Hi, so I haven't been grouse hunting for almost 20 years. I used to have a single 12g but found that too much for upland hunt. Would like a 410 but ammo, hard to get? Is it the pandemic or just not vailable? So I have been trying to get a 20g pump action with a improved choke. Trying to get a used one. Newer shotguns feel bad. Anyone have any ideas on the best grouse shotgun set up? Should I not give up on the 410? Thanks.
