IMR 4166 powder?

[cornhusker]

Has anyone tried this powder in the 223? If so how did you find it to be?

I haven"t but use 4895 in my 223. It will be interesting to see what you learn.

cornhusker,

I'm using 25.4gr. of 4166 behind the Sierra 53gr. HP match bullet. I haven't chronoed it yet but it yields .5 at 100yds for me. I've shot it with a 40 degree temperature swing at 200yds and all groups landed exactly where they should have. Hope this helps.

How well does it meter? I use 8208xbr and it meters pretty good in a Dillon

4166 does not meter as well as IMR 8208 XBR. It meters about like Varget.

I worked up a load with some 4166 pushing some 178 Amax out of my .308. The node I found with comparable velocity to my tried and true 4064 load was rather narrow and unforgiving.

I will be testing it in my 223 wylde bolt action ..

Just bought some from Cabela's last week to try with my .223 and 6.5 Creedmoor and my buddies 6.5 Grendel.

Finally got to the range this morning while the wind was fairly calm...The 4166 seemed to be a good powder in my 223 with the 69 gr sierra match bullets.
Only shot at 100 yards and had 1 inch or less 5 shot groups..Smalled was 3/4 inch. But I am looking for a bug hole so it will do better at 300. I am sure with some twinking
It should work well...I want to try the same powder with some 77 and 80 grain bullets to see how well they might perform at 500 yards...
