RE: Do we need new rounds?
I agree with the 10gauge comment......
I really wanted to get a 10gauge just because I had a 12, 20, 28, 410 already,
then I looked at the loadings and they were either the same as 12gauges or even worse/less!
I also kinda want a 16, but knowing they only load in 2 3/4" .....so to date I have neither.
