Correct, that is why I intend to test P45HST2 in 3.5 and 5 inch pistols with my water test tank.

That fits my data...

From 2008...
6" barrel 897 fps
5" barrel 895 fps
4" barrel 865 fps
3" barrel 787 fps
2" barrel 754 fps

From 2015...

I know, replying to myself looks strange, but I wanted to redirect to my last post...

After some research, speaking to others, and crunching numbers... I purchased a quantity of .45 Auto 230 grain...

To me, "heavy for caliber" is better so that there is more bullet material to convert into greater expansion while also helping to keep penetration depth good through increased mass. Once a good...

That specific information is very helpful, thank you ! ! !

I really appreciate the 2 links, especially the 2nd one from 2015 ! ! !

This post contains information that is helpful to me, but I intend to stick with a 230 grain bullet at standard pressures, since the Detonics is designed for that type of load.

My Detonics Combat Master functions flawlessly with standard 230 grain FMJ. So, it should be fine with any 230 grain JHP that has a good bullet shape and is close to 830 fps (or slightly higher) in a...

Agree that function is very important. I want a hollow point load as close as possible to standard .45 ACP 230 grain FMJ @ about 830 fps as far as the same bullet weight, near the same velocity, and...

2 questions for anyone who might know...

1) Assuming Gold Dot Short Barrel #23975GD.230 grain .45 ACP goes 820 fps in a 4-inch barrel, what would the estimated velocity be in a 3.5-inch barrel?

I have a Detonics Combat Master .45 ACP, which has a 3.5-inch barrel and is designed for standard velocity (830ish fps) 230 grain FMJ ammunition. I want to select a hollowpoint that will expand and...

I would reject this load for my usage if that velocity is correct.

That Speer Short Barrel load is listed at 820 fps from a 4-inch barrel on Speer's website. Your data is showing it more than 100 fps higher velocity from a barrel that is 1/4 of an inch shorter, and...

This is the load (Speer 230 grain Short Barrel) I am leaning toward at this point. Detonics Combat Master 3.5-inch 1911's were designed to use 230 grain "Ball" ammunition at standard velocity. This...

I found it.
I found it to be very interesting, too.
That .357 Magnum Federal HST performance in not too different from Winchester's Silvertip HP load. There would be an expected advantage due to...

Oh, sorry... I was forgetting we are talking about .357 Magnum. Now I realize you are loading a 9mm bullet in a .357 Magnum loading. I wonder what expansion and penetration that load would exhibit in...

So I asked because I recently acquired 500 rounds of Federal 9mm HST load# P9HST2. Are you intending to duplicate that load?

Is that HST 9mm load# P9HST2 ?

I looked in my records and found expansion and penetration data for the Winchester .357 Magnum 145 grain STHP load# X357SHP. This data is from Winchester's 2009 LE Duty Handgun Barrier Test Data. The...

I tested the Speer 158 grain Gold Dot HP .357 Magnum load (load# 23960) in 2001 while in the IWBA (Wound Ballistics Review, Spring 2001, Volume 5, Issue 1). The testing was done using water. The...

I like HST ammunition, but will reserve my opinion on this particular load until I see calibrated 10% gelatin testing by someone who isn't using terms like "energy dump".

So... only 1 round fired for each load, no BB calibration of the gelatin blocks before firing, and expanded bullet diameters based on only one measurement taken at the widest point? Not trying to...

Thank you. I have personally water tested the Winchester 180 grain Partition Gold HP, Winchester 145 grain Silvertip HP (both .357 Magnum loads), and the Winchester 158 grain LSWCHP .38 Special +P...

I understand any reputable agency not allowing race guns, that race gun comment was for someone else who had reported reliability issues here on PF that was a competitive shooter.

I have an older...
