Yes do not worry i am fully aware of that difference!

I meant that the difference between those bpe round case sizes must have some kind of similarity with the difference between the nitro version in differing case lengths, i.e. larger=more powerful.

However some say they are the same power/speed regardless of case length.......

Better question, of the bpe 577's which is the easiest to get cases for,load and such?

Many thanks

Ben
