Spawned by a thread about using Buck-n-Ball in a rifled pistol...
:shake:
Problem with Buckshot pellets behind the ball (the right way to do it for accuracy) is gas blowing thru them, so, much paper on top of powder then buck, then ball. Uh oh -- is ball loose now? Sure. More paper...
Again, that's the right way to do it. Overpowder and overshot cards implied. Now, what size Buckshot pellets!?
Alden says:
You want the largest pellets you can get for efficiency and effectiveness (and range as well as penetration), including pushing the big ball in front of it, but NOT big enough to physically wedge the ball or each-other, create an obstruction (which I became paranoid about when India-made guns first hit the market), and blow up your barrel and maybe you along with it. There are formulas for this I won't go through, however, here are the results for members' benefit re: most common smoothbore calibers this might apply to (don't put pellets in a rifled gun kids).
These are, in order by row, listed caliber, common actual bore size considered, maximum Buckshot diameter advised, standard Buckshot name implied, and the Buckshot's actual diameter per pellet.
.75/11 ga 0.729 0.338 #00 Buck 0.33
.69 cal 0.678 0.315 #1 Buck 0.30
.62/20 ga. 0.615 0.285 #2 Buck 0.27
.58 Cal 0.58 0.269 #3 Buck 0.25
.54/28 ga. 0.54 0.251 #3 Buck 0.25
A safe and effective "square" load of Buckshot can also be determined by using this table with three layers of these pellets (9).
.50 caliber has no Buckshot size that can be used with three pellets efficiently. In this caliber a single layer of five BB's is the biggest and advised pellet size, but luckily maybe the most readily available and in pretty ideal quantities (containers of BB's from a couple of hundred to a few thousand at a time for a BB gun) as well.
.50 Cal 0.5 0.185 BB's 0.177
