I haven't done it.

I prefer a HEAVY crimp on my 444 loads, and heavily crimping thinly plated bullets has a tendency to cut the plating. And for plinking loads, I just use powder coated 200 and 240gr bullets, sized at .432", and Unique.

If you give the Berry bullets a try, please report on your results.

I belong on eroding granite, among the pines.
