Bushnell BTR-1 reticle WTF?

[Disciple]

I am looking at this reticle design and I think something is mislabeled or broken or I am nuts. Shouldn't the bar labeled 200 yards really be 300 yards? How can there be a 4.36 MOA drop at 200 yards from a 100 yard zero?

According to Strelok, I get about 1-1.3 MOA at 200 with a 100 zero, depending upon muzzle velocity and whether it's 55 or 62 grain. Doesn't match up with the reticle even that line was 300 either. Way off.

Bottom of the dot/top of the post should be 200 yds...then 300/400/500/600 yds??? Probably just a misprint.

I matched their MOA values assuming the bars are 300, 400, 500, 600 yards with these parameters: 2875 FPS, 1.5" sight height, BC G7 0.166 (http://www.shooterscalculator.com/ballistic-trajectory-chart.php?t=acbb0f67)

That misprint is throughout their documentation, printed and electronic.

Looking at your data, what Bushnell says is the 200 hash, should actually be the 300, moving 200 up to the top post/bottom dot looks like it would work MOA wise. the second from the top hash fits 400 MOA wise, the last 2 hash marks fit 500 and 600. Those last 2 posts don't fit anywhere, maybe like 450 and 550 idk.

I don't know about this reticle. But it would not surprise me if Bushnell made a mistake with it. I noticed a similar and more obviously wrong mistake with another Bushnell BDC reticle.

The P4Xi reticle is mis-labeled in Steiner’s literature. The reticle looks an awful lot like that one. In the case of the P4Xi, the dot is 200, but I can’t remember if it was labeled as 100 or 300.

Bushnell and Steiner are close cousins these days.

Edit: try a few different zero ranges with a 68-70 gr bullet in your calculator.

Edit 2: I looked at Strelok; this reticle is much stranger than it first appears.

I was able to fit the four horizontal bars as 300, 400, 500, and 600 meters. MV 2875 FPS is given. 1.5" sight height is unrealistic but commonly used on ballistic tables. BC G7 0.151 is from M855. I get a fit using atmospheric parameters: 65.0°F, 29.92 Hg, 50% humidity, 2800 ft altitude. In https://www.jbmballistics.com/cgi-bin/jbmtraj_simp-5.1.cgi What does Strelok give for these values?
