Your velocity looks good which corresponds to my results with Retumbo & the 120gr TSX. Would like to see how your rifle groups with this load. Mine grouped poorly with this powder/bullet combo. With 7828 I got a similar velocity but with sub 1/2" groups. Different barrel vibrations???
Barring any interruptions/bad weather, I will shoot the seating depth test this Friday. The Chargemaster Lite is on right now, warming up to load the ammo for Friday's range session.
