Yes it is. Bought a 562 as well and it just did not do what i wanted. I averaged over 300 in 10" circle with my gun #9 TSS handloads. 1 5/8 oz @40 yards
It shoots decent in my two sp 10's! Better in one than the other. Shot winchester supremes. Did not like federal with flitestopper type wads or what ever they call them at all. I never did a pellet count on these that I remember and haven't carried heavy sucker in 6-7 years....
