Short carts in a semi-auto

[Wookie]

I've just seen the size of the cartridges that i am putting through my Urika 2 and i have a pretty serious question to ask.

 

They are Eley Realtree 6.5s in a 67.5mm cartridge and my Urika's chambered for 76mm/3" carts. Is this going to cause any problems for my shotgun in any way? The last thing i want to do is damage it by putting carts that are a half inch shorter than it really should have.

 

i've only put about 40 shots of it through the gun if that's any help.

 

cheers

No you will do no harm as modern chamber's taper down now rather than just stop.What you should not do is put any bigger than 3" (76mm) ie 3.1/2" down it you will be ok with the 3" stuff & down to your 2.1/2" cartridges.

As long as the shell is shorter than the maximum allowed case length the gun will be fine. I use 67.5mm shells in my xtrema which is chambered upto 3.5 inch without a problem. Some say the pattern can suffer slightly, but I prefer to admit my misses are down to my poor standard of marksmanship! Sometimes an auto can be fussy about cycling such a short case (don't ask me why) but if they work for you then it's fine to use them.

My Browning A5 is chambered for 70mm cases, when I first got it I tried using shorter 65mm, & found they wouldn't recycle well, sometimes firing two off in quick burst & the third jamming in the ejection port.

 

Stepping up to the 70mm solved it though, trial & error,

The long recoil Browning with that BIG heavy operating spring round the chamber will do that with some shells; the hammer does not travel the whole arc to engage in the sear; the new shell sits on the carrier and gets 'fed' into the chamber by the bolt - followed by the hammer which is in contact with striker - which is in contact with the primer head and BANG! (or should I say 'B-BANG!') Nasty!

 

 

With a gas-operated shotgun, which begins to cycle AFTER the shot is about a foot up the barrel, double discharge is rare. I (and many of my pigeon shooting mates) regularly use 50mm (2") rolled turnover 28gram reloads in our Berettas and Remingtons. (The pigeons don't like 'em!)

Thanks for the reassurance guys! I appreciate i sound like an old woman, but it's just that the gun is still so new and i love it dearly!

 

Mungler... Good advice that, i'll try and remember it! *grin*

I have sad memories of the Browning long-recoil. The primer/striker/hammer are all in contact and if you have a 'missfire' there is a chain of events that can lead to a discharge while removing the faulty shell. My late father was the victim of this chain and was crippled. 'Nuff said.

 

Be careful!
