I don't want to be negative about Thor bullets, but i've used them enough to form an opinion. I won't use them anymore.
Especially, with Bh 209 the Thor bullet needs to be a perfect fit. It's an unforgiving bullet when it comes to fit. A little loose, and you'll get poor accuracy with BH, because BH needs a bullet to fit tight. Too tight with a Thor, and you won't get it down the bore. I can't count how many i've got stuck in a bore when trying to load them. Just .001 will make a difference between too tight, and too loose.
Even if you get a perfect fit with the sample sizing kit. The bullets aren't sized close enough to always give you that perfect fit. You need to size them yourself to get them all the same.
The last problem is very annoying. He always runs out of them. I think Barnes makes one run a year for him, and when he sells them all he's out for the rest of the year.
Good performing bullet when everything is right. Just too much trouble for me. I cured the problem by using the muzzleloader in rifle seasons. Now I can use any bullet. If I had to hunt the muzzy season i'd look into the new Federal bullet.
Just my .02. You don't have to agree.
