I have 500 brand new pcs of Starline 45 Super brass wanting to be used... anyways I've always wanted to work up the 250gr Gold Dot to run around 1000-1100 out of my G21sf w/KKM barrel. Anybody have any ideas? I'm planning on using Longshot to start with, it seems to do well in both .40 and 10mm (when I used to shoot 10mm). I think the sweet spot for that bullet is within the velocity I'm looking at, it mushrooms huge and moving at that speed, is good medicine for about anything one would ever encounter...within reason of course. I have found that the OAL makes a difference in feeding. The bullet was designed for the .45 Colt, and while the G21sf seems to chamber them all well, I've found my DW 1911 won't chamber any of them...unless perhaps I look at a shorter OAL...perhaps around 1.2"? I will keep you guys posted on my results.
