Theoretically speaking-should group size be the same at various distances?
I have been working on my first handloads. Started at fifty, was getting clover leafs. At 100 yards, I found a load where ONE DAY(the first day with specific loads0 I was getting nice groups.
Went back to the range a couple of weeks later, and wasnt getting anywhere near the groups I was getting.
Went to the range today and shot at fifty yards-clover leaf. I am not a big time shooter. Before I started reloading, I might have gone to the range five or six times a year-so human error can most certainly be the factor.
But what I am wondering, with all conditions being equal-no wind perfect rest-should group sizes be the same at 50 and a 100 yards. Or for that matter, 50 yards and 1000 yards- Removing all human error, removing all wind-everything being equal.
Thanks for any input.

I have been looking for that magic bullet for quite a while, shooting a 1inch pattern at 100y, expecting a 1 inch pattern at 300y. Smiler
In the real world ,physics is hard to overcome.
Quickest way is probably for you to educate yourself on MOA's in relationship to trajectory - distances
You will shoot the same MOA pattern at all distances

The only way you are going to get the same "group size" regardless of range, is if you are shooting in a vacuum, and with no gravity or atmosphere.

I think the only way you would get the same group size under the conditions you gave is if the group size was .000". If the first group is bigger than that it would have to mean that one or more of the shots left the bore at a different angle. No matter how small that angle is, it will continue on out to whatever distance you shoot. That's basic math, er, algebra, er, geometry, er, trigonometry.. Oh hell, whatever you call it.

Now, under those same conditions, though, the group sizes will be proportionate to the range. That is, a 1000 yard group will be 10 times the size of a 100 yard group. Under real-world conditions we all know that doesn't happen. After shooting LR Benchrest for a lot of years I figure the 100/1000 yard factor is more like 15 or 20 to one. Unless you are shooting in Reno where it's 100 to one. Eeker
