I have a G20 I hunt with. I have had good luck with 180 grain loads a little over 1200 fps. Double tap advertises another 100 fps and I have loading data that will match that but the accuracy was headed downhill before I got that high. Thinking of trying double taps 200 grain load for hogs. I haven't had a problem with 180's on hogs but I have only been comfortable taking ear shots on anything with thick shoulders.
