BH,
Hey, that's what makes for good horse races! I just see the market is quite limited today. Finding various loads, shot sizes and barrels are definitely limited when it comes to 20's. My Ithaca 12 gauge m37 kicks like a mule w/ deerslugs, but when you're drawing down on a nice trophy buck I don't sweat it. Now, this young man has shown an interest in pheasent, squirrel, duck and perhaps geese (but so far I didn't hear anything about deer??). Yes, I think a 20 will do a good job....but the 12 will always do it a bit better. Just my 2 cents!
