Hi Shuggie,I'm sure there will be some posts.
I thought what you said was honest,ethical,and good advice.And all the more impressive from a BooBoo (or Yogi) shooter!
There are non custom rifles that will shoot .5 moa,as I'm sure we shall hear.Your point about the non linear group size is typiclly missed though.A .5 moa (6mm,80g@3000fps) rifle at 100 yards will not shoot reliable 2.5 inch groups at 500y(which might be where long range begins,rather than ends).It's more like a 4-5 inch dispersion.The near 100% hit rate for such a rifle on clays,is about 250 yards (assumes no shooting error)
This does make some assumptions-eg that wind reading will be out by 2mph (in 10mph),but also the small,but sometimes cumulative unavoidable physics/field factors/variables. If anyone has doubts,do the math(s),or easier,just accept Brian Litz's math.
Of course,many shooting performances will be better-much better on occasions...but the bottom line remains.
So,thanks for raising this-it needs some discussion,given some of the claims made on occasions-note,there is a lot of real (competition) data...such as Fclass at 600y.
