He said good accuracy, so I'd bet that his loads were underwhelming terminally below a certain velocity threshold. For someone who's already used to muzzleloader hunting, I'd say you already have a good idea of what to expect. I, like other folks, took a bit to adjust my mentality/expectations for performance from high speed rifle rounds to slower handgun and muzzleloader rounds. On deer, I've always liked to detonate grenades inside the chest cavity, exit wounds were ofter present but rarely a requirement. Thinking about just punching a hole straight on through took some getting used to.... and I still prefer loads like buffalo bore's "deer grenade" for a LOT of work lol.
