I would tell you that what works in a particular rifle "might not" work in yours. Never ASSUME when fingers and eyes are at stake. I`ve had barrels that went over max suggested loads for a velocity target, and never got there,a 308, and barrels I started 2 grns, under suggested start loads, with velocities well above what was suggested, a 7 Wby mag.
You need to read what your rifle is telling you.
