Never loaded leads for my 6.5x55, but on the right is my line-up for 45-70. Note that these are .459", not .458
Non-GC lead is 405 gr, the two GC bullets are 425 and 525 gr. BNH on the 2 on the right is 22-23, same as linotype. Unlike linotype, these are not so brittle.
I shoot them all (the lead ones) to the same velocity, about 1625-1630 fps. Notice the WIDE meplats...those guys do not expand, and they do not need to.
I get excellent accuracy out of all 3 of those bullets with RL7
