propercartridges Posted February 1, 2019 Report Share Posted February 1, 2019 well as per title i get asked about 3 inch chambers on 2 and 3 quarter cartridges does that missing quarter of inch make a difference on fibre i through the question open to you people on here and hope for your versions thanks george Quote Link to comment Share on other sites More sharing options...

panoma1 Posted February 1, 2019 Report Share Posted February 1, 2019 No! 2 1/2" (65mm) fibre, 1 to 1 1/16ozs of shot still does the job! Quote Link to comment Share on other sites More sharing options...

Old farrier Posted February 1, 2019 Report Share Posted February 1, 2019 But what about 3 1/2 inch chambers ? 😊 Quote Link to comment Share on other sites More sharing options...
oldypigeonpopper Posted February 1, 2019 Report Share Posted February 1, 2019 hello, back in the days when most i know used spanish side by side having 2/3/4inch chambers we used eley grand prix 65mm no problem, i think a 3 inch chambered shotgun with 70mm cartridges should be the same plastic or fibre, are not the new shotguns designed with a cone breech, where the old shotguns had a slight lip if thats the right word, Quote Link to comment Share on other sites More sharing options...
wymberley Posted February 1, 2019 Report Share Posted February 1, 2019 (edited) As we know, it depends whether or not you want to take back-bored barrels into account. For example, when loading 32g of No 7 which are going to be used in a 3" chambered Browning Maxus.

figgy Posted February 1, 2019 Report Share Posted February 1, 2019 Only way to tell is chronograph guns of the same bore but different chamber lengths with the same carts. Then try carts that match the chamber length. Then you have a true answer. Quote Link to comment Share on other sites More sharing options...
Smokersmith Posted February 1, 2019 Report Share Posted February 1, 2019 (edited) Is there a chrono available for the likes of us that works with fibre wads? Edited February 1, 2019 by Smokersmith Quote Link to comment Share on other sites More sharing options...
Perazzishot Posted February 1, 2019 Report Share Posted February 1, 2019 yes it does, was with Nigel Teague last week, both chamber size and bore make a big difference to fibre. The ideal combination is 2 3/4 chamber for 2 3/4 shell and 18.3 or 18.4 bore. Anything else in his own personal findings can lead to losing up to 25% of the power of the cartridge.

cardigun Posted February 2, 2019 Report Share Posted February 2, 2019 Hi, I posted a photo of a Hull Super Fast Pigeon cartridges' wads a while ago. It showed that they put two fibre wads in their cartridge, which makes it long enough to obturate even in a 3 1/2 " chamber. I have used a lot of them in a 3 1/2 auto Bennelli, and they work fine.

dipper Posted February 2, 2019 Report Share Posted February 2, 2019 Before plastic wads Winchester’s xx had a oversize ie 10 bore card wad over the powder.So it was concaved .I have seen a tool for making these wads .Dont see why it wouldn’t work.

I would think he was referring to bore size..Browning Crown at true bore according to them works best with Fibre...but I anecdoctally think this is all pretty marginal stuff.......I for example have a 2 3/4 chambered browning and a 3 inch browning.....can you tell any difference with a 23/4 black gold in either no is there difference in down range performane/kills...no.......how the heck is 25% performance difference measured??...Chrono at muzzle?....surely the performance should be judged at 40 yards. Alot of top end guns EELL/Heritages etc have 3 inch chambers and I would think 99% of cartridges put through them are 2 3/4 inch.........Would like to see some science etc...but I sure as hell don't feel 'disadvantaged' and have always shot Fibre.

So what's happened as the last time we spoke you suggested I shouldn't waste time at the pattern plate but instead just get out and shoot them. I found this and posted it back in October. Hope you find it of interest: Just nicked this from Guns On Pegs and it's written by Peter Schwerdt of EJ Churchill: "For effective obturation fibre wad shells need to be matched to the length of chamber and shot in barrels that are not over bored. Most modern O/U shotguns sold today are over bored at 18.7 and have 3 inch chambers. The sooner clay shooting authorities ban plastic the sooner they will make guns that will suit the obturation for fibre wad cartridges and improve the cartridge itself to make it even more effective. Until that day plastic will always be better for high bird shooting." Quote Link to comment Share on other sites More sharing options...

This is cheap and simple but it may or may not impact on performance /velocity / patters this as touched on here already , and can be bore chamber sensitive to some extent in some guns. If you want reliable fibre wad ammo that crawls all over plastic wadding even beating it you need to do more to ensure effective gas sealing from the very start of the combustion proses. Inverted card cups over powder felt then harder fibre wad section and undershot cards give little if any disadvantage to the plas wads, to such loads if you wrap and buffer things get even better. Fibre wadding works as well as the attention to detail you give it, as a wad its no better or no worse, and if you add inverted cups with little else you would have good reason to boast they will work in anything and perform better. Try a few on your equiptment with inverted cups this is the way to go with fibre wads and in itself is a good place to start to sort out any fibre problems that might exist.

I see shotgun patterns & results as a 3d thing and 2d pattern plates answer different questions.........true choke/POA etc which are chocolate kettles........yes I have shot pattern cards no I have not done so with same load in the 2 guns mentioned...........I have shot thousands of pigeons/partridge/pheasants and cannot tell any difference between the 2. Nigel Teague (whose 3/8ths I love) knows his stuff and I am in no way trying to undermine his knowledge of barrels/chokes all I am saying is in my experience I cannot tell the difference between 23/4 chamber/3 inch chamber similar guns shooting 2 3/4 length cartridges..and I don't give a rats bottom about plastic wads as I won't use them. Of course I would be interested if someone wants to conduct something a bit more scientific but I do think this could be over analysis paralysis.......

Continental Shooter Posted February 2, 2019 Report Share Posted February 2, 2019 (edited) I have tons of tests an practical examples too and can say that i've always advocate what Nigel Teague said. I did not find the same level of loss he argue, but is there, especially with fiber wada. Practical example: I used to shoot load of 1,10g X 25.5g in a 20 bore Beretta A303 with a 70mm chamber, when I moved to the SX3 with 76mm barrel the load did not perform as usual. After some testing (proof, pattern, chrony, etc.) I moved it to 1.20 X 26g and is back to normal in terms of consistent kills. For how silly that might seem to the untrained eye, even with plastic wad 6mm will allow gases to escape through the gaps between the wad base and chamber walls reducing speed and disrupting patterns. If you consider the fiber wad (which doesn't expand as much as plastic) you can see how the loss in efficiency is made ( lot less speed and even more pattern disruptions).

Sounds exactly how Nigel explained it last week wouldn't be surprised if the information and testing had come directly from Nigel Teague!

mk70 Posted February 3, 2019 Report Share Posted February 3, 2019 Has anyone found a brand of fibre cartridge that preformed better than others. Would a tighter choke help achieve a better pattern in back bored barrels . I’m using a 525 for mainly sporting clays Quote Link to comment Share on other sites More sharing options...

I’m using a 525 for mainly sporting clays Assuming that the cartridge is OK with the more open choke, then it's probably a 'yes'. But if you have a problem to start with then I've found that going right up to X full made no difference whatsoever. I've not had a back-bored barrel for a little while now so have little or no interest. It's always been a case of what CAN happen with these barrels and fibre as opposed to WILL happen. Even so, initially this was largely rejected as a possibility by many but there now appears to be a sea change of opinion. One can't help but wonder if the introduction of the Browning Crown facilitated this change in any way. Quote Link to comment Share on other sites More sharing options...

I tried my nominal bore Benelli with full choke and fiber wad carts, to say I wasn't impressed is an understatement. Poor breaks and no matter how much I tried to center the pattern on a easy clay the breaks were just small bits, not powder puffs you expect. Half choke and same clay ball of dust. Blew its own pattern with tight choke. My over bored guns were much the same, plastic works great. Some fiber carts may work better. Quote Link to comment Share on other sites More sharing options...
TIGHTCHOKE Posted February 3, 2019 Report Share Posted February 3, 2019 Curious, I shot 3/4 and full with various fibre loads at clays this morning and was quite happily getting balls of dust at them. Quote Link to comment Share on other sites More sharing options...
