hp01mp Posted December 3, 2013 Report Share Posted December 3, 2013 Not sure whether this has been covered before but I haven't quite been able to find the answer in previous posts... I was wondering whether the length of your chambers should dictate the ideal length of the cartridge you use. I'm not talking so much about using the wrong shell in your gun as you would be if you tried to fire a 70mm shell in a sxs with 2.5'' chambers! I'm talking more about whether generally speaking a 3'' shell would give less recoil and pattern better from a gun with 3'' chambers than a shell with the same load in a 67mm case. I have an o/u with 3'' chambers and I am wondering whether there's any difference in buying 32g 5's in a 67mm case or 32g 5's in a 70mm case. Would one be expected to perform better assuming that they are from the same manafacturer and there's no difference in the powders used? Thanks Quote Link to comment Share on other sites More sharing options...
fenboy Posted December 3, 2013 Report Share Posted December 3, 2013 In a word no , there is no advantage to only using the same length cartridge as you chamber . In fact I can think of plenty of reasons not to , I for instance shoot a gun with a 3.5 " chamber , it would be a very painful and expensive to put a couple of hundred of those through in a day at pigeon !!!!

Thanks i get what you are saying, i like good classic loads at low speed and bigger shot. 2.5" can shoot 36g loads as long as the gun is proofed to that standard.....

hp01mp Posted December 4, 2013 Author Report Share Posted December 4, 2013 That's exactly what I'm getting at! I'm moving away from Eley cartridges and trying to find an alternative shell in 30g 6 for general shooting and another in 32g 5 for late season stuff. I have tried Hull High Pheasant Extreme in 32g 6 (actually 5.5) and they are great, but just too punchy for general use. I was therefore going to go for Hull Imperial Game 30g 6 (presumably a little softer to shoot than High Pheasant in the same load) but I'm wondering whether really I should be going for the 67mm shell rather than the 65mm bacause of the length of my chambers. I suppose with chambers that can handle any cartridge length the only advantage in using the same load and shot size in a 70mm case is the few extra pellets it provides?

The same load and shot size in a longer case will not give more pellets , a 2 1/2 " case with 30 grams of 6 shot will have exactly the same amount of pellets as a 2 3/4 " case with the same load. If you are shooting a O/U or S/S gun then it will not matter at all what case you use as long as it is not longer than your chamber . Autos are slightly different and can suffer loading jams with the shorter cases. Quote Link to comment Share on other sites More sharing options...
matone Posted December 4, 2013 Report Share Posted December 4, 2013 65/67mm loads are usually going to be softer to shoot ,as they are loaded to a lower working pressure. Quote Link to comment Share on other sites More sharing options...
HDAV Posted December 4, 2013 Report Share Posted December 4, 2013 More important than the length is the load, powder wad and primer used. What eley where you finding too punchy? VIP? Quote Link to comment Share on other sites More sharing options...
hp01mp Posted December 4, 2013 Author Report Share Posted December 4, 2013 Thanks, this is exactly the sort of info I was after. I have used Eley Grand Prix for ages. I have gone off them not because they are punchy but because of quality issues. I had a bad batch with loads of swollen shells earlier in the year and then the very next batch of Eleys I bought had hard primers - the latter really wasn't funny when it led to a a couple of misfires at a field trial where there were hardly any birds put up, very embarrassing actually. So basically I have lost faith with Eley. I even sent back samples of the cartridges (at their request) but they never bothered to come back to me. Actually very sorry to be giving up on the Grand Prix's but I do like my cartridges to go off when I pull the trigger and not need jamming into the chambers! Everyone seems to be raving about Hull at the moment so I will try their Imperial Game 30g 6 as I like to shoot the smoothest shells I can get with the required load . I did try Three Crowns a while back but couldn't get on with them - we shall see. Quote Link to comment Share on other sites More sharing options...

Seems strange that 2 1/2 " chambered guns are proofed for a lower working pressure ! Quote Link to comment Share on other sites More sharing options...
