There seems to be a bit of confusion lately about these pills & their performance.
I have fired over 1000 of these bullets now so to be fair I know a bit more than most about them.
I have shot the 420 & 446 in my 416 Barrett.
330,350,375,377,400,402 & 425s in my 375 Rum Imp, 375 Terminator & 375 DCM.
They are a bore rider design, the bearing surface is constant unlike conventional pills.
The increase in weight is in the bore rider length.
What I have found is the speed degrades/increases very little between weights approx 50-100fps unlike conventional pills.
Also the amount of powder reduction/increase between weights is also small, generally 1-3 grains depending on the case & powder used.
As the BC increases the speed decreases at approximately the same rate making them basically ballistic siblings.
The heavy pills still have the edge, just, but it is a very small advantage.
I have found, the advertised BCs aren't that far off the mark.
They appear to be very accurate & easy to tune.
They are a monolithic soft copper bullet with a small hollow point in some of the weights.
I haven't shot enough animals with them to come to any meaning full conclusions about terminal performance.
If you hit bone it is ALL OVER
Also if you hit the stomach they will split from tip to base into several big bits
