i use a .715" from a Rapine mould in my .72 Kodiak with .015" patch. before i funneled the crown like Daryl suggested i had to use a .010" patch to load it. i have measured three different .72 Kodiak's and the bore was .724"-.725" on all of them. groove was .734"-.735". i made a short starter on the lathe with a .650" diameter as most on the market are for .50- .54 cal guns. this and Daryl's crown makes a tremendous difference in ease of loading.
