I just purchased a Ruger M77 (low serial, tang safety) 220 Swift with 26" BBL. I also reload for my .223 and have alot of 60gr Vmax bullets that I can load, However I'm wondering if the twist rate is 1 in 14 for this old Ruger. I have heard there have been problems with twist rates in this specific caliber for loading higher grain bullets. I also have some IMR 4064 that I would like to load with these bullets and work a load up. My estimates are to start with about 35gr of IMR 4064 and work up. Anybody have ideas on this? This is my first 220 Swift but I have dreamed of having one my whole life. Just some thoughts would help. Thanks guys, Keep shooting.
