Actually, I don't think Mr. Garrett convinces anyone who reads that material with an open mind. Instead, be provides justification to those who prefer to use a 45-70, both in applications where it is appropriate and in applications where it is not.

If Mr. Garrett were right that less velocity equals more penetration, then I would have to ask why he loads his 45-70 ammo hot in order to achieve near max. velocities for the cartridge. If less velocity is desirable, it surprises me that he does not load the 45-70 to mild pressure levels because the velocity would be less.

There is one interpretation which makes Mr. Garrett correct, however. Perhaps he loads his cast lead bullets to the maximum velocity that they can withstand. Perhaps if pushed to a higher velocity, his cast lead bullets would deform or break up. In that event, the Garrett cast lead bullets would enjoy less penetration if pushed faster.

Of course all a fellow would need to do to achieve better results is purchase some DG solids from A-Square, Barnes, GS Custom, Hornady, North Fork, TCCI, Trophy Bonded (Speer), Woodleigh. With those bullets, velocity does not become a limitation again (due to deforming bullets) until above 2500 fps in most instances.
