Pattern the gun if it's centered no worries. I have an SP-10 that for no reason that I can determine throws turkey loads a little left. It was a beaded gun(no sights) I put Wilson sights on it. To be honest I have no idea if they still make em, the gun was bought the first year Remington made em.
I'm not a scope guy, and def not a peep guy w turks. Darn things come bopping in n it seems like a heck of a thing to get their neck in the peep. I find open sights easier/faster as you can see sights and what's right next to it if the turkey does do that head bob thing.
Check it first though
