I think that if you have any Lill Gun laying around, you may want to try 14 to 15 grains of it in your Furball that that bullet and Rem 7.5 primers to light it off and you should be well pleased. I have had a Furball for a number of years now, and just fall in love with the little gun every time that I take it out. Ground squirrels, praire dogs, coyote, and badger all have fallen to this nifty little rifle.
I just love it.
