I am running them out of a 24” R700 5r factory rifle. The load I settled on was 23.5 grains of H4895 seated between.007-.011 off the lands, I don’t have my notes with me but IIRC that puts me in the mid 2900’s. Are they better than 69’s??? That depends. They handle the wind better and require a little less elevation. Fortunately the POI difference between them and my 69g load is .2 mils so I use 69’s for most of my shooting inside 400 yards then switch if going longer.
That said, I tried them in my 223 R700 tactical which has a longer throat and was unable to find a good seating depth to get them under.75 moa consistently...
