I have a 24 inch shaw fluted bull barrel, what is the best grain bullet to use for 100 to 200 yards

                                                                      Thanks copdills

I have fired sub MOA with my 1 in 8 RRA from 45 g up to 77 grain. I have not tried anything above 77 g.

Thanks for the information 357 sig

Every rifle/barrel combination is different. Two rifles one serial number apart may shoot completely different using the exact same ammunition, due to minor, minscule differences in the barrels supplied to the rifle company.

The best bullet weight for YOUR rifle should be determined by YOU, by testing varying bullet weights and powder/primer/brass combinations.

That said suspect the Sierra 77grn. MatchKings will get ya the best groups well out past 200 yards.
(you can buy these as Fed GM or Black Hills factory rounds)

Don't pass on testing the Hornady 75grn. MHPBT round or the Nosler 77grn. OTM though, as they too, might shoot well in your rifle.
