I am sure that someone has tried these in a reliable ballistics medium such as ballistics gel so I am wondering how they compared. I shoot a bunch of these at normal 38 Special velocities of around 875fps from my 4" guns. Having decided that I will no longer cast I buy the 500 packs of the precast and load them exactly the same. Same vendor for both types usually Lasercast or Proofmark.

What I have noted and the driver of the question is the much greater effect that the RNFP has on our berms at 25 yards. This is very subjective but the crater and the debris spread is about twice the size of the SWC. It is even more pronounced if the berm is wet.

The meplat on the RNFP is a good bit larger than the SWC could it really have that much effect?
