Hi,
So when you all order/buy bullets (assuming that you don't cast your own and they are all perfect) what would you expect for tolerances on the bullet diameter? If they claim .401, what would be acceptable if you measured them?
In my case, I have some bullets I ordered and received for my 40 S&W that measure .4015 on my high end Harbor Freight calipers. The plunk test is real tight in my XD40 and depending on the brass, many don't pass. It's really close on most of them, as I have to push them in just a little.
So, I colored a particularly bad round with a sharpie, pushed in the round a few times, and found that the high spot on the brass is at the base of the inserted bullet. Back to the calipers I go, and I see that the base of the bullet seems to have the largest diameter in the few that I measured. These are coated bullets, so I wonder if the coating is just a little thicker at the base. I also wonder if they were never sized after coating.
Anyway, is .4015 too big in your opinion? I'll take humble opinions and all other kinds as well
Thanks!
