Weird jam

[Dave Waits]

Stijn, I'm sorry I wasn't clear in my post. What I wanted was for you to remove the barrel, hold it chamber-end straight up and drop a round in.

As for your OALs, you want to run as long as you can. I run everything at 1.265 with a .470-.472" crimp(I don't use swcs). I think your LSWC are correct, that's why you never had any problem with them.

Try this, run a small batch of your 230grain reloads at 1.265. Let me know if they feed for you, I think your rounds may be too short because your magazine has long feedlips.

Stijn, and everybody else who reloads; Remember, the 1911 was designed to feed FMJ rounds at 1.265 OAL. With any round you load, the closer to that length you are, the better it will feed unless you're using Wadcutter magazines. These are easy to spot as the feedlips are very short compared to a standard or even a hybrid magazine feedlip.

I kinda haven't got much 230 grain ball left to load and them LSWC's are 50% cheaper (and great for 25 meter bullseye).

Got me a case of 1000 Mag Tech 230 grain FMJ ball on the way, i i think i'll stick with the 200 grain LSWC's for practice and volume, and keep the factory stuff for zombies and for rapidfire/double tap practice (i prefer factory for rapid fire).

Got about 30-40 of them HN 230 grain reloads left, i'll run em through next weekend. Then factory ball only.

I made about 500 of them LSWC's last weekend, so i'll see how that works , i doubt i'll get the issue again with those and if i do, i'll have a few more things to look at and i'll keep the bullet that initiated the jam for analysis.

Many thanks for the tips so far, even though the troubleshoot isn't conclusive yet, it's been a great help.
Will post my results on the next visit to the range.

Went to the range, shot about 60 200 grain LSWC, couple of mags Fiocchi Ball,
Then the last 20 of them 230 grain loads i think caused the previous jams.

Either way , no jam today..

Then i ran through a box of 50 Mag Tech, 200 grain LSWC
And i mean ran through, rapid fire, just letting her rip with 5 mags filled to the max. 8 rds each...

My oh my, that Mag Tech ammo is fire and brimstone, i'm talking big boom, plenty of sparks and smoke coming out the front end it wasn't pretty.

but the gun did not jam


At this point i'm convinced that the gun is not the cause, there must have been something wrong with one of those reloads.. I just don't know what, nor do i understand the mechanics of the failure/jam.

I did get me a shooting chrony, so i can measure my loads, better quality control.
To bad it didn't work with the indoor lighting @ the range, fluorescent lights
should have read the manual before hand.. gonna find me some LED strips to put on the diffusor, that ougtta do the trick.
