Hello, I was looking for "dumb question" section of the forum but I couldn't find it, so its going here. If there is a more appropriate place please let me know.
I am somewhat confused as to what a bore riding Boolit is. I get that there is a bore and groove diameter, however isn't the basic theory for all Boolits to fill the entire bore, otherwise you get gas cutting? Wouldn't something skinnier cause problems? Thanks for your help.
