Two different boxes of 9 mm M882 FMJ were donated to assess any differences in external ballistic characteristics between the two. The brown box was produced by Olin when they ran Lake City and had cartridges with Winchester “WCC” headstamps, while the white box was produced while ATK was running Lake City and had Federal Cartridge “FC” headstamps on the cartridges. Note that Federal AE9FP 147 gr FMJ was used as a control load.
Testing was conducted with a gen 3 G34 with OEM barrel and a gen 3 G19 with OEM barrel. Accuracy was assessed shooting freestyle slowfire at an NRA B8 target at 25 yds. Below are the average velocities and scores for each combination.
Brown WCC/G34: ave vel = 1259 fps; score = 79-0x (large group centered approx. 4” high, 4” left)
Brown WCC/G19: ave vel = 1192 fps; score = 78-0x (large group centered approx. 4” high, 4” left)
White FC/G34: ave vel = 1135 fps; score = 77-0x (large group centered approx. 4” high, 4” left)
White FC/G19; ave vel = 1085 fps; score = 74-0x (large group centered approx. 4” high, 4” left)
Fed AE9FP/G34; ave vel = 946.7 fps; score = 92-1x (small group centered on x-ring w/one called flyer low in 8 ring)
Fed AE9FP/G19; ave vel = 930 fps; score = 95-5x (small group centered on x-ring)
Interestingly there was the over 100 fps ave velocity difference between the M882 in the brown box compared to that in the white box. Recoil was noticeably more stout with the Olin/Winchester brown box cartridges. In addition, both boxes of M882 induced a significant zero shift and were substantially less accurate than generic American Eagle 147 gr FMJ in these two Glock pistols with OEM barrels.
