I tried the paper plate thing with my M&P Pro 9mm. But my shooting was at 10yds, 25yds and 50yds. My results were that I needed a bigger paper plate. At 10yds 3-4" groups, at 25yds 8-10" groups, at 50yds I had to use a D-1 Action Pistol target just to get the group to print on paper, the groups were about 18-24". I shot 115gr Lead, Jacketed, round nose and hollow point, I shot 124gr lead, Jacketed, round nose and hollow point, I shot 135 grain jacketed round nose and hollow point, I shot 145 gr lead semi wadcutters, I shot 147gr jacketed round nose and hollow point. My Springfield 5.25 in 9mm shoots groups that measure just under 3" at 50 yds.....go figure.
