RE: Recoil
During the test pattering of heavy turkey loads it is very possible to develop a “Flinch.” In repeated shots the “Flinch” can become second nature and the automatic reaction can happen with or without the shooter be totally conscious of their reaction to an anticipated shot.
One can use a “Snap Cap” to check their reaction and I bet many shooters would be amazed they are jumping from the recoil which can “Yes” effect the point of impact especially with very tight shooting chokes at short and/or long range.
Anyone who was done any amount of shooting has probably noticed the “Flinch” reaction. If one says I might “Flinch” on the range, but I will not “Flinch” on the turkey, they are probably lying to them selfs...once developed it becomes second nature and can be cured but only by a concentrated effort.
If you are spending big $$ and time patterning your shotgun, choke and loads to get your gun's best performance, you might want to verify you also have yourself “Flinch” free so you can perform as well as your gun.
Some people discover instantly they were just not “Put together” to handle the pounding of heavy recoil and for some others it takes time for them to realize they will shoot better and take their share of game without the punishment of heavy recoil and big $$.
If you can truly handle it, hey go for it, but be honest with yourself and choose the load which you feel comfortable shooting and which will provide a good pattern at a reasonable distance. Extra heavy loads are not a requirement to kill turkeys.....
