Can anyone help me find a holdover conversion from a mil-dot reticle to a rangefinder reticle. They sent me the wrong one and it's too much trouble sending it back and I don't want to mess with incrementing a range target in mil moa and converting it the long hard way by looking through the scope for an hour.

Re: scope reticle unfamiliarity
Without knowing anything about the actual reticle you have, the best I can offer is 1 Mil = 3.438 MOA = 3.6" @ 100 yards.
If you could provide some more useful information about the actual issue, perhaps you'd get a more detailed answer.

Re: scope reticle unfamiliarity
You ordered a rangefinding reticle and they sent you a mildot? Just learn how to range with mil formulas. Or get a Mildot Master. Or a laser rangefinder.
A mildot will be far more versatile than a rangefinding reticle. As long as you know the size of your target, you have a range. You don't need an average sized deer turned exactly perpendicular to your field of view for it to work.
I'm not sure what you mean by holdover conversions. Your holdover will depend on the load, the rifle, and the atmospheric conditions.

Re: scope reticle unfamiliarity
sorry mate, other way around. they sent me a rangefinder instead of a mildot.
guess I use the term holdover right back to the scope, "how many increments do you hold windage or elevation with the rangefinder reticle compared to the mildot" if you already know what you said.
Yes it depends on the FACTORS
Firearm,
Ass position,
Climate,
Trajectory,
Objective,
Range,
Stupidity.
I know I could go mark a target at MOA and range it off, then compare the increments to mildot and make a nice little placard for my plip screen that takes your mind off the shot(the little card you stick inside your scope lid), but that's time and wasted ammo.
Got a mildot master; like it, and ranging aint the problem.
"How many mildots in the reticle equal how many crosshashes in the R/F reticle"?
Here is a link to the reticle view:
http://www.google.com/search?q=ospr...Na--2AWwpOW1DA&ved=0CJ0BELAE&biw=1024&bih=684
Look at the blue picture. Of course, THE INTERNET says a TYPICAL scope uses 4"@100yd but that blows mildot away for a long time field proven constant doesn't it.
They say that the width of a reticle line is 1 MOA but that don't jive considering you'd have to wave the line 36 inches updownsideside a lot at 1000.
If I can't find an answer, no worries mate, I'll just find some time and and environment fitting and go shoot the damn thing.

Re: scope reticle unfamiliarity
You have what's commonly referred to as the "crossbow reticle". I think it's shown in Wikipedia as a rangefinding reticle overlayed on a tank, or something like that. Since that reticle is normally installed in optics that are not very expensive, i doubt you'll find a subtension schematic anywhere on it though it is common enough. Most guys that have the reticle won't have the slightest idea how to apply it for rangefinding or downrange zeroing, hence the reason for no schematic really.
Honestly you're going to have to measure it. I would anyway. It's not really that hard to do and it will pay dividends down the road if you wanna' use it for RF'ing or DZ'ing. Although it is a screwy looking reticle [obviously designed for rangefinding mostly as it's an inverted tree reticle system like Bushnell's DOA reticle], it can be applied to some degree of accuracy for RF/DZ'ing including windage.
For RF'ing i'd measure it at the optic's highest power, and then you can choose another power if you wish that will give you some even MOA or IPHY value for DZ'ing--calcd. and/or measured [fact is, it may even be able to be used vertically at the milliradian subtension of 3.6 IPHY at some magnification as long as it doesn't exceed 3.6 IPHY at the optic's highest power]. Leastwise that's how i would apply it...but there are many ways to apply SFP multi-stadia reticles for RF/DZ'ing.

Re: scope reticle unfamiliarity
right on steve. Guess i get to go lay some downrange then.
yes it is a 2-3 bill scope, but pricerange is key.
I can make it work, and when the franklins come in I'll step up.
unless someone's got something expensive they want to offload cheap to a good old boy on a budget.

Re: scope reticle unfamiliarity
You don't really need to shoot, or even go to the range if you have 100 yards to work with at home. Just put up a yardstick at 10 and view it in the scope so you can see how much the marks subtend at max and half power. Once that is known, you can match it to your trajectory.

Re: scope reticle unfamiliarity
yep, i've got about 350 yards to play with at about 7 to 15 degrees incline varying. nothing a bit of trajectory math didnt fix, so shooting it aint a worry. right now its boresighted 1-1/2 high at 100.
aint got to poke my own loads yet but I'm just running the constant 147 nato FMJ.
the old scope, i ran 17/20 from cold bore at 300yd with remington 150grains to a 6" steel swinger, and that was before I changed the stock.
Aint fied it on the new platform yet.
hey, you aint got a windage factor constant out to 1000 for the 147 grain nato have you? with that, and a chrono, I can work some algebra and come up with about any parabola I want and graph it with a TI-83 calculator.
