fishluv,
I live in the southwest where we have a lot of open space and our mountain forests aren't as dense as other parts of the country. We're not required to use shotguns for deer and I don't know anyone who does. When I'm asked for recommendations about shooting out of area my answers fall into two categories. What's your anticipated shooting environment and what do the locals use?
Your 50-yard max target opportunity seems pretty typical for an environment where patches of dense deer woods may be close to people, livestock and structures where longer range rifles are prohibited. Fishluv, your new gun seems well suited to your anticipated hunting environment.
For a smooth bore slug shotgun your main choice is the sights. Old school shooters are accustomed to using their every-day barrel with a front bead for shot and slug, many can place a 50-yard slug in the kill zone with just the bead. Less experienced shotgunners and rifleman may prefer the rifle type sights -- open or optical.
Look at pistol shooters, with open sights, some can keep 'em in the black at 50-yards and others can't hit the cardboard supporting the target. Part of evaluating the shooting environment includes an honest assessment of the shooter's ability. Nobody wants to hear that he's not a good enough shot to go hunting with the big boys. Many of the modern sighting devices are aimed at those not wanting to work on the basics. Why learn sight alignment, and train until you're proficient, when you can get a device that will auto-range and put a glowing dot on your target?
Using sabots seems, in part, to be a way to circumvent the shotgun rules intended to keep shooting at close range for safety reasons. What kind of range and accuracy will sabots deliver?… 100yds?, 150yds? 200yds? -- time to buy a mess of sabots and do some trigger time.
If you're hunting in an environment where it's safe to use sabots (with a trajectory like a .45-70) for long shots, why not try to have the area opened for rifle shooting? When I see large areas (like whole states) that are closed to rifles, I wonder if it's because the game officials are too lazy to make maps showing where safety dictates shotguns. Or, do they think the average hunter or enforcement officer can't read a map? Get real game officials, like rock-n-roll, GPS is here to stay -- it shouldn't be rocket science separating rifle and shotgun areas.
It would be interesting to know how many folks are using expensive sabots in environments where shots seldom exceed 50-yards. And, how many sabots are used for longer (100-yd +) shots in areas that really don't need to prohibit rifles for safety reasons.
