Does anybody use reloads in theirs? I made some with 3.9 grains of 231, used Aim projectiles copper plated bullets, and the bullet seems too large and jams in the chamber. I used an oal of 1.110 and the bullet gets stuck before it can fully seat. The same reload fits in a barrel from a different gun just fine. Should I try another brand?

Thanks

The AIM 124 gr bullets are to long in the shank. I used the load you are using and the OAL and they would not feed into the Shadow. The CZ have very short leads. What is happening is the bullet olgive is hitting the rifling before the cartridge is fully seated in the chamber. The bullets will work in the M&P loaded to 1.10 but won't work in the Shadow at that length. I would not recommend loading them to a shorter length. I did and found I was getting high pressure signs ie flat primers and evidence of primer flow around the firing pin indentation. I think these bullets are designed more for the .38Super than the 9MM.

I have used Can-Pro and Berry plated with good success in my Shadow. OAL 1.110

cam Pro, Berry's, BDX and Speer if you can get them....all work well in the Shadows and tanfoglio's.
 
Yes, I had that problem with some bullets when reloading for CZ. When I used AIM 124gr I think I seat the bullet to 1.10" and it worked fine. When I used Berrys 147gr I could get away loading a bit longer and it worked fine.

No pressure signs.
I have since moved to 147's though.
 
Hi there..

I had the same thing happen to me with Aim bullets in my Tanfoglio Match in 9mm.. although they were the 147 grain variety.. Bought 5 k of them.. loaded 100 and i could not get them to chamber.. Just sold them to a buddy (for a loss btw, Thanks Aim) and he used them in his Sig... I have since gone to Berry's 147 grain plated... and they work well.

I load AIM to 1.100 and never had any issues. Both 124 and 147

If you were dissatisfied you could have simply called Aim and asked for a refund. I'm certain you would have been given one instantly. Alternatively, you could have asked for loading data for that bullet. You would have been given that too.

You have to adjust your loads to your gun. Many CZ's are chambered short. Adjust your oal length until it just clears the rifling, adjust your charge throw downwards accordingly and work up with a chrono to accurately hit your target power factor. If it feeds and functions correctly in your gun and doesn't show pressure signs you have the correct load recipe and length for your gun. If after that it really doesn't work for you, then it doesn't work for you.

I have seen examples of loads with these bullets that had no pressure issues and I have seen loads that had horrendous pressure issues, but these were easily corrected. I have also seen people using loads made with other bullets and showing huge pressure signs with the shooter not even realizing it. I've seen too short, too long, over-crimped, under-crimped, under-sized, mangled primers....everything. Everyone blames the bullet. For reference: These bullets were designed to work with 9mm AND .38 Super, and they do...if you do your homework. With ANY new load recipe you must proceed with caution. You're dealing with explosives after all.

Anyone with questions feel free to contact me. I'll be happy to help.

Had similar problem with my CZ 85C. It seems like OAL is critical with most CZ pistols. I am buying reloads and will soon be reloading. Conicals are better than RN. SWCs feeds similar to Conicals but the shoulder might create poor feed if OAL is not checked before seating and crimping the bullet.
 
it's NOT the bullet , you have to fit a dummy to your chamber , this is a std proceedure for any reloading , pistol/rifle . my shadow , sig clone , para , s&w 39 , all work with any bullet , inc: aim , berry's , drg , rainier , redline , etc.

It is the bullet in this case. The bullet has a very long shank and a stubby olgive. When loaded to 1.10 the OAL of the cartridge was to long for my chamber and cartridge simply wouldn't seat in the chamber. At 1.06 the cartridge seated fine but was when fired there were obvious pressure signs. The bullet worked fine in my M&P at 1.10 though. The M&P has a more generous lead. The CZ's typically don't have long leads. I believe the bullet is more designed for the .38Super than the 9MM. The actual bullet weight varied somewhat from 121 gr to 123 gr.

Take care

Holy crap everyone loads short.

I have had zero issues with the bullets I stated earlier at 1.135. I have shot those rounds out of 2 different shadows (mine and a friends).

1.087 seems really short to me. Are there any signs of over pressure.

I have loaded many different varieties of bullets for my Tanfoglio Match 9mm and they all worked too.. only had issue with those AIM projectiles... I load all my 9mm projectiles (147 gr) long at 1.135" as the barrel is throated to allow this, also has polygonal rifling. I also use VV N320 as a powder which gives a soft shooting load.

I tried to get those 147 gr Aim projectiles to chamber properly and just could not.. IIRC they were all .356. I guess my barrel has a tight chamber. I usually make dummy rounds with new bullets and chamber check them with the barrel just did not in this case as i have been loading 9 mm for a few years now. They worked well for my buddy in his Sig.. no issues at all.. At the time i did not want the hassle of shipping them back so i just sold them.. Sorry if my comment irked you.. my apologies..

On a positive note... I do like your AIM 185 grain 40 S&W projectiles .. They perform very well in my Tanfoglio Limited Custom II ...

Both of my CZ 75B's hated the Aim Bullets. Had to load them down to 1.085 OAL to get them to chamber and experienced some high pressure signs. So I fed them to my Beretta instead, where I loaded them to 1.125 OAL, no problems.
