Has anyone used them in their flintlock? I have used 300gr version of them in my inline with excellent results. I was not sure if flintlock velocities would be great enough for them to expand and be utilized to their full potential. Thanks!

I can't get over the price of them, though they look absolutely wicked. If I were hunting something as large as a moose, I think I'd try them out but I don't think I can justify the cost of them on whitetail. I've had good results with Hornady SST out of my Knight Disc Extreme.

I never tried these in the ML. The terminal ballistics are great in the in-line with 2 pellets. Better expansion than anything I have used.

I agree. I shot a couple with my inline and they are quite impressive.
