I’ve been reloading a long time for many rifles and cartridges. I’ve got a jug of IMR 4166 I’m trying to burn up in 308. Has anyone had luck with any combination they feel like sharing?
 
The only luck I had with it for accuracy was with the lower third of it's load range pushing 175SMK's
I still have over 5lbs of it and I'm trying to find a use for it in heavy 223's or a slow twist 6BR.
 
42.2 of 4166 with a 175 SMK worked well for me. It was 2650.

I think that is what my load is. But it’s in LC brass and is 2650 also. Used a LabRadar

1/12 twist hart barrel on my M40a1 clone.
 
I have only tried it with 155s in my 308. It seems like I liked it my 22-250. I shot some in my 280 with some 139s. I shot some in my 6.5 grendel and 6mm arc also.

Same rifle, bullet, basically same primer, and case. The difference is Varget on the right and 4166 on the left.
 
Mine shoots really well with varget but I think they mostly all do. Lol. Mine shoots rl15 really well too. Kreiger barrel, it shoots everything I have put in it but 155 noslers.
