I ran a few rounds through the G20 the other day at the local indoor range. I used AE 180gr FMJ and some Buffalo Bore 180gr JHP. I still struggle with rapid fire a bit due to the girthy grip, I have re-grip every 5 rounds or so. It will be going to Cold Bore one of these days for a reduction. 30 and 45ft are 10 shot groups with the AE milquetoast ammo. At the max range distance of 65ft, I ran both ammo types for a five shot group. Did OK with the AE, dipped the muzzle on my 4th shot with the BB stuff and pooched an otherwise good thing. Yes, the BB felt noticeably hotter. Chrono data for this load seems to support the factory specs. I'll keep the remaining 15 for special occasions.
