I was wrong, I thought it was .5-1 MOA. After careful scrutiny I misquoted the 1 MOA part.
So let's see what is quoted on the OCW site.
"By "long range" rifle I mean one which can be depended on to hit a 5 gallon pail at 800 yards every time once you know what you're doing. " OCW Website
By the way that is at least 2 MOA.
"Toward that end, 1/2 MOA (minute of angle) accuracy is what I strive for." OCW Website.
Somehow "MINUTE OF 5 GALLON BUCKETS", now known as MOB, is not normally a term associated with extreme accuracy.
Using your NASCAR analogy, you are driving a Yugo at Daytona and thinking your going to win, but somehow have never entered a race, but want to tell everyone how to win!!
Go to www.long-range.com/forums
where the National Fclass and Palma teams hang out. Submit a post telling them how they are all screwed up for not using OCW and you can fix their poor shooting guns. By the way, most of them are shooting 308s which by your website you say you do not even own. When they start preaching it, then I will believe. They like to use the dirty nasty chronos in load development too so you have your work cut out for you. Until then just unproven internet theory, no matter how many flies someone shoots.
Besides IF that can gun and load can repeat that performance (and is not the blind hog finding an acorn) then bring it to any match (BR, Groundhog, Egg Shoots etc) and clean up.
As for explaining why some guns and some bullets shoot better in the lands vs at mag OAL, cannot. Nor do I have to as it does not make it untrue, you cannot explain why they don't either. The match results speak for themselves.
Many of these BR guys put more rounds downrange in one year than you have ever pulled the trigger on. The short range buys shoot groups in the ZEROs and ONES and not MOB. 1K BR matches are won normally with groups under match conditions(normally windy) in the 3-4" range for LG (5 shots) and 4-5" for HG(10 shots).
Bullets are tested all up and down from .040 in the lands to .040 off. We load to where it shoots best, but 1000s of bullets downrange, certain trends start to develop that even Ray Charles can see but they cannot quote engineering theory and they do not have a website for MOB accuracy standards.
If anyone wants a MOB gun, then OCW with its grossly uninformed reloading internet theory is the place to go.
