Every gun is different, and so is every barrel. How far off the lands are you? I am 50 thou off and my friend is 22 thou off.
I noticed you and your friend are running from 22 to 50 off. I am new to my RUM and reloading for it. Could you please tell me why so far off? I am not trying to be a wise guy I just was wondering if this is common for the round. I have been doing some load work using ( Sunday temp.55 in western pa. )91.5g Retumbo, Fed. 215, 208 A-Max seated just touching the lands, Ohler crono. doing 3100 with a standard deviation of 5fps. out of a 27.5" Shilen select match tube. Best 5 shot 300yd group 1.12". I don't know anything about seating so far out...I don't think this gun will do much better ( definitely not with me behind it ) than it is. But I have others that may benifit....
....Thank's for your input.
