I've stayed with the same basic platforms over the years. I have multiples/shoot the same things I have forever. Redundency I know , I just believe in it.
I will always learn, always push and strive. Targets get hit, birds fall, plates hit ground, game dies. I'm not able to shoot right now as I once did, I do dry fire, draw, mount and swing shotguns.
My gunsmith keeps me on my toes with various scenieros.
The day I ever think I've arrived, is the day I'll probably die...I just keep that in mind.
