nabbers Posted December 30, 2011 Report Share Posted December 30, 2011 Anyone ever taken apart a Hull CompX cartridge and weighed the powder checked what primer they use?? I have 275G of the powder and wouldn't mind recreating some. Quote Link to comment Share on other sites More sharing options...

nabbers Posted December 30, 2011 Author Report Share Posted December 30, 2011 Hi Nabbers What powder is that ? Mick. I don't know :o so I dare not use it for anything else due to all the dire warnings on here! Some black powder dude allegedly reloaded compx hulls with BP and I got the powder. I might have to buy a box and do an autopsey But it is a bit like Vectan AS in colour, 2 shades of green and a darker flake, except the flakes are round like they have been punched out like dots?

Mick Shaw Posted December 30, 2011 Report Share Posted December 30, 2011 Hi Nabbers The reason I asked is because I picked up a few hundred 12 gauge Hull comp x 65mm cases a few weeks ago and worked up a sweet 22gram 8 shot load for skeet usung B&P F2x24 powder, CX 2000, Gualandi Vzero25 wad. You could look on the NobelsportItalia web site and see if you recognise the powder. Mick. Quote Link to comment Share on other sites More sharing options...
sitsinhedges Posted December 30, 2011 Report Share Posted December 30, 2011 That unknown powder is worth maybe a tenner, what are your hands and eyes worth Quote Link to comment Share on other sites More sharing options...
nabbers Posted December 30, 2011 Author Report Share Posted December 30, 2011 (edited) That unknown powder is worth maybe a tenner, what are your hands and eyes worth Sobering thought is was £7.50 but to me reloading is pleasurable partly because of the experimentation. I hear a lot of warnings but where do the dangers actually lie? Educate me! THESE ARE MY GUESSES, NOT FACTS... I get the odd duff round where perhaps the powder drop has been low, I check the barrels are clear after every shot/before loading anyway aware of the danger of mud plugs or stuck wads which could cause a burst. Would there be any other consequences of low pressure other than a partial discharge that you could call dangerous? Too much pressure causing the breach to blow off or barrels to burst would be the result of too much powder, wrong primer with large powder load, tight crimp, too much shot to powder combination presumably?? What are the other dangers ? I read of varying pressures due to the temperature the shells or powder is stored at. Example (DON'T DO THIS),Suppose someone used 23.5 grains of any commonly bought(progressive, medium or faster) shotgun powder, any primer, 32g lead any 70mm 12g case, wads to make up the height and normal crimp closure. How dangerous could that be in a modern shotgun? Are these things discussed anywhere? Edited December 30, 2011 by nabbers Quote Link to comment Share on other sites More sharing options...
deershooter Posted December 30, 2011 Report Share Posted December 30, 2011 (edited) Why do people run so scared the fastest powder is 15 grains in 24 gram the average is 18 in 24 gram and 20 in 28 gram start some where between the two and you wont blow yourself up this is on 12 gauge just use a sensible load and a magnum proof gun for testing however if you did not remove the powder check with an unfired one first deershooter Edited December 30, 2011 by deershooter Quote Link to comment Share on other sites More sharing options...

There's no point in making a duff load because you're trying to err on the safe side or risking going over pressure for the sake of a few quids worth of powder. In my opinion obviously. Make a nice flare with it :yp: and then get some proper recipes with powder to suit them Quote Link to comment Share on other sites More sharing options...

deershooter Posted December 30, 2011 Report Share Posted December 30, 2011 Sitsinhedges how can you tell what breach pressure you get with a crono dont these measure speed not pressure ? I have never owned a crono and never used a reloading book just used worked up loads I own a 687 silver pigeon and a 682x trap Been loading for 12 years owned both guns this long and none are showing any sign of wear even after over 60,000 rounds of home loaded cartridges along with about the same in shop brought What tells you your breach pressure do you have a "Helston pressure gun"? this is the only way to be sure.

Deershooter I stated that a chrono wont tell you a breech pressure in my post. What a chrono will do though is tell you whether the cartridge you have loaded is worth firing, whether it has enough speed to do its job effectively, if the recipe you are using doesn't give a speed for that load. Not all recipes do what speeds they claim either. My point is that, esp for someone who is new to reloading shotgun cartridges and still finding their feet, confusing the issue with mystery powders just isn't the right way to go about things because even if the cartridge goes bang and the ejecta clears the barrel you wont have the slightest idea whether it is at all suitable for its purpose. This is just my opinion, and I don't like to waste components any more than the next man, but for the sake of a few quid it is just as well to just make some cartridges from a tested recipe that you know are going to do the job and safely Quote Link to comment Share on other sites More sharing options...

Guest cookoff013 Posted December 31, 2011 Report Share Posted December 31, 2011 http://forums.pigeonwatch.co.uk/forums/index.php?/topic/153866-hull-cartridge-comp-x-21g-75-plaswad/page__p__1310443__fromsearch__1#entry1310443 now guys, manufacturers change components all the time, i`ve bought shells and done a few digests. i only noticed the hull wad change in a few when it was in a clear hull. it is dangerous trying to re-create loads. especially these light loads, they need alot of pressure to burn right. i dont know what the powder is, some industrial powders look the same but have a different nitro content and a different density. sits has a great point, some cartridges dont hit the published speed. i will state again pressure is the key. and as the guy hasnt got a pressure gauge on hand, his powder is next to useless. 200grams isnt much powder. if the guy wanted a decent powder for 21gram loads. he should just buy some lowsonic and go to the proofhouse. £50 a kilo is alot. but when it loads 1500 shells its an economic alternate. just dont be silly. there are new powders coming on the market that we cant buy, or have knowlege of. be sensible especially with 12000psi at your face !

nabbers Posted December 31, 2011 Author Report Share Posted December 31, 2011 I forgot about that other thread! Is 12000PSI a typo Cookoff? do you mean 1200? If a waitress says "hot plate" something makes me touch it. I made up a couple today and fired them from the hip at a pattern board decided my eyes are more important than my ********. Sweet enough, no drama, felt like a compX, louder bang than the subs I've been making, didn't have a compx to compare patterns with. This discussion makes me question reloading full stop, if I'm not safe recreating a factory load then what margin of error do I have reloading anything?

phaedra1106 Posted December 31, 2011 Report Share Posted December 31, 2011 (edited) To answer your original question, in one of my 12g 28gram fibre wad version there's 15.5grains of green and amber flaked powder and .97oz (27.5grams) of shot. I obviously have nothing better to do than take cartridges apart Edited December 31, 2011 by phaedra1106 Quote Link to comment Share on other sites More sharing options...
