Across the Finish Line

Yesterday morning's range trip to Marion County Fish & Game finished up the 2,000-round test for the Glock 20 10mm pistol.

I finished up the last fifty rounds of American Quality Ammunition 180gr FMJ and also fired twenty rounds from a company I hadn't tried before, Bobcat Armament out of Shelbyville, Indiana. Bobcat Armament is apparently the FFL portion of Bobcat Steel, a well known local supplier of steel targets.

I chronographed one ten round string from each brand. The American Quality Ammo FMJ turned in pretty typical 10mm range ammo numbers: 180gr bullets at just barely supersonic velocities.
LO: 1082
HI: 1121
AV: 1110
ES: 38.93
SD: 12.28
Reasonably consistent, too. The Bobcat Armament stuff, on the other hand, was some honest 10mm, with noticeably more thump on firing and commensurately larger numbers on the chronograph.
LO: 1192
HI: 1242
AV: 1225
ES: 50.56
SD: 17.11
That's six hundred foot pounds of energy, which is nothing to sneeze at, if energy numbers are your thing. It certainly equals or exceeds most popular commercial .357 Magnum deer loads.

In firing my last ten rounds of the Bobcat Armament stuff, the now filthy Glock had one last light, off-center strike on round number sixty-one of the day (#1,991 of the test).

This makes 2,000 rounds since the Glock 20 was cleaned or lubricated, with eight failures to feed (#401, #454, #1,213, #1,297, #1,413, #1,593, #1,777, #1,907) and twelve failures to fire (#598, #1,016, #1,029, #1,376, #1,595, #1,628, #1,633, #1,640, #1,683, #1,685, #1,727, #1,991). Here endeth the test. Close-up photos of the dirty, disassembled gun to follow, along with my general thoughts, in a wrapup post.
