RL23 and range reports

[Taco280AI]

So what's up with my scope? Zeiss V4. **or what am I doing to mess this up**

I first shot at 200 yards, 1" left and about .4" high. Grouped .95"

Moved to 250 yards, went 2 - 1/4 MOA clicks right and it ended up 2.5" right.  Acting like they're 1/2 MOA adjustments.

I also went 1 MOA up, which should get me a little high on target, but I did fail to factor in that it was already a little high. Still, it ended up 2.25" above the target when drop should be 2.3" (confirmed on another target when set back to zero). So that 2.25" and 2.3" of drop is 4.55" when I only moved it 1 MOA. It should only have moved 2.5", not 4.5"... almost acting like each click is .5 MOA.

The target not shown, also at 250, I went back 2 clicks left and 4 down, same setting as the 200 yard target, roughly 1.25" left and 1.75" low (when factoring in the .4 high at 200 it comes out to about where it should be for drop).

Back at it tomorrow...

Tall target tracking test

[Magnum_Willys]

Quick check: If you can secure your rifle on bags, bench, etc look at cross hairs while pointing at  spot on target.  Now turn turrets to line crosshairs up on a spot 10” higher - how many clicks?   

[hunterofelk]

I don't think scope crosshairs always move in exact increments.  I read one article about lightly tapping on the turrets after moving or going the distance you want then going back to the old position and then back out again.  Also, once you start going out in range a lot more can happen to the bullet as far as wind is concerned.  I have been out of school a long time so I forget how adjustments to sights change exponentially over distance.

[Magnum_Willys]

Its approximately 1” at 100 for 4 clicks (1/4” per click) or 2” at 200, or 5” at 500 for those 4 clicks.

So 2 clicks at 250 should be 1/2” x 2.5 = 1.25”

I would try to zero at one range before adjusting zero between distances.

Its approximately 1” at 100 for 4 clicks (1/4” per click) or 2” at 200, or 5” at 500 for those 4 clicks.

So 2 clicks at 250 should be 1/2” x 2.5 = 1.25”

That scope also should have subtensions in the reticle. Use those instead of trying to figure the inches. If the scope reticle shows it needs to move 1/2 moa move it 1/2 moa.

I think I just suck. Not sure what's with the horizontal adjustment, but split the difference and now it's centered. Shot today and vertical was pretty much on. Fundamentals... I need to work on them 

[Taco280AI]

User error before. Shot at 400 this morning, slightly off on elevation from expected, but I've seen that a few times now so I'm wondering about actual BC vs advertised.

First fouling shot, low. Second with 17 clicks, 3rd and 4th with 18. 5th shot I held on the left side of the target for wind. Had I held the same aim as before it would be where the red dot is. I'll play with numbers to get the trajectory to match up with actual results.

If I move shot #2 up one inch for 18 clicks instead of 17, and (correctly this time) moved the red dot where it should be - a little farther right, then that would be right at 2.0 inches, 4 shots @ 400 yards. Half MOA hunting load with a Barnes LRX 

Leaving it dirty and hunting Idaho deer tomorrow 

[BULLBLASTER]

  that looks like itll work!

Good shooting. Here is my 400 yard target from yesterday, same bullet in 7mm rem mag. Hoping it will find meat on Thursday next week in Idaho.

.25 MOA is the best you can do? Good luck hitting anything 


What rifle? That in a field scenario or off a bench at the range? Damn good group

This was off a bipod with my bino harness as my rear rest, laying in a gravel road. Honestly, the 300 yard group was maybe slightly worse than this, so I have to assume that there was at least a little luck involved in that group, probably more than a little. 

Rifle is my 20 year old Ruger M77 MKII, but it has always been a tack driver.
