I bought a 100 ct box of 105’s for my father’s 6GT….satisfied with the results, I went and purchased a 500 ct box…base to ogive went from .580” to .600” consistently….seating bullets for same jump, I’ll now have .020” more bullet down in the case…how should I expect this to alter my groups? Do you expect I’ll need to start over with load development? BTW….website says base to ogive is .624”….that’s .040” off from my first box! Seems like an awful lot to me!
