I then loaded five Remington 2 and 3/4 Buckshot, 3 BK, 20 pellet shells that I assume would be good for home defense. They all fired as expected. By this time I was running out of time and had already blown some pretty good sized holes in the cardboard backstop. So I fired 13 shells total and had one failure to load. I cleaned the gun prior to use being careful not to oil anything as the owners manual is specific about not over lubing. Just wiped down with a WD40 like lube to prevent rust. So I like the shotgun, but am concerned about it's performance thus far since the intention was for home security. I'll shoot it some more the next time out to the range. Any thoughts about the failure? Thanks.
