There is an old wives tale about not "aiming" a shotgun. I mounted an EoTech on one of my competition guns and it really helped new and poor shooters. I only tried it for about 8 weeks and reverted back to bead sights when the large state/regional competitions started back up as I was a bit better with the "old way". I think if I had stuck with the EoTech I may have eventually been as good...maybe better. (I was averaging 98+ at the time)
One of the better competitive shotgun shooters I know has his lenses ground so his front bead is in perfect focus...he aims. Every competition shotgun used in Trap shooting has two beads. I believe most use a mix of pointing and aiming...I mostly aim.
New shooters that "aim" seem to stop the gun and shoot behind the bird...that may be why "pointing" yielded better results.
BTW, I was pathetic with the shotgun. Used to shoot scores of 15-17 in my twenties and got frustrated with it. In my early 50's I got the bug and it took a lot of rounds to get decent. 15-20k rounds a year and 10 years later fired my first 200x200 and took second place in the shoot off for the state championship. Been away from it for the last 5 years and only shoot for fun now. Had a serve injury that forced me to quit one year, and never went back. It is one of the most expensive sports to participate in. Lots of good folks and a lot of older ones...I fear coronavirus may affect the sport big time. Many shoots are being cancelled but no reports yet of deaths.
