wonky cartridge


Recommended Posts

had a bit of a problem the other day with a cartridge that would not chamber, I was using the sxs so I just pulled it out and inspected and it had a bulge on the side. if this was in the semi I think it would have been a day ender trying to get it out!

 

Does this thing happen often? only shot a couple of thousand so far so should I keep a eye on things?

 

Should I open it up and see whats happened?

Tipped wad, reloader s get them more often on the progressive machine, usually caused by the old crimp protruding into the inside of the wad guide thru the fingers, more so with 6 star crimps, (one of the reasons the USA went 8 star.) But it does happen with factory loads as well on new cases, even skived ones.

welll the results of the autopsy are the overshot card? did go in at a angle and caused it to bulge out when the wad was put in, the wad is not in too bad condition but the card is pretty mullered! Learn something new every day.

The sensor on the powder card punch wasn't set correctly, it stops the machine when a missing or tilted card is detected. The failsafe rail on the packing machine wasn't set correctly, that will also stop the machine. You've also got a scorched wad from either a blunt cutter, hard board or no wax!!

RC 3 inch lead shell can also cause a problem with semi autos. They squeeze a big load into a 3 inch shell and some of the pellets cause small bulges in the side of the case. These usualy will not cycle after a shot.

My Dark Storm had pellets sticking out the case, so when in haste of reloading on the drive it was stuck and a pain to get out out.

Shot bulge comes from not pushing the wad or wads hard enough to give enough space in the cartridge for the shot. Then when the crimp and turnover are formed in the machine the shot only has one way to go and that's out to the walls of the tube and not down. On BSN loading machines this error can be found as they roll down the packer.

But only if it's set right !!

Probably done on the same machine, with the same faults.

Graham, I would have thought the shell should have been 'lifted' by the gauge, thus stopping the machine before the shell went to the printer.

Sensors poorly set or wear?

Alan. The failsafe would be the top rail on the packer as they come from the printer. If that's set right then the operator can remove the offending shell and replace keeping the orientation and without any down time on the machine. Either of those cartridges could probably been picked up by the sensors on either the card punch or shot punch whilst the machine was running.

The 3mm cards were the worst to load fast, and that was the best way of finding a tilted card without the machine stopping.

Considering the huge amount of cartridges that the manufactures make it is surely inevitable that a few get through the system.

 

I disagree

when you are dealing with something as critical as shotgun cartridge the QC should pick up something that is not fit for purpose

 

I can't tell you how many 20g Eley cartridges I had which had shot bulges and either didnt chamber at all or went in stiff

 

stopped buying Eley as a result as they appeared to not give two hoots as to my concerns or the bigger problem with their QC

Do you actually believe there should be absolutely no damaged shells getting through? I think the price would rise dramatically if quality control was tightened up.

 

Over the years I have used shells by various manufacturers, of these Winchester were probably the worst offender with regard to odd shaped cartridges.

 

I have used a small amount of Eley shells, but mainly Gamebore, Hull, Rio, Victory and lately I have been using Proper Catridges. All of these have been very good with regard to their shape and fit in the chamber.
