Ammunition

I had seen this video a while back and I finally found it again. Just another example of home made ballistic testing, that been said it looks like they went thru a variety of brands.

MIchael, have you tried this ammo on your PM9? I have been curious about it for while but it has proven difficult to find around here .
Besides the bullet performance it is also supposed to reduce flash and recoil.

No I have not. I can't find it locally either but usually ATG has them in
stock. Frankly, they don't interested me all that much.
For my longer barrel 9mm's I prefer the tried and true 127gr +P+ ranger
and for my G26 and PM9 my latest infatuation is the HST 147gr.

The Gold Dot Short Barrel 124gr P+ is an interesting round.
It's actually slower than the standard Gold Dot 124gr +P
(1150fps vs 1220fps). While it's classified as a +P round
it barely squeeks above subsonic velocity and in fact is the same
velocity as the non-+P 124gr Gold Dot.

The SB ammo was tested with a 3.5" barrel and the Non-SB a 4" barrel. I suspect the Non-SB would test slower than SB in the 3.5".

Hmmm....interesting....that muddies the water even more

Suffice to say that the Short Barrel version of the Gold Dots
are designed to achieve reliable expansion at the slower velocities
achieved in shorter barrels by tweaking the hollow point cavity and the
jacket of the standard Gold Dot and also by using more efficient burning
powders such that more of it is burned in the chamber and bore to
mitigate velocity due to shortened dwell time.

Whether or not it actually does all this, I have no idea. I
don't think I've ever come across anyone testing this round.

great links! i am sold on the ballistics of the win. pdx/ranger but i was more concerned with the pm9's performance with these rounds. more so comparing the 147gr vs 124+p. from what ive been reading they say with the shorter barrell you should use the heavier round because it allows for better fuel burn. maybe my pm9 will come in soon so i can grab a couple boxes (at $25/box here in p.r.o.mass.)and do my own comparison.lol..

Good to know, I'll give them a try with my guns. I still want to try the short barrel stuff just for the heck of it.
