I have noticed over the years some factory loads just seem a lot hotter to me. Since I don't have a chronograph this is all subjective. They just produce a lot more recoil and muzzle blast. I have noticed it mostly with .357 Magnums. Some 125 Grn loads have a lot more recoil than the 158 Grn ones, at least in my guns. They are considered some of the most effective loads in this caliber.
By the way, the only stupid question is one you don't ask. At least that's what I always heard, but I never asked about it.
