A 270gr at 3000fps is going to be a tall order. Especially for a monometal bullet at that.Maybe I’m pushing my AI a little hard…..but, I’m getting 10+ loads on a case, no heavy bolt lift….however, do have flattened (not cratered) primers and very light extractor marks. Heck, I’ve seen these examples over the years with factory rounds in various firearms.
My present hunting load is a Barnes 250 TTSX @ 3130 mv and darn accurate. I went to 3160 mv when developing the load …..but the groups were starting to open up some. I figured that 3130 mv with a 250 gr. bullet was pretty decent. Maybe I just have a “fast” barrel!
I finally got some 270 grain LRX’s and hope to develop a good load this summer. My goal is an accurate and safe 3000 mv. I’ll be pretty bummed if I don’t get there!
I respectfully suggest that….I don’t think the Ruger can get there! memtb
