Been shooting a Cooper 57 with sk standard plus yesterday which resulted in a 50 yrd. 5 shot 3 group of an avg. .361. Sk match resulted in 3 grp. avg. of .301. Lapua Master L resulted in 3 group avg. of .284. Midas M resulted an 3 group avg. of .054 corrected. Does anyone know if the cci standard velocity will shoot with the sk standard plus. I've heard a lot of good things about it. Ronaka's chart looks promising for the cci standard velocity.
