Took my Flattops to the range and tested several loads. First my .44 special 5.5" seems to like 200grn XTPs over 8.3 grns of Unique best and got a bit over an inch at 25yds 5 shots. Next my 6.5" .44 mag. likes the 270grn Gold Dot soft points over 17.5grns of 2400 giving a 1.130" 5 shot group at 25yds. I was shooting off a bench with a shooting bag as a rest. Hoping to see how the magnum performs on deer and maybe a hog hunt this year.The magnum is broke in and the special only has less than 100 rounds so far. The only mods on both guns is grips and trigger spring replacements. The odd part is 17grns of 2400 in the magnum shot about a 5" group but 17.5grns gave much better results.
