147 grain Hydra-shocks don't like feeding in my CZ-75BD

It seems that the 147 grain Hydrashocks consistently get hung up on the feed ramp in my CZ-75BD. It's a relatively new pistol, with about 1000 to 1200 rounds through it. I clean it very thoroughly every ~250 rounds, and yes, the feed ramp is totally clean.

Winchester 115g FMJ "target" rounds from the 100/$10.96 boxes at Walmart feed perfectly in this gun, as do all varieties of 115g JHP ammo.

Has anyone else seen this problem? Should I switch to the 124g Hydrashocks (or speer Gold Dots) for practical self defense use?
 
I've had that happen with other 9 mm pistols. Lighter loads seem to work more consistantly. Maybe it the the OAL? At the time, I didn't have the tools.
BTW, are you The Walrus, from the Beetles song?
 
Try a lighter weight bullet. My Sig 226 does not like 147 grainers, and often gets hung up with them. All other bullet weights feed fine in my 226. So, when you have problems just keep trying other ammo and eventually you should find one that works best.

The 115 grain and 124 grain bullets traditionally work fine in my Sig. YMMV
 
For some reason, my MP5 doesn't like the 147 gr. Hydrashocks either. Just refuse to slide up the ramp. Other 147 gr. subsonic loads work just fine.

With just a particular magazine, or all of them?

Some European designed (originally) pistols don't function as smoothly with the longer 147gr rounds as they do with the shorter 115, 123 & 124gr rounds. Sometimes it's been an OAL issue, and sometimes it's been found to be a recoil impulse/recoil spring calibration issue ... and sometimes it's other things ...

If you're devoted to that particular round, maybe an armorer familiar with that platform might be able to diagnose the problem and resolve it with different magazines, a different weight recoil spring calibrated to your ammunition choice, an adjustment to the extractor hook profile and/or tension (been there & done that with one particular, but nameless, American ammunition manufacturer for a single production line of ammunition) ... that sort of thing ... and do it so that overall reliability with other ammunition isn't compromised by the "cure". Anybody here ever have THAT experience? ... and don't everybody hold up your hand all at once ...

On the other hand, if you're not limited to that round for work reasons, and aren't inclined to have the mystery solved ... find one or more loads that do function 100% in your pistol and invest in them ...
