I use #3,4, & 6 finish nails. Have done so for years & with good results. In fact probably been using out of the same boxes for 6-7 years I would guess. A pound of #3 finish nails is allot of nails & I am just about to the bottom of them. Once in a while I pull out one that is messed up, but these are pretty consistent .062 and the #4 ones are .067, don't remember what the #6 ones are as don't use them often. I actually like them the #6 best as they are easier to drill & etc., but I prefer the look of a smaller pin on most rifles.
