it doesn't matter ---- 15,25,50,75,or 100 inches,feet,yards are the same distance zeroed in or not

TOO many freaks and NOT enough circuses

I use holdover/mildots, so that comes next.

I'm using a 3x12x44 Accushot. I focus at 100 FT.(for my zero)25 -26 yds, using the mil dot to focus spot on. Then I'll finish the rest of the yards.10 thru 50. Kind of hard to focus at 50 with a 12x. I learned that from Scott Hull.

20x. Now I have the same scope as you. I presume you are shooting Hunter Rifle? Zeroing my
rifle and pistol I use the same method...

Using Brad's trajectory calculator and inputting all the pertinant info, I look at the mid-point
trajectory usind an arbitrary zero. I then adjust the zero to keep the mid-point at 1/8" or less
above line of sight. This will give you a very long zero aim point. Shooting near 20fpe, you
can have two points of zero holdover, (near and far). Possibly as much as 17yds or more in between. Hope you can understand my explanation.

Kind of an oddball way of doing it, but it works really well.

I have found the Leapers Swat 3-12x44 to range really well. Especially for the pistol distances.

I personally haven't done it but have considered the sidewheel configuration many times.... I am mostly into heavy, target, benchrest, sniper kind of shooting as apposed to lightweight, fast handling, low magnification, hunting, plinking..... My 10/22 and my heavy marksman stocked 392 weigh 11 pounds+... On the occasion that I shoot offhand the adjustable objective is very difficult to operate... Welcome to sidewheel... The reason I considered calibrating a sidewheel is when I saw the way a side focus KNOB was marked... I was thinking for accurate focal rangefinding that the knob wasn't wasn't very incrementally accommodating due to it's diameter and that the AO could be better in that respect... Until just now I never though alot about a sidewheel being inherently more accurate due to its diameter but more for the convenient operating capability but it is definately more accurate.... IMHO I would think that you should calibrate the sidewheel to known set distances focally first.. That way you can accurately compare ballistics generated electronically.... Greg

who dont need the level of precision we do. So you make the knob bigger (adde a wheel) and it increases the resolution for your yardage marking.

Ive some some collars for AO use, does the ame thing except at the front. eh, figure its persoanl prefernce

and you can save your self a lot of hassle if your grab a couple of cold ones and play "what if" with it for a couple hours.

has hashes instaed of dots, and a range finding gizmo below the last dot, but I'v not figured that out yet (and may not bother)

Red, green and BLUE for illumination. Blue is great during the day time

Charigun says 35 or 40 yards would be the best for a OPBZ (Optimum point blank zero) but they generate differnt aim points at the 0 - 55 ranges. I'll have to rerun the numbers an report back, butt IIRC the longer disatnce spreads the aim point over a much wider set of dots , above and belwo the cros ahir. the sorter distance groups the ranges  (25 - 40 yards) much closer to the center dot.

Ive used 35 yards as a xzero on my leapers 6-24x50 scope and it workded well.\

this scope will almost focus down to 10 at 40x yards, does so enough you can see the center dot on the Shootnsee targets.

I'd hate to have to shoot a rifle with the scope so high off the barrel to fit a wheel or a collar on the front AO ring.

Once again, I'm probably missing something....

I plink, therefore I am.
