I have two 10 gauges. I don't really shoot them much as my 12 gauges 3-1/2" gun does most of what I need. Your not going to get extra range out of the 10 gauges. The shells are actually a bit slower than the 12 gauge, so you will have to figure out your lead. I feel the 10 puts more pellets on target at once vs. stringing them out. I typically only shoot it for large geese anymore. It thumps them big honkers pretty good.The SP-10 is about a 10lb gun, so packing it around is a bit more of a workout. Going to also swing a bit slower, so you have to accomodate slower swing with slower shells. Might take you a bit longer to find the lead. Some of the dike shooters that are running 10 gauges do do some hot hand loads of various shot. It's a fine line between the skybusting / pass shooting they do. Most of the time it's flock shooting and crossing your finger as I have watched them work for the past 18 years.
One thing to remember is that the old bolt guns and single shots were made for lead only so where you would either have to shoot bismuth or another soft non-toxic load through them.
Don’t get me wrong, on a slow day I’m not going to hold back on pass shooting snows at 40-50 yards. But honestly thinking by purchasing a 10 will extend your distance is probably a stretch. My opinion is spend the money on decoys...etc"
I'm not sure where you're getting your information that a three and a half 12 gauge is faster than a three and a half 10 gauge 1600 feet per second is 1600 feet per second. And that's what I shoot out of my 10 gauge and unless you're loading your 3 1/2 inch 12 gauge by hand I don't believe they make them that go that fast. And actually a 3 1/2 inch 12 gauge has more recoil to it because it has more constriction coming out the end of the barrel then a 3 1/2 inch 10 gauge with the same amount of shot. So my vote would still be for the 10 gauge. And yes I do load all of my 10 gauge ammo. And I have never shot on the West side before but I do understand there's quite a few sky Busters or I guess very optimistic people that shoot over there. I don't believe that you get any more power out of one gun versus the other but it's actually the amount of shot and the pattern that you get while shooting. I've heard all the folks say how they shoot 70 or 80 or 90 yards but realistically a long shot should not be more than 40 or 50 yards Max.
