JB's .5 MOA AVERAGE for 3,5 and 10 shot groups -
First, that's a pretty fair way to look at it in my opinion, FWIW.
The one thing I'd add to that is that they all be compared at the same range????
I mean, this would mean much different things at 100 yards verses 1000 yards, right????
I really hate dealing with averages though, a cieling, or maximum group size is best IMO.
The other question -
Vertical or horizontal spread maximum????
To me, this means more than group size measured diaganally or whatever, although I record all three.
If a short range BR guy said it should shoot in the 1's, in good conditions, he'd probably be right, from a bench, with flags, in a good solid rest, free recoil likely, with a 6PPC.
Shoot that 6PPC with one of those things removed at a time to quantify how much the group opens up with each of the less than ideal circumstances, then what's it amount to? Then toss the 6PPC for the 300WSM or what have you, then where are you?
3 shot groups (starting cold on each), vertical spread only, 5 groups or more, OFF BI-POD.
Under .3 MOA at 300 yards
Under .4 MOA at 500 yards
Under .8 MOA at 1000 yards
That would be spectacular in my book!
Under .5 MOA at 300 yards
Under .6 MOA at 500 yards
Under 1 MOA at 1000 yards
That's pretty **** good in my book!
Under .7 MOA at 300 yards
Under .8 MOA at 500 yards
Under 1.2 MOA at 1000 yards
Still very good in my book!
Under .9 MOA at 300 yards
Under 1 MOA at 500 yards
Under 1.5 MOA at 1000 yards
Good progress, but I'd work on it more if I thought it'd help. About what I'd expect with a larger caliber factory stick with some load work.
Feel free to disagree.
With a little thought, that's just a wild *** guess based on my experience, nothing more.
I said vertical only, so if wind is a factor you'll have to figure that for yourself. Wind is far too different in every situation to compare with someone elses performance unless you're shooting side by side that day, IMHO. Evaluate yourself objectively and call your shots, works for me.
Ric,
So far, I've got from Boyd that .56 MOA at 770 yards, 3 shot groups, is on average, what his buddies 3 rifles will do, and I think that's about all you're going to get from him. My suggestion is, move on for some more input from those that want to share it concerning the topic at hand.
Darryl does make some good points. Have you any benchmarks for accuracy, Darryl? I know you don't shoot from a bi-pod much, but for the record, what would you consider OK, good, and exceptional shooting from a bi-pod?
I think this is a great topic, and when I first started out shooting LR it meant a lot more to me to know this when I wasn't sure what to expect from my rig. Now, I've got a much better idea from my own testing, others still are very helpfull if all the details are known.
The 5 and 10 shot string accuracy at 1K yd BR are somewhat helpfull to read about, but not really if you never shoot that many in the fast pace they often do, from a different rest, etc. Even less so if you shoot your factory barreled rifle that might be just so-so.
I hope that everyone on the board chimes in here with their perspective on this!
