Been using the various 4831s for 55 years but a friend recently tipped me off to RL16.
I loaded two rounds of 130TTSX each from 52 grs to 55 grs in 1/2gr increments and tried a ladder at 200 yards.
All rounds fell within 1.5" with no discernible elevation difference. I had loaded 4 extra max loads at
55 grs and moved to 100 yards. Three shots were .265 and the 4th shot I hung my crono on the barrel
and it was off a 1/2". Crono was 3160fps.

Primers were Federal Magnum and brass is Nosler. The TTSX was seated to mid of top groove.

I'm going out this afternoon to see if this is dumb luck or repeatable.
