Sorry to bring this up again - I was browsing the forum confirming the "famous" 59.0gr MRP w/200gr Partition load as I am about to start throwing powder.

I cross checked with Nosler's data and interestingly found:

190gr
RL22 - 60.0gr max - 2712 fps
MRP - 58.5gr max - 2769 fps

210gr
RL22 - 57.5gr max - 2646 fps
MRP - 59.0gr max -2640 fps

Seems off that the max charge of RL22 is higher than MRP with 190gr but lower with 210gr. How is that possible?

But, they do show different charges and different results.

Possible? different powder lots. RL-22 and MRP ARE THE SAME/

A good principle to guide me through life: “This is all I have come to expect, standard lackluster performance. Trust nothing, believe no one and realize it will only get worse…”
