you peopel must be in fifth grade and being immature out of all forums ive been to you guys have been making the most childish comments and not adressing the issue pikcing on people.

Officer of Engineers

LMAO!!!!

Your terrible grammar and horrendous spelling and you call us in the 5th grade?

Just nitpicking.... I know what that bloody doll is about.

Rifled gun can accomodate a greater variety of shells. Shells like HE-Frag and beehive are very useful against the infantry. M1A1 for the better part of the past three decades got only HEAT and APFSDS.

That said, it's not impossible to get those shells for smooth bores--the Americans just got a smooth bore beehive round, and the Ruskies had 125mm HE-Frag for years.

Your grammar sucks to the point as to make your posts unintelligible.

Please seek professional education assistance.

Not a beehive but a canister. They are close but not the same thing.

Anon

Flecthette vs grapeshot, yes?

tankervet

Yeah thats correct. I have no experience with the beehive but from what I have seen of the canister its very impressive.

Also there is no reason why a smoothbore tank could not fire a antipersonel round such as a beehive or whatever. Obviously because we have it now but even before if you think about it. Most antipersonel rounds dont require stabilization in air and thats the only disadvantage of smoothbore is that rounds must be fin stabilized.

There are several ways to set the fletching on arrows.. the are set in various offsets, that are measured in degrees, 8, 10 and so on, not all arrows have a fletching offset, some fletchings are set to zero, NO SPIN on the arrow, the aerodynamic drag of the fletchings is what keeps a arrow straight during flight, some people shoot better without spin other shoot better with it.. spin has little to do arrow being accurate..

Smooth bore Vs. Rifled, Smooth Bore allows for higher velocities, adding to range and penetration at greater distances due to greater kinetic energy down range (weight X velocity = Kinetic Energy), adding to the ability to punch though amour at greater distances.. the loss of accuracy is extremely minimal, to the point of not being a consideration when the object being fired is provided with the proper aerodynamics to maintain a constant drag coefficient in flight to maintain its stability..

Spinning has nothing to due with keeping the nose pointing in the right direction, it has to due with accuracy.. proof of this being, if you take a cross section of a bullet, and find the center of mass, the center of mass is usually well behind the actual measured center for most all bullets and shells (arty). Yet, when a bullet strikes something like soft to moderate tissue almost all bullets turn heavy end first, meaning, when a bullet strikes, on average, most will go anywhere from 4" to 19" (depending on caliber, type of bullet, and energy of bullet and medium bullet is moving though) before they turn end for end and continue, when they exit a body it is more often tail first (basic physics, heavy objects pull light objects unless acted upon by other forces).

Well, I've done a lot of pit time and pasted enough targets to know when a hobbyist has sized down his bullets too small for the rifling of his barrel. I'm sure you know what the term "keyhole" means.

Actually, ballistics are very complex. Whether smooth bore or rifled, if the projectile is any shape other than spherical it has to be designed to keep the center of (air) pressure forward with the center of gravity aft. Accuracy of that theorum was discovered accidentally when certain hollow point bullets proved to be more accurate than standard FMJ.

If you have any National Match rounds for 7.62 NATO (M-1A & M-14 rifles) or .30-06 (M-1 Garands & 03-A3 Springfields) lying around, take a close look at the nose of the bullet. It has a very small hole in the tip. This is to build up forward air pressure.

Oh! As for arrow fletching. Almost all arrows fletched for speed, accuracy and/or penetration are canted for spin. The fletching is usually relatively small also, particularly for high speed arrows. But fletching for distance shooting is rather large and usually not canted and are called "Flight" arrows.

A friend of mine (Bill) used to participate in distance shooting. He cheated though. Weight lifting was a hobby of his. Plus he was a Structural Steel worker with me (adding versatility to his weight trained muscles). Plus the bow was custom built by one of our fellow workers (a welder at that) and to shoot it Bill had to lie on his back and use both hands AND both feet to draw it.

Not too many archery ranges around that are long enough for that kind of contest.
