Most 22-250's I have shot will shoot with H380 and 55grn projectiles. I will not quote a load for this, but you can look them up and find more loads than you can shoot in a month!!! Try on H380, Varget or IMR 4064 and most 250's like the 50-55grn range. It will run you in the 3500-3700fps area. GREAT 'Yote slayers!!!!
If you are wanting more velocity, you can go the to 40-45grn area, but will gain more wind drift and loose energy at the longer distances.
You will also want to keep an eye on case length as you go. It will have to be trimmed more often the hotter you go for the brass flows more easily. Good shootn!!!!!
