierra 77 & 80 grain match kings. 8208 is a high energy powder, work your loads up carefully.
