I’ve used a lot of Xtreme bullets - great company and consistent bullets. I haven’t specifically used the 147 gr, but I’ve used the 115 and 124 - all performed well.
I’ve gone through 20k of them. Accuracy isn’t great with Titegroup (3.4gr) out of either my Gen 3 Glock 19s (890 FPS) or my MP5 (1000 FPS), but it does better out of my Gen 5 Glock 19 for some reason, holding A zone at 40yd. With my MP5 and Titegroup, I was getting 6” groups at 50yd and that held to 12” at 100yd. They do better with Longshot (4.8gr).
They keyholed out of my USP with Titegroup, but I haven’t tried it with Longshot loads yet.
