Wingmann Posted June 30, 2013 Report Share Posted June 30, 2013 Wouldn't the last BB block the gas inlet? Link to post Share on other sites
amateurstuntman Posted July 16, 2013 Report Share Posted July 16, 2013 Remember in the China Lake thread I said I had an idea for an airsoft gun that was revolutionary? It is a shotgun idea. We really should talk. Link to post Share on other sites
ED-SKaR Posted July 17, 2013 Report Share Posted July 17, 2013 I have a mechanism design in my skull for a shotgun that suits me perfectly, but I've no skill, tools or materials to even think about actually building it . Link to post Share on other sites

Snoop-Uk Posted July 17, 2013 Report Share Posted July 17, 2013 What about a trident setup for barrel/feed with a pressure break valve or where the load splits across all 3 should prevent over pressure Link to post Share on other sites
Snoop-Uk Posted July 17, 2013 Report Share Posted July 17, 2013 Just thought for the break action ball valve like idea for break thinking it fills the expansion chamber in the front of the stock etc? Or back of it either or Link to post Share on other sites
renegadecow Posted July 18, 2013 Author Report Share Posted July 18, 2013 trident setup Can't quite say I understood that. You mean the third to be an overpressure valve? Link to post Share on other sites
Avenger96 Posted July 21, 2013 Report Share Posted July 21, 2013 This is definitely a neat project. There are a few things I think would save some hassle though. One being hop-up. Hot necessary is it? I can only picture it making the spread funky and making you need more power. Also, again thinking of spread, would an 8MM barrel with 6MM BBs not add a better pattern, givin the rounds more "wiggle room"? This would require more power though, with plenty of air escaping.

renegadecow Posted July 22, 2013 Author Report Share Posted July 22, 2013 I figured the hop is more on keeping the bbs from rolling out because when you load a shell it dumps all its contents into the barrel. From my experience in chucking 6mm bbs in an 8mm barrel, it seems to work ok. Power is greatly reduced though so maybe a 6mm barrel at first then opens up to 8mm. Personally, just mixing bb weights increases spread well enough even on 5-shot Mossbergs. Link to post Share on other sites
shmook Posted July 22, 2013 Report Share Posted July 22, 2013 Yep, if you want spread, mix weights of BB! When I had my Clarence lei M1100, I used to hand load shells with weights from. 12 up to .4g. Can't remember the exact figures I got, but with 10 bbs, I want getting spreads of around 10 feet at 20 metres I think, with a .4 'slug' in the middle of the shell rocketing out to 30 ish metres... Different system, I know, but principles should be the same. Mine ran at 400 fps with a .2g bb Link to post Share on other sites
Snoop-Uk Posted August 4, 2013 Report Share Posted August 4, 2013 Just to expand on trident was meaning 3 load barrels but the reservoir is a single one so the 3 barrels are fed from 1 single nozzle Link to post Share on other sites
