If I was just trying to 'cheat' the seasons, like so many other hunters, I might be interested.
But...
It's far from legal here - for many reasons. (At least for 'primitive weapon' season.)
And I've been using loose powder and patched round balls since I got started.
Even across the border, where it is
probably legal, I'd rather stick with what I know. There is not much to be gained, and plenty to lose, by screwing with routine and muscle memory.
Because I can't and don't really want to use it, I want to knock it and make fun of it. But I can't. I like loopholes, regulation dodges, and people approaching things from a different angle.
The plastic bits do look pretty cheap, cheesy, and low quality. But if it works, that doesn't matter.
Hopefully, quality control is good. My history with Federal ammunition is not good. Lots and lots of bad dimensions and funky powder charges.
Okay, I'll make fun of them a little bit. I just looked again... $2+ per trigger pull, before adding a projectile and primer.
One might as well just rechamber for .338 Lapua.
