Curious having seen and owned a few 36 and 42s in both...what would others think.

One thing to consider, if duplex specs are the same as a gloss 36, a 200 zero should be about right on w/lower post point - at 400 yds.

Would you upgrade the vertical or not?

It dose just that with my 7mm RM shooting 150 gr Bullets out of a Blaser R-93 and a 6 x 42 mm leupold scope. Upgrade if it keeps up up at night. I been leaning to not worry about such things. My current favorite set up is a plain jane 760 Remington in 30-06 with an aimpoint sight. Big Greens 180 gr Core Lokts. The older I get the simpler I want both my guns sights and loads to be. I put more thought into cooking venison these days than what gun load or what have you to shoot it with.

LR duplex with a target turret on the elevation

gmsemel - I agree, good chance such a scope would be riding atop a 243 and see some varmint action which might give a greater variety of shot presentations, distances and size targets. If deer/hogs only I'd not change anything.

The LR duplex works well for many, not used to form an opinion. Target knobs work great, but given choice a M1 w/o worry w/a cap and waterproof would get the nod. An M2 or M3 profile would be great if 1/4MOA.

Just thinking, will likely test to see POI w/lower post downrange.

Yes. I won't have a scope without repeatable adjustments, solid turrets, and/or at the very least mildots.

Na not if your shots are under 300 yards. Heck most of my shots are under 100 yards.

I'd probably do some sort of CDS on a compact 6X33. I tend to prefer low profile adjustments like the current ones on the FX3, 6X42 to the taller M1 or target knobs. They are nice to have as an option.
Over the years, I've found I can do fairly well either holding over or holding into the estimated wind. But I don't do nearly as well if I must do both at the same time.
I would not do a Mil-Dot reticle or anything like one on a big game scope. Too easy to loose the retilce in bad light. E

Agree LBP on those shots, E - the CDS does seem the better option on a svelte little scope.

I just can't warm to the CDS turret. I think some prefer the looks of the CDS, but I like the ease of spinning the M1. If your hope is aesthetics then go with your personal preference, but if spinning is your goal then M1 is the best choice.

Appreciate the input 406.
