    Huh If it's drilled from a solid steel billet, that means some sort of hammer forging of the basic shape of the barrel is done beforehand, correct? How is the billet actually formed?

    Another question

    How are shotgun barrels shaped such that they taper from the breech so that they can fit the entire shell when chambered? I always thought they were made from tubing or round stock and then simply bored through. Is there something else that goes into it?

    Shotgun Design Question

    Not too similar The benelli inertia system uses a stiff spring attached between the actual bolt body and bolt carrier so that the recoil compresses the spring, camming the bolt body in the barrel extension, and allowing it to release from the barrel. The recoil then carries the entire bolt...

    Shotgun Design Question

    Very Interesting So the recoil issue is primarily one of momentum transfer, not force? You're point about the A-5 is very interesting. Some shotgun instructors teach a recoil-management technique that specifically proscribes pressing the stock firmly into your shoulder. I guess a recoil...

    Shotgun Design Question

    Thanks! Would some sort of delayed blowback (like the KRISS) gun be feasible? The KRISS certainly has an interesting way of managing the action of the bolt. Can the rotating bolt assembly (rotating bolt and barrel ext) be machined simply with a mill, or is a lathe required as well?

    870 guru's I need your wisdom, (Paging Drs. McCracken and Lapin)

    The advantage of shotguns is speed and power. The speed comes from the ease of sighting in using the bead sights or simply the barrel. The power, obviously, comes from the 8-9 30 cal pellets stuffed into one load, or the 1 oz slug. Now, for home defense, you're talking about shooting at most...

    Shotgun Design Question

    Recoil operation usually means that the barrel travels rearward a certain distance with the bolt after firing before the bolt and barrel de-couple. Blowback is where the bolt is simply resting up against the barrel with nothing locking it there. I'm familiar with the A-5. It has a...

    Shotgun Design Question

    I've looked around, and as near as I can tell, 12 ga buckshot loads and slugs build up no more than 15,000 psi, which is less than 9mm. Is this, in fact, the case? If so, why can't simple blowback or delayed blowback be used for semi-auto shotgun actions instead of the rotating-bolt...

    Was thinking Mossberg 500 for HD, handled 870 Express, now I'm not sure...

    My instructor has had a lot of problems getting service from Mossberg. He loves the 870. I own one and wouldn't trade it for any other pump-action. BTW, don't spend a lot of money on bells and whistles for whatever gun you get. Just get a youth stock, a sidesaddle, and a sling, and a...

    War on Terror or WW III?

    They're accomplishing everything they want to demographically. It's a world war when the West actually starts fighting back, i.e. repatriating Muslims to their home countries. Until then, they're ahead. Look at how our 'leaders' pander to CAIR et al. We have a real problem on our hands if...

    Crazed_ss Agreed. But I mean the stripper-clip loading, sealed magazine well type. This would take dremeling to modify.

    California Alert.. SKSs now in danger...

    DSA receivers Guys, I thought DSA sold CA-legal FAL receivers also, i.e. the kind that couldn't be modified. I'm building my FAL, one way or another.

    What if they abandoned California???

    I'm an engineer in SoCal, and I like my firearms. Personally, I think laws are so structured that you're pretty much not even allowed to defend youself here, thus making the deterrent value of private firearms ownership almost nil. On paper, you're allowed to shoot a guy if he's in your house...

    Pepper Spray Question

    Get a streamer, not a fogger. They go farther, they hurt way more, and pack more of a wallop (I can vouch personally). Also, they won't blow back on you when you shoot upwind, or create a cloud for you to accidentally run into (I've seen this happen). The Fox Labs ones are great. To...
