Seems to have been declined already by a third party. The shortcut makes sense to me - short for Ain't Broke Don't Fix. Modest Genius talk 13:19, 9 March 2015 (UTC)

Disambiguation link notification for April 21[edit]

Hi. Thank you for your recent edits. Wikipedia appreciates your help. We noticed though that when you edited French Revolutionary Wars, you added a link pointing to the disambiguation page Treaty of Basel (check to confirm | fix with Dab solver). Such links are almost always unintended, since a disambiguation page is merely a list of "Did you mean..." article titles. Read the FAQ • Join us at the DPL WikiProject.

Why early Explosives Company propellants were suitable for shotguns but not rifles[edit]

I can offer an educated guess in response to your question on the smokeless powder article on the basis of professional knowledge; but in the absence of published test data on the propellent of interest, this would be inappropriate for inclusion within the article. The reaction rate of gelatinized nitrocellulose increases with increasing pressure. This is thought to result from the insulating properties of the foam zone at the reaction front as explained in the article on Piobert's law. Energy released in the flame zone must be transferred as heat through the insulating foam of melted propellant to sustain decomposition of the solid propellent. At low pressures, gas volumes approximated by the ideal gas law will be relatively large in comparison the molten liquid volume, and the foam will be an effective insulator. Smaller gas volumes at higher pressures will allow more efficient heat transfer, and accelerate the rate of reaction.

Pressure will tend to drop as the volume of the reaction chamber increases when the projectile moves down the gun barrel; but the increasing pressure must first overcome static friction of the projectile within its cartridge. The transition from static friction to lower kinetic friction may have been assumed to be faster in a smooth shotgun barrel than within a rifle barrel which must also engrave the rifling into the projectile and overcome rotational inertia. The reaction rate of the early EC powder might have been too fast within the sustained higher reaction chamber pressure of a rifle barrel; and the increased reaction rate might have generated pressures even higher than the firearm could withstand.

Interesting, thanks. So a short way of putting that would be 'because the lack of rifling in a shotgun allows a smoother expansion of the gas'? Modest Genius talk 10:20, 27 August 2015 (UTC)
  • That explanation might be satisfactory for individuals understanding the relationship between pressure and reaction rate of nitrocellulose propellents; although I might suggest substituting something like "reduces resistance to" in place of "allows a smoother".
As a matter of historical interest, the paradox gun was designed to utilize the faster burning propellents of its era by delaying the resistance of rifling until expanded reaction chamber volume had dropped peak pressure. As might be expected from its inadequate reference citations, the Wikipedia article fails to mention both the accelerating twist of paradox rifling (initial rate of rotation less than rate of rotation at the muzzle), and the ineffective shot dispersion patterns created by a rifled barrel. The initial paradox guns were not intended for use as shotguns. They were 4 gauge or 8 gauge guns designed to throw very heavy projectiles (sometimes including an exploding charge of mercury fulminate) against large and dangerous "big game" animals before modern rifles were available. The 4 gauge guns created punishing recoil firing a 4-ounce (110 g) projectile. It was said, only partially in jest, that after the hunter fired at the beast, the first to recover their footing finished off the other. Thewellman (talk) 16:54, 27 August 2015 (UTC)
