Interesting.

I ended up with a bunch of .2625", 156gr. Blue nose (large lead round nose) I thought they would be .264", but are under size.

One of these days, I will try them in my 6.5x55 Swede, but with it's .266" groove diameter, I don't expect much for accuracy - we will see. I may try them in Carol's .260 as well, as it has a standard .264" groove diameter.
