Here's the test range, 10 yards, my lead miser lead catcher backstop <( http://castboolits.gunloads.com/showthread.php?342719-Building-a-gt-gt-gt-LEAD-MISER-BACKSTOP-lt-lt-lt-for-Practice-Load-Workups ) and this old rest. I had the Chronograph set up between me and the target to get all the details while shooting for groups.

Originally I just wanted to find a good load using the Power Pistol Powder and the 213 grain PC'd Clear Gloss SWC's. These are made from 50/50 Isotope & COWW's + 1% Sn @ 11.8 BHN, sized .4515" & came from a Lee mould.
BUT...
I remembered having a box of 500 of these 200 grain COWW lubed SWC's @ 12 BHN, sized .451" & came from a Lyman mould I think... and thought why not compare the two side by side in the same load workup...just for kicks and to have something to do.

Here are the stats...it looks like in both cases that 6.7 grains got the best SD in both PC'd & Lubed although I think the PC'd rounds gave a tighter group overall in these 3" bulls eyes.
