I shot plated bullets for the first time this weekend and am pleased with the results. I shot 180 grain Rainer flat nose. By the way I had talked to the rep at Rainer and he told me that too high a velocity and pressure is not the cause of accuracy issues with their plated bullets (I'm not sure if other brands are the same), he said its all about having a light light crimp so the plating does not get disrupted. Anyways, here are my results.....
Ranier 180 flat tip truncated nose, all starline brass, winchester WLP primers, shot from my glock 20 W 6 inch Lone Wolf Barrel.....
Power Pistol, 8 grains- 1240 FPS
8.5 grains- 1315 FPS
Blue Dot, 10.5 grains- 1275 FPS
FWIW- that same load of bluedot, 10.5 grains yields 1300 with jacketed 180 grainers, the plated ones are a touch less- my theory is that I used a super light crimp- about 1/5 a turn on the Lee Factory Crimp die. I usually use a heavy, full turn for the jacketed ones, and I think because blue dot is a slower burning powder that the heavier crimp helps it to ignite better. Because of this issue the faster burning power pistol is the winner.
