I went to the range today and zero'd the rifle at 100 yards. The best group was the last three. All three touching in a cloverleaf right in the middle of the bullseye.
Someone posted about weighing / sorting the rounds and I now understand why
A box of 50 rounds seems to have little clumps of bullets that shoot nearly the same, in no particular order, but sometimes coming in series with one another. It took me a few rounds to stop chasing impacts with the turret but once I did that I could see a pattern forming.
The net result of today's trip was that I now have a drop chart for my rifle (with the ammo I used today) and I know not to expect consistency unless I sort the bullets by weight (which I assume is going to be inconsistent due to powder charge).
Next I moved over to the 200 yard range and did some testing.
The mirage was tumbling around from a 5 - 7 mph wind coming from about 160 degrees (to my line of sight). Downrange, at about 120 yards, the wind was being blocked by trees and the 100 yard berm. At the 100 yard berm the wind seemed to be affected by it.
I put a pistol target next to my intended target to help me find the initial poi. I aimed at the top ring of the target (3' tall) and the first 5 shots hit 36" low. I dialed the scope up 18 moa and fired 5 more rounds. The group was high so I dialed down to 17 moa. This group was low so I dialed in 17.5 moa and shot the last group. Bingo. Unfortunately I didn't keep the target. Groups were in the 3" - 4" range with the best being about 2.5" I think that if the wind would have layed I could have tightened that up a little.
I am glad that I finally made it to the range but I have a lot more fun shooting cow poo in my pasture
Range estimating and windage make it more fun
