I have tried 200gr loads before, out of a Para P16, and an STI, and I thought that they cycled kinda like a 45acp, I also tried the 155gr, and I shot those for awhile, they made the gun feel real snappy, and the slide moved real quick. I found that I liked shooting ammo loaded with 180gr bullets the best, it wasn't as fast as the 155s, but faster then the 200s. I sometimes felt like I had to wait for the slide to cycle with the 200s, and the sights seemed to track better with the 180s.
That was shooting USPSA Limited at a major power factor. When I switched to Production, and started shooting minor I tried just using the same powder charge as I did with the 180gr bullets and just switching to 165s. That worked ok then I tried cutting back the charge and using up the rest of the 180gr bullets I had left. When the 180s were gone I went back to the 165s, and loaded them lighter and lighter until I got a load down aroud a 140 power factor, and that load in an XD40 Tactical with an 18# spring has turned out to be one of the flatest shooting loads I have ever used. I don't have to worry about not making minor :shock: , and the sights come right back to the middle of the A zone, if I do my part.
If you want to try a good JHP without going broke try the ZERO bullets, and you can find them at
www.ghostholster.com they run $165 for 2000 of the 165s and that includes shipping.
Well that's what this IPSC shooter uses if that's any help
