I was wanting to shoot 1-8 twist with the heavier bullets. Was wanting everyone's thoughts / recommendations. I currently have a swift and love it but it is set up for the 55 gr bullets. I was hoping to shoot 70-85gr bullets in the new rifle. Does anyone have experience shooting the heavier gr bullets out of a 220 Swift? I am considering 22-6mm (224 TTH) instead due to velocities but I like the ease of using just factory 220 Swift brass instead of having to form brass from 6MM. Your thoughts?
