Greetings, Just came back from the range, playing around with some 230g Hornady XTP bullets over Power Pistol. Today is a sunny and 65 degrees with almost no wind. Just for comparison – some factory ammo; Hornady .45 AUTO “Custom” Factory Ammunition 230g XTP HP +P Velocity –Box Listed @ 950 fps/my 6 shot average = 887.6 fps Standard Deviation = 6.58027 OAL – 1.230” Primer - Federal Large Pistol Primer #150 Bullet - 230g XTP (Hornady) Bullet length/DIA - .637”-.638”/.451” Powder – Alliant Power Pistol Powder range – 5.5g up to 7.1g (Hornady Reloading Manual 9th edition) Powder burn rate - #33 (Hodgdon) Test charges - 6.9g – 7.1g – 7.3g Bullet seating OAL - 1.230"(Hornady factory ammo length) Test gun - .45 ACP Glock G21 w/4.60” barrel Velocity numbers; (6 shot average) 6.9g = 844.83 fps Standard Deviation = 10.57967 7.1g = 870.3 fps Standard Deviation = 9.93311 7.3g = 897.83 fps Standard Deviation = 6.04704 Accuracy tested at both 7 & 15 yards from both a seated/gun rest & standing free hand position. All rounds fired without any problems, the velocity numbers tell the story about the feel of each round. The accuracy of all three was very good especially the 7.3g test charge (at 7 yards) but this was a round that I would not want to shoot very many of at the practice range… very firm kick! Taking all things into consideration I have to give the nod to the 6.9g test charge as the best all around load. This was a close call in many respects but in feel with respect to feel, reacquisition of target and accuracy, the test charge of 6.9g was the best. Power Pistol sure lived up to its name during this test. A very strong performing powder in these tests (but not over-powering), it burned very clean in all test charges with very little sigh of over/under burn in and outside of the spent brass casing. Just wanted to post my results from a day at the range. Be safe out there Wanna kill these ads? We can help!
