Blade Runner Blaster, Making a Shooter

[joberg]

You might be right simiouno about using a small loaded blank...but still with a half load, those gases have to go somewhere.
There's a behind-the-scene pic of Harrison firing the gun, and man! Still a lot of crap coming out of that prop

Side gas blast is always a consideration, but I still like it better than CGI ..Did anybody watch myth busters on this subject ? They substituted sausages for fingers getting too near the gap..blew them to bits .. I think Adams blaster is great, but as he built it from real gun parts I wonder why he didn't make it live fire , even just for the fun of blanks..I guess a blank gun could be built in to one that's vents up , perhaps through a vent in the bolt slot ..

A Nagant camming gas-seal revolver would probably be ideal, the only problem I might see with it is the ammo - Prvi Partisan makes it, but they mix Boxer and Berdan primers so there'd be issues of REALLY working to keep it clean, not knowing what you're getting. That's not a difficult thing to do, but it is something to keep consideration of. You'd run into the same problem with other surplus ammo as well, but the PP rounds seem to be at a fairly nice price. I can't imagine the Nagant would be all that bad in recoil, so it could turn out to be a fun shooter. Could probably load your own with a slightly slower burning powder so you get bigger muzzle flash as well, if you went that route.

Thinking about it, the Nagant might also be a good choice for the BSG "revolver" - that thing's practically a solid shell all the way around, so having a gas-seal on the gun would be just as nice. Looking at prices...well, seems the market has gone up quite a lot the last few years; bottom end is around 300 and mostly in the 6-700 range for a good condition gun.

Will the Nagant's (seemingly) long and high hammer fit in the Blaster's geometry, though, with that undercut and the back end of the Steyr receiver?

As I said it would make the gun a little different..in blanks you can get a huge flash with flash powder blanks, or the old trick of having your wad soaked in meths spirit..and left to dry before making the load up..it's an old STEMBRIDGE trick ..they may have had them in the PREDATOR mini gun under the crimp I think there was also a gas & oxygen feed that was ignited by the muzzle flash .. in blanks they would have to be made like 5 in 1s with an over long case bullet shaped at the end for the NAGANT ..
