I have designed a new gun and wrote up some plans. Possibly, someone I know has actually made it, and they say that it works very nicely. You can read the full details at http://www.darksites.com/souls/vampires/feticidal/poisons/scrgun.html Here is a picture of the finished thing: ------------------ |

How come the gun is only accurate under 20 feet? Do you mean 20 yards? |

I meant 20 feet. The person that made this gun has only tested it at 20 feet, it may be acurate past that, but it has not been tested. ------------------ |

It will be only accurate to 20 feet due to the small barrel, 3 1/2" i think, correct me if I'm wrong. Bandit ------------------ |

ok, the gun would only be accurate at close range has nothing to do with barrel lenth. Barrel lenth has very little to do with accuracy. The reason is the barrel needs rifling, used .22 barrles are pretty cheap, cut one to thr desired lenth. |

barrel length has ALOT to do with accuracy. ALOT!! that is why rifles are more accurate at longer ranges than handguns are. granted you can get a handgun to shoot accurate at 100 yards but it is a tough thing to do. the elongated barrel allows for a greater spin and also burn completion in slower buring powders (thus more gas is created and the bullet is pushed faster) one example of the use of longer barrels is in sniping. police and marine snipers do not use a handgun with a scope because it is not as accurate at longer ranges. (they are not as powerful too) ------------------ http://members.xoom.com/Splynncryth |

In practice thats true, although there is a limit as barrel whip is magnified as the barred lets longer.. although it has more to do with the very short sighting plane of handguns (how far the rear and front sight are apart) the further apart the more magnified the error is therefore correctable. but as you said, a handgun will never outshoot a rifle.. |

Longer barrel do not provide greater bullet spin. Rifle bullets are not made travling fast by using slow burning powder, a lot more powder it is. The sighting plane is called "sight radius" Once upon a time, someone shot an 1 inch group 100 yards with a revolver, scoped, and good ammo, it became a legend of handgun shooting history ...that tells ya how difficult it is to shoot handgun accurately. Another reason handguns not being used in tactical shooting is that they don't knock [This message has been edited by HMTD Factory (edited February 29, 2000).] |

I should hope everybody knew what the differences between pistols and rifles are. Anyways, like HMTD said, the barrel is not the only reason why rifles are so powerful and accurate, just look at how much powder is packed behind those things compared to a pistol round. |

well a .44 round has much more powder than a .22 long rifle. the .44 shot out of a hand gun is not as accurate as a .22 LR shot from a rifle (assuming they are both shot from a bench rest with a scope) ------------------ http://members.xoom.com/Splynncryth |

That diameter is twice as large as the rifles... Would you compare an 8 inch artillery piece to a 16 inch naval gun? |

There's 2 ways of looking at that. Either you go for the accuracy of the .22 rifle, or the devestating impact of the .44. But any weapon, a rock or a nuke, will kill you if your head is ground zero. Accuracy is the most important factor because your weapons fire is useless if it doesn't hit its target. So rifle is better. ------------------ |

you know what i just thought. it is not even fare to compare heavier bullets with lighter ones in the first place. if you shot a 100 gran 30-06 out of a rifle it would not even be as accurate as a 60 grain 30-06 shot from a rifle in the fist place (DUH!) so i would like to scratch what i said before about the .44 and .22 (i will not delete it cause people have responded) when a heavier bullet exits the muzzle it tends to rise up and shoot in more of an arc and a lighter bullet will shoot flatter regardless if shot from a pistol or rifle. (i just thought i would clear this up) But the same 60 grain bullet shot from a pistol and a rifle will be more accurate with a rifle due to the longer barrel, bar none ------------------ http://members.xoom.com/Splynncryth [This message has been edited by Ho ju (edited March 01, 2000).] |

first: 100 grain and 60 grain bullets are pretty non existant in .30 cal however i'll play along, the same rifling twist will not stabalise both. nothing to do with velocity. second: your theory is wrong. the heavy is more ballistically efficient therefor loses less energy through the air, therefore past a set distance will begin to travel flatter than the light 60 grain. not that this has anything to do with accuracy. third: heavy bullets certainly wont rise after leaving the muzzel. your thinking of it rising above the line of sight, like all bullets. fourth: so what your saying - the longer barrel gives more velocity therefore more accuracy? ........ wrong. The weight and method of shooting a rifle is far more stable than a handgun will ever be, this combines with the greatly impoved sighting plane and strong actions of rifles. The barrel length is not the significant thing in regards to accuracy. |

i am not even talking about the way a gun actually handles i am talking about the length of the barrel plain and simple. and yes a heavier bullet will rise slightly (not as much as i think you are implying) and no i am not equating velocity with accuracy by any means. a .22 LR will shoot more accurately out of a rifle than a handgun from a bench where they are both stabalized (thus negating the sight plane and the handling all together...) the weights of the bullets were just examples but i think you got my point any how  ------------------ http://members.xoom.com/Splynncryth |

I have seen 110gn .308 load by Winchester. (something 100gn and something .30) Any bullet can have its fly path above the sight line, say a bigbore rifle is adjusted to shoot at 500 yards... Heavier bullets of the same load suffer lower Ballistics and trajectories...hard to say, hard to say... [This message has been edited by HMTD Factory (edited March 02, 2000).] |

I could question many things that have been said, but i wont, as im sure they wouldnt like to try and answer. Ill just say that most things that have been said are far too vague, it certainly isnt a simple yes/no answer, there are many things to consider.

alright i will try and not be vauge on this one when it comes right down to it, there is no two shits about it. a rifle (having the longer barrel) will shoot more accuratley than a pistol shooting the same load... there. if you don't believe me then do some research, all i can say to back this post up is "i knows what i knows and what i knows i knows real well"------------------ http://members.xoom.com/Splynncryth |

shit, i've been gone for a while. Someone up top suggested getting a used .22 barrel and sawing it off, No. because it needs to have threads on the outside in order to screw together, the whole point of the gun. Accuracy is DEFEENTLY factored by barrel length. But in my gun this wouldnt matter beacause this gun design was made with a close range murder shot in mind. It isn't meant to be a champion target rifle. Just a very cheap 'kill someone and throw away' gun. ------------------ |

how about everyone stop talking about barrel length unless they can back it up with a reason.
HMTD: I wasnt going to say anything as ive said it before, but its not bullet weight and velocity that give the trajectory its the ballistic coefficient and velocity. hence the reason .30 cal wont go under 110 grain as the initial velocity advantage quickly sheds off fast due to a poorly streamlined bullet. So although your point is right in many cases its still too vague. Feticidal: At least you brought up the point that its not meant to be pinpoint accurate. Most handguns arnt, simply because human error far outweighs any error in the gun. Say if you bolted a handgun into a clamp and it happend to shoot all its shots into 1" at 100 yards.. give the same weapon to an average cop and he'd be lucky to get the shots within 6 foot of each other, if that. |

Here's a site that explains the physics behind ballistics, http://www.povn.com/~4n6/index.htm . Just for those who are interested in that sort of thing. |
