Hard times call for drastic measures - seems like the fewer the ducks folks are killin' the mo money they spend an anything they think will help'em kill a duck........@ 70 yds.
When conditions warrant, I keep a few Supremes in the bag. I only use Hevi-shot for cripples on the water. No sense in extending the effective killing range beyond the particular shooters' capabilities. I don't know about most folks, but it seems my effective killing range varies from day-to-day. Some days I shoot well-enough to try 50 yd shots (IM/F w/3dr 1-1/8oz lead shot on doves)......others, I better keep it within 25 and open-up a bit (IC/LM w/1550 1-1/8oz steel).
Obviously shells, chokes, loads, range, barrel length, target acquisition and shooting style vary widely among shooters. Case in point, I'm not likely to take 50yd shots at a crossing honker going left to right while sitting on my butt in a ground blind - straight-up, maybe - but it'd have to be a straight-on incomer or slightly quartering incoming to the left side.
As most folks know - If you can't put the shot on the target - shell selection is moot. Shoot some 50yd sporting clays targets before the season with steel shot to get an idea what your
realistic capabilities are. I think the assumption a lot of folks make is that the problem in 'missing' lies with equipment. It could be the lack of one's ability to adapt to the equipment selected for a particular game. That's only determined after shooting skills are honed to the point where you consistently hit 96% of what you shoot at. Otherwise, you're wasting powder - skybusting.
Just last year, I was invited on a dove hunt and took my duck gun - couldn't hit squat because I was banking on shots inside 30 yds. That gun is too light to swing smoothly in those circumstances. The next weekend we went to the same field. I took the 30" IM/F 8-1/2lb trap gun and 'Wowed' myself......talk about picking-up your confidence level from the previous outing.
Shoot a round of trap from the 16 yd line using Mod. choke and 1-1/8oz loads - Get to where you can hit about 20 out of 25. Then step-back, go to Full choke and shoot rounds from 20, 24, and 27. If your technique is not good on the 16 yd line, it won't be any better on the 24. You'll be completely clueless of where you're shooting (other than 'down-range'), by the time you get to the 27.
