The same load of 57.8 of H4831 and magnum primers prints into less than a half inch at 115 meters for 5 shots with the Sierra 140's. Velocity is 2900'ish over a chrono
I don't know if the Sierra is a tougher bullet than the Hornady, but it sure gets the job done!
My Tikka likes just about anything 130gn with 58 Gn of H4831 or 53.5gn of H4350 and magnum primers. Pretty much everything will print into at least an inch at 115 meters, but Sierras go into around a third of an inch for 5 shots.
57.8 of H 4831 seems to work with most things 140gn in the same rifle. Accuracy goes from itsy-bitsy holes to around one and a quarter inches at 115 meters.
Once you find a load it shoots well with one projectile, try the same with others.You may be pleasantly surprised
