I have used my Lee carbide pistol dies for the past 6 months and have loaded in excess of 1000 rounds with no issues.

I switched to AIM 124 g copper plated from my previous BDX 124's. Last time I loaded the AIM I ran about 200 rounds and had one bullet stick inside the seating die. I backed the bullet out and continued loading several more rounds without another sticking.

Today I had loaded about 130 cartridges with the AIM bullets and it started to jam the bullets inside the die again. I took the die apart, looks fine, cleaned it with alcohol and continued to load. It loaded two more rounds and then started jamming, jamming, jamming. Finally gave up.

Has anyone experienced this problem with Lee or other dies and if so is there a solution you can share?
 
Is it possible that the aim bullets are oval or oversize(ie >.356). This jamming happened to me while trying to seat .358 cast bullets(my P85 bore is way oversize and leads like crazy). good luck
 
dont worry its not only you whos having this problem, i went back to Zero and Mont. Gold.its a little pricey, but trouble free, Had the chance to try a few rounds of Berrys, last week, . If your okay with plated bullets, you wont get wrong with Berrys, very consistent in size,never had a problem, I did not even made adjustment og my die except for the OAL
 
Was loading Frontier 9mm 147's with Lee dies with no problem. Switched to CamPro 147's and they started to stick in my seating die. Bought a Redding micrometer precision seating die and the problem went away.
 
Well I cleaned the die this morning and saw a bit of residual brass or copper plating on the rag but was only able to get three rounds through before it jammed again.

This afternoon I picked up some BDX 124 copper plated bullets that look identical to the AIM projectiles that are sticking.

Loaded 10 rounds (limited time) of BDX with absolutely no issues or problems. Stuck an AIM in the hole and it plugged. They both mic out at .355 but the BDX bullets seem shinier, slippier, smoother.

Never lubed pistol bullets before so not sure how to do up a bulk bunch??

Open for suggestions?

I have had the exact same problem with a box of AIM 124gr.I also checked a bunch of them and they were all 355. I dont know what the problem is and have never had this issue with any other bullets,lead or copper. Also these bullets on a scale come in at 122gr not 124gr. If i have to lube a plated bullet to make it work something is wrong and it isn't my dies.
 
It sounds like you are using the Lee crimping die in the station after the seating die. If so, try screwing in the seating die so that it puts a very light crimp on the case as it is seating the bullet. This might stop the bullet from sticking in the die as the case will pull it out because of the neck tension on the bullet. Also it will go into the crimp die much easier with the bell removed. (As I have found out on my press). This will only work if your seating die is the Lee combo seating/crimp die.

Lee strikes again!
 
I have loaded a few thousand Aim 124 grs, among other brands with my Lee dies. Never experienced this problem. Maybe the cases are slightly over belled and not providing enough neck tension causing the bullets to be plucked from the cases as they are extracted from the die.

Are they plated or Jacketed? I wasn't aware that BDX was making plated bullets.

The BDX (Jacketed) are .3555
The Aim 124's (Plated) are .356

I use AIM 124's, no issues (Dillon dies)
 
Could be the seating stem shape that doesn't fit the contour of the bullet. Similar thing happened with my buddys die set and the die manufacturer told him to send a few bullets (just so happen to be BDX) and they made him a custom seating stem for somethink like $15-20.
 
A buddy of mine....his pistol will not completely chamber 147gr 9mm AIM bullets regardless of OAL....Any other bullet we tried works fine,but AIM bullets dont work..go figure

What's crimp at? Oversized in diameter bullet may cause it easily.

What generation are the bullets?...

I had feeding issues with the Generation 2 124's...it was a very common complaint. Aim changed the profile for the Generation 3...and I haven't had any issues since...

I've had very good luck with the Aim bullets...and good accuracy (out of an Open gun at about 1350 fps)

I believe they also re-profiled the 147's.

If anyone is having issues...call Rob or Bill. They'll help you out.
 
Well he did buy the bullets at a P.G gun show(old stock?)And I do belieive that the bullet profile is an issue...BUT....I also think that his pistol Might have a shorter throat than most.S&W MP..reguardless,they work fine out of my CZ...AND...no one else he shoots with has a problem with those bullets(a different lot#?)

I thought of that but why would the first 200 rounds work perfectly and then in the second loading session work just fine for the first 135 rounds and then start to jam?
 
I had the exact same problem with my M&P. Seems the throat is really short and it goesn't like the shape of the bullets. Had trouble chambering loaded rounds. I ended up seating them down quite short, 1.075 and have had no troubles since. The bullets I was using are old stock, and measure .356. As others have said, I think they are all .355 now and hopefully the new ones will work fine.
