Standard pressure loads are OK, if what you mean by "standard pressure" is that they do not exceed about 14,000 psi or so.
A toggle link rifle such as the 1860 replica will require BP duplicate loads as explained above. A good load that has been used for many years to duplicate factory .45 Colt ballistics and pressures is a 250 grain bullet with 8 grs. of Unique. I have fired several thousand of them out of two toggle-link replicas, an 1860 and an 1866. No problems, and you get about 1000 fps from a rifle barrel. Hit a deer, hog or black bear in the right spot with one of those at 100 yards or less and it will be time to break out the skinning knife.
