�If you add a few more grains of powder to a .45-70 load that's "Working Well", one may see the REAL accuracy potential from a well managed BPCR ,....one QUITE beyond what's been posted, thus far.�

From �Modern Observations On Rifle Shooting�, by Edwin A Perry (3rd. edition, 1880), p. 17:

�The capacity for rifles to burn powder is widely different, some rifles reducing elevation until 110 grains have been used, while other do not change elevations for any amount over 95 grains.Find the capacity of the rifle and then use two or three grains more.� (Italics added: rcN)
