Okay here's an update. Note I'm only updating in case this helps other shooter with 1-14" 22-250 that is finicky or burned out like mine. I bought some 55gr vmax flat base in the hopes that they would shoot. They didn't, two inch groups with my pet load of H380. I'll try two more loads but if they don't shoot I'll just save them for my AR15. I did contact a varmint hunter on another forum that uses the Berger Match Target Flat Base 55 gr with his 22 Nosler and loves them. Say they are very devastating at 3400 fps. They are advertised as being good on varmints so that's what I'll be using this spring. I'll give terminal results when I get some results.
