Hey Allan,
You don't need correcting. There are so many models nowadays that use similar number designations, that it can get confusing. Just like cars & trucks. Chevy has the 1500, 2500, 3500 truck series....and so does Dodge....
Too bad you let that that Ruger 77 get away......their bull bbls. really print fantastic groups with good handloads. My Swift will put 5 rds.(custom handloads) in a 1/4" hole all day. Got a hog at 800yds in upstate New York a few years back.....took 9 rounds though. The 9th one went thru the chest with a puff of dust. I was so far away, the bark of the shot didn't phase him.
Great day to you also Allan....Denny
