BTW, the 255 got a lot of testing to begin with. It was summer and we always need an excuse to go shoot, don't we.
It was nothing to write home about going slow or going fast and in between. It got a couple of tests with weight selected bullets and didn't show a difference. Better deal was the test with weight 'rejected' bullets. No real difference with them either.
If you don't have the mold yet, and don't have the 200 mold already.... think seriously about getting the 200. Especially if they're just for SASS matches.
