Outstanding, Doc. Thank you. :)
Thanks as always,Doc. You're continued testing reports are always appreciated.I wish you safe travelling on your upcoming speaking engagements.
Yeah the new Critical Duty is nothing that im impressed with, thats for sure the expansion was nothing like hornady claims in bare gel or through heavy clothing not to mention I shot one into a few jugs of water (oceanspray cran berry juice) bottles and the .45acp failed to expand. and hear these are suppose to be great for going through barriers... I think not LOL
Thank you for the information.
Thank you for the information. How dose the 9mm 124 +P compare?
Not sure what 124 gr you are referring to, but here are a few tests: https://www.m4carbine.net/showthread.php?t=88091
The HST. Thank you for the link.Quote:

Thanks for all the great info!

Hey Doc, do you have any videos of the testing you do ?? and or website ?? I enjoy reading all your test info and data..
T2C--the 147 gr is subjectively a bit softer shooting.
lyodbraun--Uh....no.
I've been waiting on the 135 gr. bonded test. Ty for posting.I did think there would be a difference in the results though.
wow look at that 9mm 147 hst2 and hst4...no reason to bother with the +p with that bullet.
Thank you Doc! :DQuote:

It depends. Typical test guns in 9mm are around 4" in barrel length. If you are using a barrel under 3", or a long slide gun the +p is beneficial. I have noticed that some longer slide guns cycle better with +p. With standard rifling from a Sig P228 4" barrel I average around 965fps for standard 147gr HST, and 995fps for the +p version. So I prefer the +p version.Quote:

I was also wondering about that. Thanks for posting it.
Doc, the Critical Duty 9mm 135 +p lists velocity at 1185. Is that accurate? It seems a bit higher than I would expect, especially compared with the standard load's velocity of 1085. Did the +P "feel" that much more stout?
Doc,
Thanks for this and all you do for the shooting community.
It was the average noted for the 15 rounds we fired through a G19 during the testing...
I carry the +P in my Glock 19 Gen4 to assure reliable cycling. I am always a little bugged that Ballistic Gel tests are done at very close to muzzle velocity.Quote:

Also, when testing rifle rounds, why don't they move the gel out to 100, 200, 300 yds, etc to get a better idea of performance in the field. I know much of the metric is to compare one load to the other, but it would be interesting to see how the rounds perform at the lower end of their minimum expansion velocities.
Doc, does Federal state what the minimum velocity is for reliable expansion of the 9mm HST Bullet design??
There is no difference between P9HST2 and P9HST4 at 25 yds.
Rifle testing is typically done at 3-10 yds, 100 yds and 300 yds; just because it is not easily located on the internet does not mean such testing has not been done. Out beyond 300 yds, almost every projectile simply enters tissue, yaws 180 degrees, then exits.
So Doc, with all the testing you have done what's the go to round in .45 acp... ??? ,..

Likely one of the ones listed here: https://www.m4carbine.net/showthread.php?t=19887.
I personally used .45 Auto 230 gr HST (P45HST2) when I carried a M&P45 in 2011 and when carrying a 1911 prior to that.
