At what distance would I use to determine POI of new trap gun on paper? It will have an adjustable comb and graco adjustable pad? Thanks for the advice in advance.
I don't agree. If I have a new gun, new stock, new barrel or have modified anything at all, I go to the pattern board and see if my gun is shooting perfect vertically and somewhere around 70/30-80/20 on my trap gun and 50/50-55/45 on my skeet. I then shoot rounds and fine tune until I like the way the targets break with my timing. I don't worry about the final adjustments being 70/30, 80/20, or 90/10 and I don't care if I see rib or no rib. I only care about the timing and break. (Just my way).Your point of impact on paper is only important on a new gun if you are comparing it to a gun you have been successful with.Shoot the gun at targets first,otherwise you are going to force yourself to learn how to shoot a gun based on paper.
That is definitely true but if you are using proper technique at a moving target with a gun that shoots where you are looking you will smoke the target. POI on paper isn’t the end all by any means but in my opinion is a good starting point in the tuning process. You won’t break targets if the gun isn’t shooting where you are looking. I will agree it shouldn’t be bench rested but mounted as you would when shooting trap and shot off hand at close distance such as 13 yards. This should be done multiple times so you can see trends in how it shoots not what might be caused by a flinch in one shot. Then as others have suggested shoot straight aways until you are smoking them.I'm confused. Rollin seemed to give POA, not POI. Rollins method may get you in the ball park, but doing as the other guys suggested will show you what you want to know. Shooting a moving target with a moving gun is different that bench resting and aiming it.
Neil Winston spelled it all out just like Rollin .Rollin's method is right on.. That will give you and accurate POI. But the next step is to shoot at targets using the sight picture that you prefer and adjust that POT until you can smoke all targets . Some one suggested using post three and and setting straight away targets , not a bad idea.
