Just trying out a buddies 12g Silver Reserve to see if I like it. He's had it for some time, and says he never uses it... only put about 20 rnds thru it. I plan on using it for clays.. trap and skeet, mostly skeet. Anything I should think about doing before I shoot it? I did take it to my local range today and put about 10-12 rnds thru it and it seems to be working fine. Cleaning the barrel is not an issue, but how does one get to the trigger mechanism to lube it? I'm guessing that there is a bolt of some kind thru the stock, accessible by removing the butt plate? And, in reading the posts here, trulock chokes are the ones to use?
