Round Ball Hunting with a 10 Gauge

[josie wales]

I purchased a Pedersoli 10 gauge about 15 years ago. I have shot a number of Turkeys, Rabbits in front of Beagles, Geese and Ducks with it. It has removable choke tubes. I want to use it for deer and was wondering what size round ball and patch combination to use. I realize the Perdersoli is not a true 10 gauge but more of an 11 gauge. Does anybody here have a suggestion? I do have two cylinder choke tubes for it.

I have measured the muzzle diameter and purchased the biggest sized ball that will drop in. I don't patch the ball. I use the powder/card/wad/ball/over-card loading. You said you have two cylinder chokes, so whatever the diameter is, get the biggest ball that will drop-fit.

Just for example, I have a fixed choke gun with two different constrictions. I use a .610 in one barrel and a .626 in the other. Those are the biggest one's that will drop in each barrel respectively.

I'm pretty sure, with out checking again that mine is a a ten gauge.
There will be a a metric bore diameter stamped underneath the breech ends of the barrels. Something like 19.3.
What ever it says on your barrels just convert it to decimal inches.
