I've been doing my best to stay out of this squabble but you guys are getting weird.
Your all right.
Your all wrong also
A load capable of 1 moa at 100yds is not capable of 1 moa at 300yds just because its easy math.
Theres a gazillion things that happen in those last 200yds not even including the wind.
Going backwards to Freds contention lets think about this.
300yds is considered by most to be the magic point where short range accuracy ends and ballistics begin.
Es and SD (whicever you prefer) really JUST START to become important at 300yds in most modern centerfire high performance cartridges.
A debatable point I'm sure but you don't see many short range Benchresters worried about chrono numbers and they're variations.
Smallest five shot group I've ever shot at 100yds(.048) had over 200fps ES. Figure that one out.
Es and SD will start messing with a group at 300yds.
Neck tension variables do more to mess up groups at 100yds than Es will at 300. Maybe not every load, every gun, every bullet but I've seen enough to know POI will change with neck tension. Even if ES remains averaged.
Lets cut it short and get to Freds contention. An accurate bullet all by itself is indeed accurate, Yes
Take out all the other variables and it is still an accurate bullet. Maybe THE most accurate bullet
Other projys may cut the wind better. Other projys may handle ES better. Thats simply ballistics.
For the shooting I do (100-300yds) I choose the most accurate bullet not the BC.
Accuracy first and worry about the wind later is my choice. YMMV
1 moa @ 100yds = 1moa at 300yds. Noone could tell the difference with that type of accuracy.
Take out all the variables, BC, ES, wind, tension and anything else that will cause a group to disperse.
All outside variables removed a bullet capable of .01 moa @ 100 is still not likely to shoot .01 moa @ 300yds.
Why not? No five bullets are perfect.
Throw in a little non concentric jacket, meplat in the mix and it will be seen downrange more than up close. Simple as that.
I agree with Jim. Many loads that shoot well at 100 don't seem to do well at 300, even 200.
I've also seen factory guns capable of .03 moa @ 100yds shoot .02 moa groups and less at 300yds with low BC bullets. Conditions will always change and that magic disappears fast.
Sometimes you get lucky. Sometimes the wind blows em all in
Does'nt happen often enough for me.
Where the he!!s BCB when you need em! He knows this stuff a million times better than I.
