Running 120gr is kinda limiting the capabilities of the round. But if that’s what he wants.
My final loads for the 140gr Berger was 53.5gr Vihta N165
For the 143gr Eld was 55gr Vihta N560
I also tried Re26 and 2209 both were ok
This data won’t help mush with 120gr pills unfortunately.
Banging into QL a few figures (all related to my rifle) a Max charge of 60.5gr Re26 will give a 98.2% fill 100% burn at 3315fps
Running your AR 2217 at 62.3gr max your at a fill of 110% with a 98%burn doing 3239fps
Looks like AR 2213 would be worth a try 58.3gr max 101%fill 98% burn at 3251fps
*****All these are MAX charges with my rifles measurements*****
Hope some of this helps.
