You won't have a problem with 1 1/8 loads.
It only gets bad when you get 1 3/4 or more, particularly the Extended Range.
My 26" VR Patterns really well at 40 yards, the sights are just off. It's easy on the Turkey Barrel, you can adjust them.
My muzzleloader barrel showed up. I'm getting stuff together to try it, I got wads so far (but I want to get some shotcups, I just have the felt type now). I need some FFg Triple Seven too. I have some GOEX Clear Shot around (who remembers that?). Hopefully, I'll have it all figured out by fall Turkey muzzleloader season.
Congrats.
