Over a couple of days, I loaded several different loads and accidentally loaded some 310gr 44M cartridges with 23.5gr of H110 (An FA only 45LC load) instead of 21.5gr (Ruger/TC/FA 44M load). Fortunately the SBH is extremely strong. In fact, I only realized the problem after I shot 100 of them and went back home to load more and checked my load log. You can't be too careful. Maybe you can't be careful enough?
