An old timer told me to find the most accurate load..If you're any kind of a hunter you will get close enough to be able to pick your shotl.
Aim for the heart... no matter the range.. don't hold over ...
If he's in range you'll get him, if he's outta range you will under shoot him..
That way you don't leave a wounded critter out there.
I always figgered that was good advice
A round ball will do the job if you do yours.
