wtf you talking about? do you know what a sabot is?

I know exactly what a sabot is,but apparently you do not.Let me explain it so you understand.A sabot is any type of object that is between a propelling gas and a projectile(or projectiles)that help form a seal against the barrel to push the projectile or projectiles out.The wad in many birdshot shells is not just a thin plate,it is a cup sabot sleeve that surrounds the shot until the sleeve leaves the barrel-hence it is in definition a sabot.

i think yall need to spend a little time and rounds on a true pattern board 40 yds out with a 30 inch circle see what your gun and load can do then some time on a fitters board to check your poi. if you do all that you may be ready to beat down the zombies when thay come or you may have an idea on how to hit a moving target at 30 yds.sabots are a wad in a way used to hold a single projectial in a larger bore .

I realize that in the shotgun world,the thing that that holds the shot is not referred to as a sabot,that's why in my original post I didn't just say sabot,I said "sleeve sabot style wad" because I couldn't think of it's technical name for it in shotshells-which I now know is an "overwad" because I looked up the name,I assumed people would know what I was talking about.And even later in my post I said that 000 buck is arranged in a certain way without a sleeve,I didn't say sabot.I only answered that I knew what a sabot was because you asked if I even knew what one was,and I do,and technically an overwad is a sabot,it's just not referred to one in the shotgun world.

If you need further proof, read the late Bob Brister's book, "Shotgunning: the Art and the Science." He also disproves other shotgunning myths such as "a .410 will throw a tighter pattern than a 12 gauge given the same choke." The truth is that a .410 will throw a wider pattern than a 12 gauge.

While I agree marketing reps like Mark Twain, " Never let the Truth get in the way of a good story" I am wee bit confused about a 410 having a wider pattern than a 12 ga ?

Someone lent me a book on Trap & Skeet shooting. They had excellent slow speed film on the effect of shot string which is a very old debate that with tech. We can now see. We look at patterns to see how much of a load we can keep in a 30" circle but it doesn't all make it there at the same time. It is constricted by the diameter of the bore and efficiency of the wad to protect payload and clean release. They had their formulas etc. everyone's looking for the best round for their sport.

Full disclosure : Rhino ported choke on my skeet gun

I have a shotgun with a 18.5" barrel on it. How much difference in spread, and range would there be between it, and a shotgun with a 28" barrel.

Just curious.

Thanks
Not really, that`s the job of the barrel chock, barrel length does effect load speed..................
