1 inch @ 100.....1 3/4 inch @ 200!!??

I think that what Horseman suggests might be part of the answer. In the long range black powder crowd a lot of shooters do all their testing at 200 because they swear up and down that the bullets don't settle down till they get out a ways.

Don't underestimate the effect of greater mental focus when shooting different targets either. It applies in large measure to a lot of target shooting. I've seen groups shrink by half for both archers and handgunners simply by switching to targets with a smaller point of focus.

I may have to agree with that, I have little experience with longer range shooting but with archery my 40 yd group and 10 yd group is pretty similar in size. I am sure that it has to do with point of aim etc.
 
I tighten my groups up with my keyboard.:D

You wouldn't believe me how small my groups are if I told you.

I bought a 700 LVSF a few years ago.
First 3 shots trying to sight it in went 0.082"
Does that make it a rifle that will shoot in the 0.1"s?
Nope.
I get a kick out of the ####s who claim 0.5" "ALL DAY LONG":rolleyes:


I've never believed in the 1" @ 100 = 2" @ 200.
Theoretically it should work but there's way too many variables out there.

I just accept good groups.
And tighten them up for the interweb of course.:D
 
I can't say I've ever done much grouping past 100, but the guy's I know who have commented on that phenomenon. Of course the fact that it's noteworthy when it happens, indicates that even then it's not something that always happens, but you are definitely not alone. I won't even start to try and pretend I understand all the external ballistics that can cause that.
 
I had a Model Winchester in .257 Robts. that shoot about 1 1/4" to 1 1/2'' groups at 100yds , not exactly a tack driver, but it would group about the same at 200yds. don,t ask me why. it had a Leupold scope with the adjustable objective the elimenate the parralex.

Horseman described it fairly well. I unfortunately cannot do much better but can recall reading about the British outshooting the American military teams in competition at above 200 yards with the same rifles that were beaten at 100 yards. They found that not only the bullet itself spiraled but also its trajectory due to "yaw" or "wobble". This yaw effect diminishes in some cases as the bullet stabilizes, resulting in better MOA data furthur out in comparison to that at 100yds. Sorry for no direct references or links but try Google & other sites. This effect was also described as minor & in no cases would I expect otherwise.

to reiderate, barrel whip, causes instability. and stability may occur later on after your 100yrds. have you shot beyond 200?

Nope, Only have a 200yrd range. I pretty much shoot to hunt, so anything further then 200yrds I like to try and stalk in on! Like I said before, where i do my hunting 200yrds would most likely be the furthest I'd beable to see!
