i shot those old silver tips in 30-30 , 270 , 30-06 and i liked them . i tried then new ones in a 7mag with the black coating and they wouldn't group on a 12"x12" target at a 100 . the gun was shooting less than 1/2" groups .
I had great accuracy with both in 257 Wthby and 7mm STW. Sub MOA and the 257 Wthby had over a 1000 rounds thru it with that bullet. From H1000, H4831SC but ended up with Reloader 22 being the choice for both. Some were 5 shot groups, not just 3. Had friends doing moly coating at the time but the lubalox coating wasn’t ever and issue.
Both rounds were running over 3450 for averages.
