I too have found TC to be greatly superior to RNFP for target loads at 25m - getting appx 700 fps with 2.9 gns Lovex D032 (formerly Accurate No2) in .38 spl cases.

I suspect that the RNFPs will work better when stoked up a little more.

The bullet diameter might be more important than the shape...the Marlin 44mag has a bore stated as 430/431 but most of the commercially available bullets, TC and RNFP are at .429....in fact a box of TC bullets I got with a rifle measured at .428 for the majority. Best to have a few thou overbore size for cast.

The bc of TC cast and RNFP cast seems to be very little different. Bullet diameter and bore size might be more important.
