10mm What Is It?
Saturday, November 23, 2019, 11:47

After talk about rechambering the GP100s to 10mm Magnum, I got to wondering.

The cylinder is plenty long enough, so I seated some 200 grn Missouri Bullets long. They are coated, so no lube to worry about. These are about 1/4" longer than factory 10mm Auto. These should work just fine in my 10mm Blackhawk too.

Not a hint of pull while shooting either. Can get dangerously close to 401 PowerMag, 10mm Magnum and 41 Magnum power. Not quite, but closes the gap considerably.

I'll order some .050" TK Moon Clips and not look back.
