Not all manuals have loads for BC2.

Lyman #43 says a start charge of 46 gr. for a projected speed of 2696. Actually, there is no 'standard' for anything less than max pressure loads because it's not really critical. Greatly reduced loads are rarely very consistant because powders are made to work in a given pressure range; really low pressure charges tend to produce variable pressure/speed.

Ball powders tend to have a lot of deterent coating so they often benefit from the use of magnum primers.


"3 rounds each at load increments of .3gr would be a much better use of that 1,500gr of powder."

Agree. Or even two. It doesn't take a lot of rounds to find what doesn't shoot well. Once we find an appearantly good charge is soon enough to try larger numbers at or around that point.
