H 4350 has been slowed down in burning rate since it was introduced as AR2209 whereby I have seen velocities as light as 2880fps using that 62gn load.
This makes it safer from the manufacturers side, but unless you use a chronograph continually, it is harder the monitor the variance in powders either by batch or over time.

I do get very fine accuracy using that 62gn charge but when velocity is the goal, that is where 760 proves ideal with 3080fps usually obtainable from a grain less.


When truth is ignored, it does not change an untruth from remaining a lie.
