Both bullets are copper and shaped like bullets. After that our bullets are cnc latter turned making them much more consistent, softer copper, patented drive band design vs grooved, open hollow point design that gives consistently better bullet expansion throughout the the range of vel down to 1800 fps. Our drive band design reduces engraving force and minimizes contact in the bore resulting in lower pressure and higher vel. our patented PDR drive band design allows us to seal the bore in loose bores and not produce excessive pressure in tight bores. This solved the problems that mono bullets have always had, poor accuracy in loose barrels and over pressure in tight ones. We have almost no copper fouling even in brand new factory barrels. Our PDR design results in inherently easy accuracy with minimal load development. Very rarely is a seating depth adjustment needed to find solid sub moa accuracy.
Our reason for making bullets was terminal performance. We liked the way copper bullets worked on game but always had an issue of some sort with every one we tried. It took us a long time to find the right copper and design that would do what we wanted consistently at high and low vel.
I know it sounds too good. Give them a go, if you are not completely satisfied we will refund your money. Haven't had to refund yet. Only replaced bullets for customers that had the wrong bullet for their rifles barrel twist.
