Thank you all (from TFL, THR & GT) that have helped me in my shotgun selection process. Was that a hard decision or what? The Rem. 870 Marine is on the way! Now that the hardware issue is settled, I need help in the most crucial part of shotgunning: software. I will like to start as a baby that I am (in shotgunning that is). Crawl first then on and on. My primary objective is home defense with hunting a distant second. What will be the best shells to start learning with, what do I need to know about this gun and its usage that are not usually stated in the manuals? From my experience with handgunning, I know that practice, practice and some more practice is the golden rule. How about dry practicing with shotgun? What do you sages say.
