I think Federal has 3 types of branding for their JHPs, HydraShok (with the post), HST, and Hi-Shok (looks like HydraShok w/o post). Not sure if they still make the latter, but I saw a couple of boxes on the shelf last year at WW. Could have been old stock though.
I recently tested several boxes of new Hydra-Shock in my trusted Commander. This had been my carry load for over a decade with total reliability. SOMETHING has changed, IMHO.
The bullet hung on the feed ramp and the slide overrode the case...giving a bullet up stoppage.
This happened several times. I was using proven Wilson Model 47 magazines.
Prior to the latest stoppage, on this range trip, I fired about 100 rounds of vaious handloads and JHP's with ZERO problems, then the Hydra-Shock issue, I fired 100 trouble free rounds of other ammo AFTER the failure with no stoppages.
Like I said, somthing has changed.
I'm definitely going to a different load and will buy it by the case to avoid manufacturer's changes and "improvements".
This just points out that just because one load has worked well in your carry gun it doesn't mean the next box will. Hence, the "buy it in case lots" recommendation.
I know what you mean. I've used Hydra-Shock for a decade with ZERO issues. Now this...
Unfortunately, I have none of my old stuff left to compare the "new" ammo too.
Shocked the dog doo out of me, to say the least.
