Oh where to begin?
A milled receiver should be tight, both open and closed, not flopping around like the action has been shot out (it's a Milled receiver, not stamped parts thrown together). The first trigger on a sporting shotgun should break at 3 1/2 lbs, the second at 3-1/4lbs not 6lbs. The trigger should be crisp, not needing to be pulled 1/4" plus before breaking. You should only have to time your swing, not the delay in the triggers due to creep. The trigger reset length should be in the 1/8" range, not 1/2" plus back travel before reset. Granted that you snap the triggers (pull triggers), but it should be a firm short snap, not a travel threw time and space.
As for fit, the stock is too short, not long. So in regards to having the gun fit, you must of changed the recoil pad. At 6'-1", you butt stock should be around 14 5/8" and not the 14 3/8" that is the factory length. Also, the comb on the shotgun is too low, even on their clay gun. Without a riser, you cannot get the proper check weld, even if you have a long face. Without a tight cheek weld, you would be lucky to break in the teens on the 27 yard line.
As for putting your up against a Browning or Weatherby (read SKB), both are the Yugo's of the shooting world, great old school brand names but lacking serious quality once you pull them apart.
Don't get me wrong, the ruger shotgun works well in the field, as other cheap O/U do, just not as a sporting shotgun that you plan on shooting hundreds of rounds in only a few hours, and needing a POI above the bead (someone needs to clue in Ruger that clay shooters want a gun to shot above the bead, not center of it).
The question is would you put your Ruger up against a Berretta (SO models), Kolar, Keigoff, or a Perazzi for a 500 round practice day, much less a match/shoot were you have over a $1000 in side bets.
P.S. A shooter on our doubles league bought a Ruger, it lasted two shoots and three practices before he retired it and bought a 682(was on a tight budget). After just the second round, the barrel was miraging, and he was flinching from the recoil. Thinking it was him, I tried a round (during the summer). After only half a round, I gave up due to the heat vapors blurring the front bead (trying to see the clay threw the vapors were even worse). As for recoil, it felt like I was shooting ostrich loads, not the 1 1/16 that I shoot in practice.
My suggestion to you is to try and get your hands on a target grade/top dollar O/U and take it for a spin. You will very surprised at the differences.
