IMR 4166

I see both 8 pound and 1 pound available, I may pick up some of this.

I made the switch to extruded powders, and all the ball powder I have has been sitting ever since. I will probably use the tac, and cfe223 then get rid of the other rremaining ball powders I have. I might keep them for another powder drought, because I will take ball powder over no powder.

I may also test the cfe223 to see if it will remove existing copper. I was looking at my marlin 336, from a distance I thought I had rust. A close inspection revealed a lot of copper. So I may look if I can find some data using the cfe223, and see if it will remove the copper.

I would be really interested in seeing that. Have you found the CFE223 to be very sensitive to temperature changes? I'm guessing it's similar to TAC in burn rate and temperature sensitivity.

I picked up a pound of CFE223 to try yesterday. The velocities it can push in the new Hornady manual are phenomenal. 75gr bullets @ 2900 FPS (20" barrel). Should prove interesting to see how it loads and shoots.

I have not done a whole lot with it. I stumbled on to imr8208 at around the same time, so I kind of put off all the projects I had planned for the cfe223.

Yeah, XBR is currently my favorite powder. It's some amazing stuff. New components seem to keep me intrigued though.

XBR is currently my favorite powder.

Me too. H322 gets me better accuracy, but XBR gets me great accuracy and hotter loads.

The only ball powder I get is when I buy XM193 to pull apart. I have a bastard AR that I run ball powder blaster ammo in.

Why do this? Do you use the cases with crimped primers for other purposes?

If anyone comes up with a good 4166 load for the M1 Garand, I would love to have it.

I pulled some down and loaded my own Mk262 clone with XBR. Mainly for the crimped primers.

Exactly. For defensive ammo, I run a pretty hot (near 5.56 mm pressure) load. I want virgin brass and crimped primers. I almost never have a case separate or pop any primers.... but Murphy's law and so forth.
