Home Forums Hunting & Shooting Ask The Gunwriters Am I Just Lucky?

I [b][/b]have a question regarding duplex scopes.
I have 3 rifles that all perform the same way.

1)An Abolt 30-06 shooting 180gr nosler partition PP over a max charge of IMR4064

2)M70 .375H&H shooting 260gr nosler partitions over a max charge of IMR4895

3)Savage 11 30-06 shooting 180gr TTSX over a max charge of Superperformance

All three sighted to hit point on at 200yds, (slightly varying amounts high at 100yds) but they all also print dead on at 300yds, if I use as an aiming point, the part is the lower vertical cross hair that is the arrow portion where it goes from thick to thin.

Am I just lucky, or was this purposeful from the scope manufacturers?

Scopes are two Leupold VX III and one Nikon Monarch

Sorry for the confusion. I meant they print dead on at 300yds using the arrow portion of the duplex!

Easy to check out. Set up a graph paper, marked in inches, at 100 yrds, exactly, turn the scope up to full power, see where the "point" falls, inches low, then refer to your known ballistic chart.

I have several 308s set up that way with simple scopes. For my hunting it makes things quick and easy.

Again I think I was confusing. I know where it prints at 100 and 200. What I find interesting is that each rifle/scope combo prints dead on at 300 where the lower crosshair becomes thicker.
It’s incredibly useful.

A lot of ballistic info missing but yeah, nothing amazing figuring a 7.6 moa subtension...it is amazing that it is in your words "dead on" at 300yds. I've never been that fortunate. I would guess that 7.6 moa subtension was no coincidence on behalf of the engineers.

The issue that you are going to have is that it is that way when dialed up to max at the bench. Try it when it is set at 5X (or any X below max) and the results will be quite different.

You just have very similar ballistics from those three and they just happen to work with your scopes. The 375 is just an overgrown 30-06.

At one time, I knew at what level of magnification to set the 1-4 Leupold on my .45-70 Guide Gun so that, when sighted in at 100 yards, the lower "point" of the duplex would put me on at 200 yards.

I guess I’m just lucky. I have a Savage M12 (varmint style , heavy fluted barrel) with a 4.5-14x50 Ill. That has a fine crosshair, a space, then mildots. The bottom of the crosshair as an aim point is exactly where my bullet lands at 300yds when it is sighted dead on at 200. That rig shoots 165gr Nosler ballistic tips over 43grains of IMR4895.
It’s my only load that isn’t max, but it is way more accurate than I can shoot it. I borrowed a fellow’s chrono one day at the range and it was 2616fps. I’ve used it to take make 40 NC sized deer. Only 1 made it more that 30 yards.

"Dead on" to one guy, may not necessarily be "dead on" to another guy. Just sayin. His dead on may be like many others where if he's on a 12" steel plate at 300 yards, that is good enough.

True that. Find the power that puts the tip of the bottom tapered crosswire at poi at desired range and you've got a useful second aiming point. Write that power and range down.

No, I mean dead on at 300. If the wind isn’t blowing, and I do my part (the harder thing to count on!), I can put em in a 3-5” group at the aiming spot at 300 using that point to aim. The Abolt has a heavy duplex so it is a hunting scope not a target model.

Deer hunting in NC is often a last minute of light deal and I find a heavy duplex or illuminated scope necessary.
