Let's just make this real clear-
SS109 projectiles will NOT consistently hit a sub 2 MOA target. The bullets mechanically can't do it. Occasionally put three "sub MOA"? Sure..... And then the next is 3+ MOA out.
They are blasting bullets- nothing more, nothing less.
I know a couple of high master competitors that could buy them cheap years back and always swore they were ok. The same folks said what I always said about 55s.. junk..
Just saying.. me I just paid for sierra 60 flat base HPS for practice.... they were not that high at the time.
