Well in a post about a week ago I asked which I should get and I finally decided on the 6.5 inch barreled stainless steel version of the Ruger Blackhawk. I was wondering what type of ammo would be best for range time and what should be used on coyotes. Also I need a holster for it, it will get wet often so is a leather holster from rugers website a good choice or should I go with a Nylon holster. I don't want to pay over 100 bucks for the holster unless I have to. Thanks.
