I have been doing some testing with the DT 40S&W 150gr round and have been pleased. I am averaging about 1,320 FPS out of a 4.5" barreled G23 and the recoil is not bad. I was actually shooting it better than my hot 357 sig. Below is a picture of a couple of fired bullets. The one on the right went through 4 layer of heavy denim and then through 3 gallon jugs of water. This generally means over 12 inches in ballistic gel. The expansion is 0.71". I shot 3 more rounds through the denim and all expanded.

The bullet on the left was fired through bare jugs. It too went through all three jugs and expanded to 0.73" It is hard to see in the picture, but the expansion slopes downward on the edge. The recovered weight was 144.3 gr. You can see a crack, but the bullet did not fragment.

The round was very accurate (precise). More so than my 357 sig.

Thanks for the heads up. Plan on launching any of them through any hard barrier material to see how they hold up?

Not Glass, but I was going to try wall board and maybe sheet steel. This velocity is better than what Cor-bon call 10mm for their 150gr bullet.

Very good 150gr bullet to hold together at that velocity(nosler)?. I pulled a 135gr HST bullet and handloaded it and a 135gr nosler at (1320fps). I fired them into a wet pack along with a factory 135gr HST. It seems the nosler bullet held together a little better.

I guess I should have said they are Nosler bullets. I think Cor-bon uses Sierra bullets.

Thanks for this info! I have been looking at this same round, and wondering how fast it would really be moving out of my G23. I think I will order some.

Have you preformed these tests on any other DoubleTap loads?
