Yes, one can't- but that caution also applies equally to two, or WTH- even three- My grandfather always told me that. I never shoot reloads in my M12's at our club's tower pheasant shoots (note, I said "shoots" not "hunts"-- In the rush of the multiple flurries of "ditch parrots" getting airborne from the elevated tower- if you had a wad from a poor reload stuck mid-way uppa da tuba- and then followed it by firing a freshly chambered factory load- recipe for a disaster.
