What is the difference between copper plated buckshot vs non copper plated buckshot? Thanks |
|
one has copper plating. i think i read somewhere that the copper plating allows the shot to "slide" through chokes better and gives tighter patterns. or maybe makes the surface harder for less deformation. or maybe to camoflage the shot cloud so the deer don't see it coming. ok i admit it. i have no idea. |
Buffering also reduces pellet deformation, its kinda like tiny packing peanuts mixed in with the shot. However if you decide to reload buffered shells you cant use ordinary data, you must find data that accounts for the buffer. You might also hear of "duplex" loads in which 2 different sizes of shot are mixed within the same shell. |

there is a lot of hype about shot-pellets,some guys even get better groups with recovered shot than new. I know a bad analogy but the first golf balls were round(perfectly so)and they didn't travel well. They then dimpled the balls and they were faster,and traveled further. Some fell the same about shot,the more imperfections the better. Bob

Plating: The shot is plated with copper/utopium/whatever. This allows the shot to retain its shape better as it transits the barrel. The forcing cone restricts the shot as it leaves the shell and moves down the bore. The plating helps to ease this process and keeps the shot more spherical as opposed to being forced into an oblong and theoretically less efficient shape. As a result, the shot is held together better as a mass and keeps a tighter pattern. The plating also keeps the shot from being deformed upon striking the target, and helps to give a little more surface hardness to the individual shot. That's why plated shot tends to yield more penetration, especially in things like drywall. Buffering: Similar thing, it helps to buffer the shot load as it moves through the forcing cone/choke and helps to keep the individual balls from slapping together. Wow, that was an odd sentence. Anyway, it also can help to keep the pattern tighter due to less deformation of the shot. So, while buffered plated shot might give you better patterning and increased penetration, that has to be weighed against maybe a desire to have a more open pattern, or a concern for too much penetration. At least, that's my memory of these things from back when I was working on a departmental decision about if patrol carbines should be used and what the capabilities of the shotgun versus the carbine were. |
Not until today have I ever seen the soft porno side of shotgunning. |

IIRC Cu plated Fe shot was also sold during the early days of NoTox laws as being "easier" on guns that might be questionable as far as Fe shot... At least I could swear there was an ad from one of the ammomakers that claimed that. Or, I could be old and forgetful.

There's nickle-plated shot, copper-plated shot and hardened shot [called 'magnum shot'] - usually hardened with antimony and is harder than copper and nickle-plated buckshot. Hardened shot aids in patterns, penetration and pellet deformation. I prefer antimony-hardened shot like Winchester uses in their Low Recoil buck loads over copper and nickle plating |
