Help with load data for cast 210gr RN

Post by ShippWrekk » Mon Jun 29, 2020 6:26 pm

So I bought a Lyman double-caviity mold for a 210 grain round nose, gas-checked bullet. I hope to achieve a velocity of around 1050 fps. I'm using Hodgdon CFE BLK powder.
I recently loaded a Nosler 210 grain HPBT with 11.8gr at an OAL of 2.250" and go excellent results. Is this a good starting point? Or not applicable.. thanks in advance.

Load it no different than you did the other bullet.

First find the length that hits the lands for you max length, then see how the same weight powder charge sits under the bullet at that length. This will likely shoot faster than the jacketed with the same charge, just adjust accordingly.
300 Blackout, not just for sub-sonics.
