Been working on this one recently. If I had more 110 ABs I could confirm this load (things seem to be scarce as hen's teeth right now :grin: )
I built this one on a Savage action.
24" barrel, 2 contour, 1-10 twist.
NOTE: load is safe in my rifle, can't say as to others.
Hornady 22-250 brass necked up and fireformed. (I figure the 22-250 is a 65k psi cartridge so the brass should hold up)
Load is 45 gr Ramshot Hunter, CCI BR (large rifle, forgot the number!) primers, 110 AB with a .130 jump.
Magnetospeed 3 shot avg 3111 fps, SD 8. (From loads as I was tuning it in)
