Re: Sellier & Bellot LR primers.....
Usually people ask before ordering...LOL Just messing with you - I understand you buy what you can find these days. I haven't used them I'd imagine they'll work well. Just to be safe like changing any other component in the reloading equation, start your powder charges a bit lower and work up and you should be fine.
I've shot plenty of their ammo without issues, in handgun and shotgun. I doubt you'll have any issues with their primers.
