All of 'em!
Seriously, I only have 1 handgun, 1 shotgun, 1 "deer" rifle and 1 rimfire.
-G21SF and Springfield (.22) go every time. Glock I clean after every trip or every other. The .22 has already been cleaned this year.
-870 only if I have buddies with me and we are planning on killing a bunch of clays (or at least giving them a good scaring)
-Marlin (30-30) makes a rare appearance as I don't think of going thru a box of that to be "fun"....and if I hunt, I used my dad's .270 (which is even less "fun" to practice with, but I do try to keep accurate)
Oh...my "range" is my parents' 40 acres, so I don't have to worry about what I can shoot where and constantly watch up and down the line to see how many muzzles are pointing my way...way more relaxing shooting
