What I've actually got:
22LR: some kinda russian army training rifle (bolt action) from Marstar for a hundred bucks.
270 winchester: Remington 700DBL, bought second hand, never much liked the scope so replaced it with a Bushnell trophy 3-9x40, still not happy with the groups, tried free-floating barrel, will test this weekend.
12-gauge: Mossberg Maverick 88, the older one, no vent rib, no removable chokes, 3" chamber.
What I'd get if I won the lotto:
22LR: haven't really thought much about this one.
6.5x55 Swedish: Tikka synthetic/stainless
12-gauge: whichever of the benelli Nova, Remington 870, or mossberg ATS shoulders best and has the safety placed so it's easy to flip it off as I mount the gun. Basically, a pump with chokes and a 3-1/2" chamber.
