So I assume you have used these bullets with great success, being as you recommend them?
I have used them, but in all honesty I have used Bull Shop Conicals more. Both bullets are made from the same mold. The real differences are in the lubes used.
They are very accurate and they work very well on elk or deer.
This doe was shot with a .503-460... a way over match for a deer but it was what I had available.

This buck also met a .503-460


We can use Power Belts in Idaho also but it really is not a bullet that I would recommend to anyone. It is accurate that is a positive but you really need to reduce the powder load to keep it from coming apart insde the animal.
