I've used their product in 277 cal. In a tight bore they were great shooters and were great for yotes Locals used them on elk with good success.
I sent a box to a fella in PA with a great shooting factory Winchester 270 WSM and they grouped in inches instead of portions of an inch. Hence the necessity of a tight bore.
Also, if removed from the case with an impact bullet remover the bronze point as often as not came out.
ALso the going price then was 2 bucks each which was kind of a downer but now that I know what I'm supposed to be doing I don't shoot nearly as many bullets as I did in the past.
