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 :)
