Guess what showed up last week...





stay tuned.... shooting tomo.... more pics and thoughts to come soon!

[ShadowPeo]

Nice, I want more pictures

Try to get a pic of the illumination as well please!

Guys,
First production batch of AMR reticles are done, we have had them out on the range since we got them two days ago. Here are some of the pictures that we have taken so far.

Here is illuminated reticle:
@24x

@10x



Here we are aiming at a 1/4" dot at 100 yards to show what the reticles center section looks like as some worried it wouldn't allow precision aiming.

100yds @ 24x

100yds @ 10x


Here then I covered up the 100 yard targets with the lower grid system to show how much it obscures target viewing accuracy.
@24x

@10x



Yellow target is 500 yards out. I posted two standard sized blue office sticky notes on the steel one on the head and one center mass. You can see the center of the crosshair aids in aiming at small objects.



So the reason for the grid system is for holdovers so we didn't do any dialing for elevation or wind the entire test. It was very quick to find grid locations with the clear numbering systems. Our aiming point at 500 yards was the sticky note on teh head and our dope was 2.8 mils up and .5 mils left. Note how easy it is to aim to .1 mil accuracy with the grid and how it doesn't obscure the small blue sticky note like it would with a standard crosshair.



Here we are shooting a rock at 900 yards @ 16x our dope is 7.5 mils up and .5 mils right. I should note that it was super fast to guide the spotter to the target rocks we were picking out because of the grid system. By powering down to 6x and measuring mil distances from reference objects to the targeted rocks it cut communication down a lot. I also wanted to do a rapid fire test to see how fast I could reacquire the holder over on the grid and re-engage the 900 yard rock. I fired two five round strings as rapidly as possible and hit the rod every time. It was very fast and not a problem, especially with the numbering system that kept me from having to count mils down from the center crosshair.



Last point of interest was it made it quick to zero. I mounted the new optic on a new 308 win 22' SRS demo rifle which had not been fired previously. It took me three shots to hit cardboard at 100 yards once on cardboard I overlaid the grid to measure precise distance between where the shot landed compared to my aiming point. I corrected the distance which was about 5 mils low and .6 mils right. I dialed the correction then took my next shot at this target hitting just .2 mils above the 1/4" dot. I measured the .2 correction and dialed down and shot five rounds center mass. Now there was a fair bit of mirage so it isn't my best showing but the 5-shot group size hovers around 1/2' (excluding the sighter high sighter shot of course)

In the first tests we did overall utility of the reticle and its holdover capabilities. Tomorrow we are going to do precision milling of distances and testing the range brackets. Just in what we have tested so far milling to .05 mil accuracy is going to be a piece of cake, heck you guys can see .05 mil accuracy in the pic's that I just posted.

[Orkan]

Is there a spec sheet for all the subtension measurements you can post for us?

[db_17_85]

I'm certainly curious about the ranging lines. What size target are they calibrated to?

[Orkan]

Everything looks .2 mil to me.

The range estimation lines look like 18" chest. Confirmation on that Dan?

[db_17_85]

So I finally thought it through and did a little math. The 400 line is roughly 2.5 mil above center. That would equal out to a 36" tall target fitting underneath at that range. I would assume that Orkan is correct or damn close on the widths then.

[Nicholas]

dots and small hash marks are 0.2 mils that is correct. I am working on a diagram but have been too busy this week to get it finished.

The gaps in the center 1 mil are 0.1 mil gaps.
