Any experienced deer hunter will tell you that a 410 using slugs is not an adequate deer caliber. You can kill deer with a 22 or a load of bird shot if you are close enough but no one kids themselves that these guns/loads are adquate . The game we hunt deserves better and adequate deer calibers start at the energy level and ammo types provided by the 243 Win and then with the largest bullets. We should have consideration for the game we persue and not what will work when everything goes right but when things go wrong, as they sometimes will, and do the best we can to achieve a clean and humane kill. You will sleep a lot better if you get a decent tool for the job at hand. Not just my opinion but the majority of hunters who engage in our marvelous sport and want our kids and grandkids to have the oppertunity to enjoy it feel the same.
