I shot Nosler 77s for a season & a half. Could not clean 300 to save my life, in spite of being able to shoot HM scores at 600 with Nosler 80s.
Switched to Lapua 77s and Shazzaam! High X cleans at 300. Tried some Sierras, again cleaning 300. Bought another lot# of Nosler 77s. They shoot better but still aren't what I'd take to the Nationals.
That’s been the consensus here in our club with 77 nosler several of us couldn’t get them to shoot. I switched to 77 Sierra’s problem solved. Ended up shooting 80.5 begers last part of 2018 shooting season.
