The B&C reticule is first hash 2.2 drop,second4.8,third 6.3, post 7.8 moa. Ilike a 200 zero. Figures are on large delta. Calc a 200 zero and see what drops match reticule. There is a program to do this also, some scope companys have there own on web site.You then STILL have to field verify, doesnt matter what scope.Notice you are in G Falls, I would think someone at Scheels in gun dept. would be up on this, they sell rifles with test targets that shoot itty bitty groups.I also use the last hash as a dial off point, which is a 500 hold for my 257.Example I dial 2.6 moa on cds turret for a 600 yrd. shot
Well, not sure what you mean by long range techniques. Using an old Burris Signature Scope to test with, a very sturdy lead sled, 200gr Accubonds were chronoghraphed.... light loads only pushing 2992fps....rounds were tested out to the 600 yard range holding zero on center dot everytime on 8' high home made ply wood. Measured out drop in inches from zeroed 200 yards. Shot 2 shot groups at each yardage holding zero wating 5 min between groups to cool down. Zero wind.

200 yards.....0.0
250 yards.....2.5" drop
300 yards.... 6.8" drop
350 yards.....12.2" drop
400 yards.....18.4" drop
450 yards.....27.0" drop
500 yards.....37.0" drop
550 yards.....49.2" drop
600 yards.....61.2" drop

Leupold VX3 B&C was then planted on RUM. Using Leupolds guide, we matched the bullet drop, speed, and weight to the correct "group" chart that came with scope. Scope was then zero'd at 200 yards. Testing began. 300 yards was 2" low. Too much for my likings. 400 yards was over 4" low. HUH??? My rounds shot high in inches compared to their "Leupold" chart during the Burris testing. How in the heck was it low? 450 yards was 6" high. HuH again? One extreme to the other. Should have been dead on or slighly high. Not 6" high. 500 yards was 8" low. How. I should have actually been slightly high on most. Tried to get it to work over and over. Just didn't happen. Called Leupold. They said it was just to get you close.....kind of a refrence. Scope just didn't work for me.

Also, looking for a scope out to 1000 yards.

Re: Going Scope Crazy!!! ....err

The reticule is marked at there selected numbers, if you get another type, you have to do similar process, or just dial the drop.Their reticle. first hash 2.2 is exact match for drop you gave. 6.8" divide by 3 for the 300 yard =2.2 moa.Next hash is 4.8 moa, your drop at 400 was 4.6 moa, which is close,but high, next hash is 6.3 moa your 500 drop was 7.4 moa low, it is about matching drops to what is preset in reticule to use as hold over. Changes for every load and reticule type. IF you use a mil type for hold you have to match drops to reticule.You are never going to get reticules to be set for 2,3,4,500 etc. unless you are lucky and they match, or go with a custom dot type. That is why so many dial.When I printed a sample ballistic chart off your info,I came up with close numbers200,325,425,490,post was 45.2"drop and 7.8 moa.There is a program that will solve reticule drops, I dont have it.I have many different reticules over the years, and I like them for quick holds, like varmits. Burris sends a bunch of sticker with thiers, but you still have to find the closest. I know the drops on my mil ret. and they are odd #'s like 275,350,412,475,... out to825 for 5 mil hold over, but for precision ltr I like to dial. Notice that you have archery freak. IT is kind of like using fixed pins vrs a micrometer type site. I have seen guys with fixed pins set at odd #'s also. What reticule did you go with,type for your varmit?

Makes more since. Thanks for help. I guess I was under the impression that if my bullet weight, speed, etc... matched their charts, it would have been right on. Little misunderstanding on my part. As far as the reticals for the varmint scope, I'm really liking the plain DOT retical. Very fine hairs with the single dot. Seem extremely easy for me to dial in on a prairie dog or a Yote. Like the idea of turrets and the dot......simplicity works well for me when varmiting.

Re: Going Scope Crazy!!! ....err

I've seen the same thing with Leup's Varmint Hunters reticle.

First off, they don't advertise what the subtension (spacing) between marks really truly is on all models/powers.

Hell, I even called customer service and requested this info (on a specific model at max power) before I bought a $1700 VX-7 with said reticle........I got "it's a relative thing, dial the power to match your real drops" response..............Umh?

Well, that's ok (I said to self), bought the scope anyway and first thing; set up a target with inch grids at exactly 100 yds, and veiwed through max power (14 on this model)

I quickly determined that spacing between lines was:

Main crosshair and Line 1 = approx. 1.8 IPHY
Main to Line 2 = approx 4.5 IPHY
Main to Line 3 = approx 7.5 IPHY
Main to Line 4 + approx 10 IPHY

I did windage marks too, but that's a different story.

Theoretically, that reticle (on 14X) will work for at least 3 different rifles I have, based on ballistic reticle analysis on NF program when sighted in at approx 300 yds (real life drops are very close out to about 600 yds).

I guess my point is, the guys that designed this reticle know way more about shooting than the people that answer the phone or print the diagrams at Leupold..........Still, so far I am very happy with the scope, but I dont believe I would've ever had this issue with some other brands.

IMO, Leupold is behind the times on their BDC reticles just as they are on offering a MOA or IPHY reticle (which Nightforce and others have had for many years)..............But, the Customer Care package on VX7's is pretty cool, and they are made in America and stand up to their warranty.

Pick our battles I guess?

Re: Going Scope Crazy!!! ....err

I use one of the VX-7s on my 06AI, I have been impressed by it. I am a gimmick type guy and love the pop up scope caps on the elevation and windage. I do not shoot that rifle much anymore but seem to recall that even the side focus had those same caps, which I did not like. What a pain just to adjust parralax. I probably would not buy another even though I like mine. For the same money leica has a scope that I would prefer. I am gonna pick one up next week with the low turrets and .5 mil reticule. I gotta run by the walmart and buy the cheapest junk scope I can to get the 500 dollar off price deal which ends this month.

Yes, I could do without the speedial cap on the left side. I really do like them on the windage and elevation however. Lost count over the years of how many scopes (with target or tactical knobs) get accidentally turned, or turned the wrong direction on hunting scopes. Especially when sliding them in and out of scabbards, seats of pickups, gun cases, somebody else handling the gun, ect.

Holy Crimony, my son and my best friend are both probably a finger turrets worst enemy.....seen em both FUBAR a scopes adjustments in seconds. Needless to say, the Speedial was the #1 selling feature for me, LoL
