I'm a Mossberg owner again after many years. Just purchased a 410 Shockwave for the sole purpose of shooting poisonous snakes (if necessary) while on my sister's property. I chose the 410 due to my joint issues from arthritis, osteo, degenerative disc disease (you name it). I can certainly shoot a 12 or 20 gauge but it plays havoc on my poor old joints. And I think a 410 will certainly blast a snake. I should have my Shockwave in a couple of weeks. I've read up on ammo for snakes and recommendations range from #9 (or #12 if it could be found) all the way to #4 and #6. The type of poisonous snakes they have are rattlesnakes, copperheads, coral snakes and cottonmouth. If anyone with a Shockwave 410 uses it for killing snakes, what is the best ammo to purchase? A variety of #9, #4 and #6 or all #8 or what? I'm afraid I'm a bit confused. I would be shooting the snake certainly within 5-7 yards in all probability. Any brands of 410 ga to stay away from? Thanks for any suggestions you might have.
