No, it won't be videotaped, and I will not be chronographing, either.

Am aware of limitations of water testing, that was my method of testing while in the IWBA for all of my testing that was...

I am planning to buy some .357 Magnum HST and test it in my water test tank, along with a new test with recently purchased .357 Magnum Silvertip.

Comparison...

My .357 Magnum is a 4" barrel Ruger GP-100 at/near 42 ounces, IIRC. The Silvertip recoil is not an issue at all, so not concerned about the HST.

Agree about Winchester to a degree...

I just bought 300 rounds of 230 grain HST .45 (P45HST2) for my Detonics, I think it will work fine, and expand OK, too. Plan to test soon.

First question is yes, and I have to admit I had no idea the P9HST2 load had been changed until yesterday. I also am glad it was changed, I prefer 13 to 14" penetration over 12".

Please let me...

OK, back to the topic of .357 Magnum...

Although the .357 Magnum HST and Silvertip data above is similar, the HST is a bit better. Add to that the obviously better bullet design and function, and...

I was looking at old testing data...
I got the 9mm HST ammunition out that was used in my testing and the unfired sample has no visible primer sealant. Also, the fired/expanded bullet is fully...

I recently acquired a Detonics Combat Master SS .45 ACP with the wraparound Pachmeyer? rubber grip. All original, only had to replace the magazine spring with a Wolff. Totally reliable, and very...

My ammo has the blue primer seal, I think I may have been looking at older data than I thought I was looking at ???

Purchased less than a year ago...

Do you know when that change was made? My data is from this year...

Comparing your data to my data...

Federal .357 Magnum 154 grain HST (your data) vs Winchester .357 Magnum 145 grain Silvertip (my data)

Federal HST (your data)
Bare Gelatin 15.5" Pen / .65"...

Suggest reading DocGKR's "sticky"" titled: "Basic Wound Ballistic Terminal Performance Facts"...

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...
