10mm/.40 bullets?

[I8BAMBI]

I was just looking at the precision delta web site, and noticed that their .40 cal bullets are listed as .400 diameter. All the bullets that I've used have been .401.

Why the smaller dimension?

any reviews on precision delta products and service?

thanks

I've used their 9mm and like them. Not sure on the size, but you should be fine as these are FMJ and not lead.

Usually:
.400 for FMJ
.401 for lead

My understanding is that lead are a little bigger so that they seal up the bore better, to reduce barrel leading. Could be wrong.

I use them for my 10mm. Work great. Leave a round hole in the cardboard.

I have used the Preision Delta 9mm, .40, and .45 all with huge success in both quality and service.
