Discussing power level comparisons between the Hornet and Bee is like discussing who'd win a drag race in a Chevette or an Escort. The beauty of the Hornet isn't how powerful it can be but how well in downloads, only reason I bought one was frustration at not being able to get rimfire ammo. Got some molds, read up and met that goal quickly and easily. In fact, I can't recall ever loading a "real" Hornet load, it's all been reduced cast. I have .223s if I want a real varmint rifle.
Hate to admit it, but I haven't handloaded for that Bee yet. The rifle came with a pretty good stash of ammo and I've shot that. I need to get some cast bullets run through it soon.
