I've got a LW 5.2" threaded barrel for my g20sf. I've been kicking around the idea of picking up a suppressor for it. The next step would be for me to work up a good load to optimize performance of the can. I'm thinking a 200gr bullet around 1050fps (sub sonic). I've got a lot of 200 BT HC on hand or would a 200gr nosler or xtp be better. I'm thinking purely in a defensive situation. I've got some A#9 and Longshot on hand , but I think the Longshot is out because it seems to have a lot more bark in my hot loads than A#9. Maybe somebody could recommend a better powder. Any comments would be nice.
