ok so i exagerated a little looking for 22/250 preformance. But sub 2 in groups at 100 yds is not to much to ask is it?
Sorry about any misunderstanding. Computer messages have no tone or inflection and can be offensive to people even though no offense was intended.
My point is that 2 MOA off the bench at 100 yards is possible with a scoped and properly zeroed rifled shotgun barrel. 3" magnums are not required for whitetail deer in my opinion. Most 2-3/4" sabots are well over 1400 FPS. The lighter, solid copper versions approach 2000 FSP. All I'm saying is try the 2-3/4" rounds. Lightfield Hybrids (2-3/4" at 1400+ FPS) are another round I've used in my old Mossberg 695. Again, same hole performance at 50 yards and yes, sub-2 MOA at 100 yards with a Leupold fixed 4X shotgun scope. I have yet to scope my Encore but will let you know the results with the Federal Premiums at 100 yards and beyond when I do later this year.
Seroiusly, a shotgun slug past 150-170 yards, in optimal conditions, against game, is pushing it to the extreme. Wounding is more of an option than a clean kill. FWIW
