I can say that it does cycle the SA rounds just fine. I stripped the bolt and cleaned it and now that is a little clunky. I used a little Rem Oil, I know,I know, on the bolt while it was apart. Can't find 90 gr accubond bullets anywhere. Nosler doesn't even have them currently. I like the way those expand at the velocities I will be shooting. Picked up some ballistic tips in the meantime and will reload those into some of the lubalox nickel cases from some Winchesters I bought at the gun show today. Apparently everyone bought .243 yesterday and no one had any today.
