I've been planning on getting one sometime soon for muzzleloader season. Has anyone here used one? What's your opinion of it?

I have one, put a bushnell scope on it. Super accurate with 80gr of BH209 an 300gr XTP/crushrib sabot. I plan to hunt with it along with my White this fall.

You will need a rest. I use a shooting bipod. She will kick some too, so be ready, but its not really that bad just hold on.

The kid uses a TC pistol in .300wm toytruck. I don't think recoil from a ML pistol is going to bug him too much

I shot a 30-30 contender and thought that had about enough kick I could only imagine shooting a .300wm. I shoot that as a rifle and not sure I'd want to as a pistol lol.

I have 2 .500 S&W's, one 4 inch one 8 inch. The 8 inch is scoped and of course longer so it's heavier. Shooting it isn't quite a "pleasure" but not to awful bad. The 4 inch on the other hand, is tantamount to holding a kicking, screaming, biting, thrashing 4 year old. But that 4 year old is awful mean on the business end I would imagine that .300wm TC that Lone Wolf uses would be about the same!

I would like to try shooting a .500 once.

Recoil is about the same as my .44 mag. Ruger revolver, just don't let it surprise you because is a muzzleloader.

LOL with what he is used to toy, it would probably have to buck like a full grown cranky mule for him to even notice the recoil

I would love to get one if they made them in 45cal. Ed's little 350gr conicals would be a hoot and easy to load too.

.45 are now legal here, but .50 is recommended by DGIF.
Go ahead an get one they are a hoot to shoot, just use a .452 saboted bullet.
