chapperz1991 Posted May 23, 2011 Report Share Posted May 23, 2011 i have just purchased a webley & scott bolt action .410, on the barrel it is stamped as having a service pressure of 3 1/4 tons per square inch.(chambered 2 1/2 inch) i was given with the gun a free box of eley fourlong game cartridges, shot size 6, on the side of the box it says for use only in barrels chambered for a service pressure of at least 3 1/2 tons per square inch? advise much appreciated. paul.

njc110381 Posted May 23, 2011 Report Share Posted May 23, 2011 Hmm, not sure what to advise here. You'd think that if it was proofed to take any 2.5" cartridge but it seems not? I wonder if the Eley's are a higher pressure than other makes? Somehow I doubt it? I'll sit back and read the replies to this with great interest.....

decoy1979 Posted May 23, 2011 Report Share Posted May 23, 2011 I was first introduced to shooting with my fathers old bolt action Webley & Scott 410. Eley Fourlong were the main cartridge I used first in paper case and later in plastic. I certainly never encountered and problems although I would have to get my father to check the gun to see what pressure it is stamped at. Can't see any issues personally, but better safe than sorry.

wymberley Posted May 23, 2011 Report Share Posted May 23, 2011 (edited) Don't think that there's lack of interest here, it's more like everyone is baffled. Certainly, Andy's link was beyond my comprehension. I seem to remember that 3 imperial service pressure equated to 850 metric proof pressure and similarly, 3 1/4 to 900. Emphasis here is on seem to remember, ie, flawed! Suffice to say, you're being sensible and I wouldn't poop any off until it's resolved for sure. Edit: Think I was right, my memory is flawed. I think it more likely that the service/proof pressure equivalents were as now shown. Biggest mistake was throwing away a pre 1989 Eley diary - that would have solved the problem immediately. Something seems to be not right and for my tuppence worth, I,m going for the cartridges on the grounds that 3 1/2 tons does not seem right for a 2 1/2" cartridge which is what a Fourlong is and excessive for a 2 1/2" chamber. 2nd Edit: OK, this has been getting on my wick, so with nowt better to do I've had a search. Have only come up with one possibility and even then I think the author is possibly talking rubbish. I regret that I'm not very computor literate so it may just be easier to ask if you could measure the length one of those cartridges (unshot) and is it a RTO or crimp closure?

The case length unfired is 56mm. RTO? sorry i dont know what that means, what i can tell you is that in the end of the cartridge it is cardboard with 6 written. thanks for you advice.

chapperz1991 Posted May 24, 2011 Author Report Share Posted May 24, 2011 (edited) Is there owt about pressures on the cartridge box? it says on the box " for use only in guns with 2 1/2 in/65mm or longer chambers marked for a service pressure of at least 3 1/2 tons per square inch or a european proff pressure of 900kg per square cm. and/or a shot load of 7/16. use only in nitro prooved guns, if in doubt consult your gunsmith or proof house" my gun has on it 3 1/4tons per square inch. it also has on it stamped one on the barrel and once on the bolt bnp? paul.

wymberley Posted May 24, 2011 Report Share Posted May 24, 2011 it says on the box " for use only in guns with 2 1/2 in/65mm or longer chambers marked for a service pressure of at least 3 1/2 tons per square inch or a european proff pressure of 900kg per square cm. and/or a shot load of 7/16. use only in nitro prooved guns, if in doubt consult your gunsmith or proof house" my gun has on it 3 1/4tons per square inch. it also has on it stamped one on the barrel and once on the bolt bnp? paul. Oops, sorry,mate, I was asking Shooter in case he was using something different. OK, your cartridges are, as you already know, fourlongs, ie 2 1/2" with a Rolled Turn Over (RTO). Someone on another forum says he is using magnum fourlongs. Now, if these actually existed that would explain 3 1/2 tons. Your original post didn't say from where you got the gun so I was wondering if these of yours were an older box and of a load no longer in production. This now is obviously not the case and the chappie on the other forum is talking rot and is actually using the 3" magnum - extra long is it? Consequently, I would just check with the RFD and see what he has to say. I still remain with the cartridge, or more precisely the packaging, being the problem as as has already been shown, the 900 bar usually relates to 3 1/4 tons/sq" If you do chat to the RFD, it would be good to know what he says.
