BufordTJustice - have you ever done any back to back recoil testing of the 147 grain +P HST and the 147 grain +P+ Underwood Gold Dots? I'm curious how they compare in terms of shootability.
Ron3 - For sure you should always verify functionality with your weapon before carrying the ammo. I prefer 9mm to larger calibers for the added magazine capacity. It seemed like according to Doc, for quality JHP ammo 9mm = .357 SIG = 40 S&W = .45 ACP in terms of performance. Given even remotely similar performance per round, I'll take the extra rounds please.
Correct me if I'm wrong, but at 1150-1175fps, won't the Underwood 147 grain +P+ be supersonic? I think even the Underwood 147 grain +P at ~1125fps would be supersonic or at least transonic. I wonder how much supersonic vs subsonic actually affects shootability... BufordTJustice, can you chime in?
One more thing no one has brought up yet is the different casings. Federal/Speer casings are nickle plated, while the Underwood casings are bare brass. Would this have any real world effect on reliability or corrosion resistance?
Badger, I have shot them back to back and the Underwood is hotter, but even with that ammo my g26 is still very easy to shoot very quickly. I do use a Wolff two piece guide rod and 22lb spring set....runs WWB and Tula with no issue and soaks up a good bit of recoil and net muzzle rise. Std pressure 9mm feels like .380.
Federal's +P isn't that much hotter than their std pressure 147 gr HST to my mk1mod0 hands. The Underwood feels very similar to Winny Ranger +P+ i used to have a couple years back.
The 124gr round is a littler over driven with the Underwood loadings. The petals begin to curl back on themselves a bit. The 147 gold dot doesn't do that. I don't think the subsonic/transsonic/supersonic issue matters much at handgun ranges.
