Re: Precision Shooting 1-Part 1: The Basics of Your Rifle
I cannot find a help section to this forum, or any button that allow one to start a new thread. Is it possible for a user who is logged in to start a thread or do you have to have some kind of Admin privledges?
Posting this subject here because I haven't found another thread that is more appropriate. Here's the question:
If a gun is shooting say 1 MOA at 100 yards, ASIDE FROM ENVIRONMENTAL FACTORS, can we expect it to hold 1 MOA down range at 200, 300, 400, etc?
I was talking to a gunsmith at the range today, and mentioned a guy who said the AR he built easily shoots 1 MOA, or 1" @ 100 yards. The gunsmith said, "Yea, maybe at 100 yards, but it probably won't hold that MOA at 400 yards."
WAIT! I thought any disproportionate spread downrange was because of environmental factors such as wind, heatwaves off the ground, etc. But he said the bullet, though stablized at 100, might not be stable at 300 because of resonant vibrations in the barrel, bedding issues, etc.
OK that means to me what he is really saying is that 100 yards is not distant enough to sample bullet stability. Is that correct? Is what he is saying correct?? Can you have a gun that shoots .3" groups at 100 yards, but shoots at best 6" groups at 300 yards??? I thought our calcuations can be linear, so .2" @ 100 will yield possible .6" at 300 and so on. He is saying that is not correct.
If there is a disproportionate variation in degree of accuracy after a determined degree at 100, I CAN imagine that being due to bullet design, BC, or other things related to the bullet itself, but not because of the gun.
Any thoughts on this, LR Shooters??
And how does a lowly user start a new thread here??
