Here's the testing that Hoot did on the COP 200 grains.

Here's my take on the COP bullets. As you will see, I raised a few questions.

I looked at the COP 200s at Midway for a little bit too long - then they were gone. They still have some 45 long colt (.452) 225gr left, but that's about it right now for this calibre.

I used a modified lee 45/70 crimp. I haven't used washers or anything to move the crimp. My modification job for the crimp die was probably pretty messy. I haven't tried to aim for the recesses in the XPB bullet, I just crimped it where it set.
I used the taper crimp on the Hornady die as well. The taper was down to .475/474 between what my calipers and micrometer said. The side crimp measured around .472/.470 with my calipers. I had to be more careful with the taper crimp on the 200s because with my seating depth the taper wanted to fall into the recess band, and I didn't care to mess with headspace issues.

I loaded up some today - mostly the 275s, but here's one of the 200s

Thanx! I see that your band is the wide version. Mine is the thinner version.


I'll take and compare all these notes and it will definitely come in handy when I finally get started on mine.
Thanx again.
