Have been reloading 9mm for the C9 and found a perfect load for it. Then just had to get a 995TS. Those oh so perfect loads in the C9 magically morphed into the worst jamming ammo known to man. Wanted to blame the 995 because how could this perfect round in the C9 cause such problems in the 995? Got 2 boxes of Blazer Brass and back to the range for testing. 200 rounds of BB and no jams. Switched back to my reloads and 3 jams the 1st mag.

So back to the drawing board (bench) to tweak a load for the 995. Sounds frustrating but only if you let it be. Experimenting is half the fun, otherwise reloading would just be cookbook monotony. All those variables like powder burn rate, charge weight, OAL, etc will now be more fully explored and understood.

I was frustrated that a factory turned out mass produced ammo that would work in both and I didn't. I will though, and soon. :embarrassed2:

I know what you mean. The though of making ammoe specific for each firearm annoys me as well.

 

[Silicon Wolverine]

lenghten the OAL and go to a slower burning powder and youll gain some ground.

SW, thanks for the good advice.

Makes me feel better that you are encouraging me to do what I was working on doing. Nice to know that I'm not stuck out here all alone. I have already increased OAL, and will try upping the charge and see what those 2 changes do. If I'm not satisfied then I'll begin working with different powders. Increasing OAL and increase in charge are the least expensive options to try first.

Hey man, it's nothing but time. It's not like we don't have plenty of it huh?

 

[2TN Mules]

LOL, so true Primal, but after i passed 50 the clock does tick faster.

Blues are clearing up though. Spent last night researching and reading. Increased charge and OAL on 20 test rounds today. All the problems magically cleared up. :yay!: :yes:Going to bump the charge up another .2g and load them tonight for a trial tomorrow. Then I'll need to see how the C9 likes these? Would really like to stick with one load for both to reduce errors and compensate for my laziness. :embarrassed2:

i ended up with dedicated carbine loads to run 100%. plus i could run a powder that was way too slow for pistols but just right for the carbine.

[2TN Mules]

I imagine your right SW and a dedicated load will be what I end up going with? Will have to see :brow:

 

[Silicon Wolverine]

i spent weeks working on a load that would function in both 100% and came to the conclusion it was impossible. my pistol load runs 100% in my HP. glock, SIG and dads hi power. my carbine load works in my carbine only. kinda like shooting 223 out of a 6" barrel pistol AR or a 16" barrel thompson center. it has to be loaded different to get the best of its potential.

Not to intrude where I don't know much as I don't even have a 9mm, but why does the factory load work in both? Is it a compromise that works to the least advantage of both guns? so its functions both but they lose ..what?..accuracy? fps? Just curious and you probably know SW, so maybe you can expalin it to a layman such as myself. If that is the case, that would seem to make loading specific to weapon well worth it to me, getting something that factory ammo can't possibly give you even at a higher price.

 

[2TN Mules]

Factory loads are like a "1 size fit all" garment. Everyone casn get in it but it doesn't fit everyone very well. Customizing your loads for specific applications will always result in better ammo than factory ammo.

 

[Silicon Wolverine]

the factory ammo is designed and loaded to give optimal performance in a handgun as thats its intended purpose and 95% of usage. when you use pistol ammo in a carbine the longer barrel changes the pressure-over-time curve. what you lose is velocity as they have to download the ammo so the pressure dont get too high if its used in a carbine. thats why most +P ammo says "not for use in carbines" in the safety notes that no one reads.

at one time black hills did a short run of carbine specific 9mm (designed to be used in colt ar style 9mm submachine guns) but i only ever found one box of overrun, the rest was sold to LEOs i was told.

Howdy. I'm new around here but I'm experiencing some 9mm carbine reloading problems too. Out of curiosity, what size bullet are you using for your loads? I was attempting to use the 147gr Speer GDHP and was having nothing but problems.

First, the case developed a decent size bulge at the base of the seated bullet and this would prevent the cartridge from fitting all of the way into the chamber. I increased the OAL and the bulge reduced enough that the problem resolved.

The next problem had to do with the magazine. The cartridges would tilt downwards or get hung up in the magazine preventing them from being fed into the gun. This did not involve the feed lips, but the magazine body itself. I reduced the OAL down in increments until the above mentioned bulge reappeared, all with no luck.


Thanks! ^-^

147 GDHP are designed for use in pistols for the most part. ive never run them in a carbine with any luck. try starting with 115gr FMJ and see where that gets you.

Tony673,

Silicon Wolverine is the expert reloader for 9mm carbine ammo. I'm just now getting mine figured out as you see from this post. My problems were caused by 2 things that I've discovered so far, to light a powder charge and to short an OAL. The C9 loved it but the 995 hated it. After research I increased the powder charge and OAL and problems disappeared. I'm loading a 124g LRN boolit that I cast from a Lee mold. It is what I'll be using. I have not experienced any bulged cases with using the Lee 9mm carbide die set with factory crimp die. I use a cartridge gage to check samples of each batch. So far I've had no magazine problems but I always tap the mags to seat and realign the rounds, old habit.

 

[Silicon Wolverine]

i use a FCD as well for 9mm.

the long bullet length of a 147 gr often makes for problems in 9mm due to its short case length. ive stopped using them in any of my reloads as i could not assure feeding 100% with them even using a FCD. if i want 147s (pretty rare anymore) i buy them in factory loads. i use 115 gr FMj and 124 gr cast bullets for 99% of the shooting i do.

for my carbine i settled on blue dot powder. it gives me the most consistent velocity and best accuracy. it is dirtier than other brands but with no gas ssystem to worry about, who cares if the barrel is alittel sooty?

Good info and thanks for the replies. I'm headed to my local reloading supply store tomorrow, so I'll look into some 115gr bullets.

Thanks again for the help!
