I am thinking of getting a Bond Derringer for concealed carry as a backup and in hot weather and am leaning towards the .45LC as it appears it is the most potent load. I would like the 4.25" barrel. Can one load both chambers with .45 Colt instead of 1 with .45LC and 1 with .410? I have no interest with using .410-about the most useless PD load there is IMHO. Thanks
