Test targets came with both the .22 LR and .22 WMR with targets labeled as being fired at 15 m. Both groups measured 1-1/2”for nine-shots and eight-shots respectively. I decided to fire my groups at the same distance, however I always give myself a Mulligan which is one throw away shot so my groups are actually for eight shots and seven shots respectively.
The .22 LR version was tested with 18 different factory loads. I have found over the decades .22s can be very picky about loads and I always like to have at least 12 different loads to try. The most accurate loads proved to be CCI Mini-Mag HPs at 1,157 fps and a 1-1/8” group; CCI Standard Velocity, 904 fps, 1-3/8”; CCI Quiet .22, 715 fps, 1-1/4”; American Eagle HP. 1082 fps, 1-3/8”; Remington Thunderbolt, 1022 fps, 1-1/4”; Remington Sub- Sonic, 856 fps, 1-1/8”; Winchester Power Point, 1075 fps, 1-3/8”; and the two most accurate loads with both turning in 7/8” groups were the Winchester bulk pack “525” hollowpoint at 1083 fps, and CCI’s Green Tag clocking out at 943 fps. This CCI load required each cartridge to be pushed into the cylinder and I expected such tight fitting to result in accuracy and I was not disappointed.
22WMR:
CCI’s Maxi-Mag +V HP clocking out at 1,556 fps did group at 1-7/8”while the CCI/Speer GDHP designed for self defense gave a good accounting with a 1-3/8” group for seven shots at a muzzle velocity of 1,270 fps. Winchester’s 28 JHP and Armscor’s 40 JHP both shot well at 1-1/2”with muzzle velocities of 1645 fps and 1278 fps respectively.
