RAMI nose dives from mags

[jack76590]

Shot the RAMI with a different more rounded bullet profile today and it ran without any issues. Here's where it gets interesting though. I re-tried the offending flat nose conical hollow point rounds that were the perceived culprit on prior outings and the RAMI ate those too without any stoppages. It digested over a hundred of them in different magazines even the older ones that I thought may have been causing the issue. Go figure.  Some days things just don't make any sense. On a positive note the RAMI has a new recoil assembly and extended mag courtesy of CGW. I guess I will continue to avoid the conical bullets and stick with a more rounded bullet profile but it's mind boggling that now I can't reproduce the issue with the offending bullets.   

It could be the new recoil spring, which might be stronger. Or it could be the pistol is getting broken in.

^^^^^ probably the new recoil spring. If they didn?t feed prior to the new one, and they feed fine after the new one,....... See where I?m going with this

Re-read the original post. The gun is not just getting broken in. It is 12 years old and has had thousands of rounds down the pipe. The gun previously ran fine then started having issues so the recoil assembly was replaced and a new mag was purchased to see if the issue would subside. The gun was then taken to the range and shot with the new mag and recoil assembly and the nose diving was still occurring. The pics in the original post with the nose dived round (which kept occurring every 4-5 rounds) was with the new magazine and new guide rod assembly installed. I took the RAMI back to the range yesterday and shot it extensively with a more rounded profile bullet which worked just fine so I decided to try the conical bullet (the problem child) and it also ran just fine. I also shot it with the older magazines and it still ate everything it was fed. I am going to stick with the more rounded profile bullet and avoid the conical bullet in the RAMI to avoid any future issues.

Sorry, missed that. Was just trying to be positive.

No need to apologize. I hope I did not come across as an "azz".

[cntrydawwwg]

Nope sure didn?t. It?s all good.
   Isn?t the first time I posted without fully reading first.

I wonder if you had a batch of your hand loads (with the conical bullets) that were just a hair LONGER (OAL) than the ones you've used since then?   

It could still have been a bullet-related issue, but more than the bullet alone was causing the problem.

I suppose that could be possible but is highly unlikely. I use a Dillon 550, the tool heads stay pre-set and I meticulously check OAL, crimp diameter, powder charge, etc. etc. when I begin reloading and at various intervals. One factor that may be more likely would be case length as I do not trim pistol cases. At this point it is a "head scratcher"; I'll continue to shoot and monitor and see what happens.

After getting my new Rami,I took it out to my local range and put several hundred rounds of assorted ball ammo and it ran flawlessly. I went back to the same range but this time their normal ball rounds (BlazerBrass)were unavailable and I had to settle for Armscor JHP.  I racked  the slide and fired one round and got a malfunction. The gun would not go into battery. It stayed open approximately 2to 3 mm and no mount of pushing to get it into battery or pulling on the slide would release the round. The slide was frozen. I was finally able to work a small jewelers screwdriver into the separation and separate the bullet from the casing. I then had the problem of dislodging the bullet in the barrel and that was accomplished with a small flat pencil and a hammer.  I assumed that this was a one of a kind problem and tried twice more to get the gun to fire the ammunition. Both times the exact same scenario as previously described happened on the first round. Went back to the house and got some of my Aquila as well as my Underwood Defendor rounds and both worked flawlessly once more.  Went back to my dealer and he polished up the ramp and examined the gun and was able to fire several JHP rounds. I assumed it was fixed and yesterday went back to my range and asked for the same Armscor ammo and the entire scenario returned once again. I know the easiest thing is to avoid that ammunition but my concern is that when I need the gun to go bang it won?t. Should I leave well enough alone or send it back to CZ?

[Walt Sherrill]

If you ONLY have that problem with one brand of ammunition, I wouldn't send it back to CZ.  It sounds as though the ammo you were using is out of spec.  (Compare the length of those rounds to some of the other "ball" ammo you have or can easily access.)

At different times over the years, some of the "compact" CZs had rifling that extended closer to the chamber than was appropriate.  Tha area is called the freebore and if its too short, the rounds might engage the rifling before the gun is closed.  THAT COULD be a problem with your gun.  (I've not heard of that happening with RAMIs, but I don't pay a lot of attention to posts about that model.)

Many thanks!

I just made a thread on increased power recoil springs Ive been testing out over the past year.  When I first got my rami I had a few nose dives.  Ever since I started using the increased power springs i havent had a single malfunction.

If you meant extra power MAGAZINE springs (not recoil springs) that makes sense.  If you meant "recoil" springs, I don't understand why that would have any effect on nose-diving rounds.  (But I'll be the first to admit that there's a lot about guns I don't understand.)

[charlestheforth]

youre right.  I guess a real nosedive malfunction is where the bullet dives below the feedramp, and no amount of pushing it forward will put it into battery.  I've just become accustomed to using that term as a catch all for when the bullet gets hung up on the feedramp.  I had a few malfunctions after around 500 rounds through my rami where a good whack on the back of the slide would chamber the round, the increased power recoil springs eliminated those.  sounds like thats not the same problem youre experiencing though. 
Good luck, I hope you get it straightened out!

The way you've DESCRIBED the problem this time sounds as though the recoil spring wasn't strong enough to retain enough force to feed the next round.  In that case, your solution was the proper one.  What you described was a weak (or weakening) recoil spring.  As long as what you've done works, the problem is solved.  If you roll your own, changing loads can have the same positive or negative effect.
