Has anyone any experience with these bullets? How is performance at long range (5-700 yards)

Thoughts?

I have some but never hunted with them. Way too expensive and way too long. They really steal case capacity.

Maxx , you got a better bullet maker right in Canada He is Richard Graves of WildCat Bullets . His bullets have a High B.C. just like lost River. Call him he will make the bullit you want not as bad a cost as LS. I shoot his 7 mm bullets.
