A lot of my shooting pals are going for 20 bore shotguns they say that they are a lot lighter to carry when you'r out rough shooting all day and because they are lighter you can still swing through your quary when you are tired at the end of a day walking about, is this the case or is it because me and pals are getting on a bit. I still use s/s 12 bore but must admit when i borrowed a 20 bore for an hours walkabout in the summer i did like it and i had a few kleen kills with it. So do i get myself a 20 bore or not .Any comments an 12 20 or even 16 bores for rough shooting.
