I shot 1 5/8 oz handloads in 7.5 for Iowa last year. The patterns were similar to the one pictured above, while they are solid they just do not compare to the 9s.
If I was going to a larger size I would go 8 or 8.5, the 9 and 9.5 I have shot have me spoiled I guess.
I was ekeptical of the 9.5 but they performed flawlessly!
