Hello everyone,

I am looking to put a 3-9X40 VX2 with the LR Duplex on a .257 weatherby of mine. Do these reticles really work, and work well?? If they aren't worth it...tell me about a M1 turrett.

I have never used either, th M1, or the LR duplex, so stay with me here..How does the M1 work?? Zero it, crank it to the yardage, and send it flying?

Thanks for your help,

MK

I have Leupold 6x42's with the LR Duplex on both a .270 and a .340. Although I haven't tried them past 400 yards so far, both are right on up to that range when sighted according to the directions. In a variable, the dots are "on" for range only at the highest power.

I like the LR Duplex and it is very fast and effective in the field. You can't spin it the wrong way by mistake, either.

WHB,

Being that it's a .257 weatherby, I looked at the charts, and it seemed to be suggesting to have a zero of 300 yards...I am not sure if I like that so much. Am I reading that right? 100 tsx at 3650+ with a 27"

Yes, the highest velocity big game loads are supposed to be sighted for 300, which would give you a mid range rise of less than 4 inches. You should not be too high for a good hit within 300 yards. The dots will then take you out to 600 yards, as opposed to 500 with the "slower" rounds like a .270 that are sighted at 200.

If you prefer a 200 yard zero with your rifle, you can do so, but then you will have to experiment to see where the dots put you...they might be on at 50 yards less than they would with a 300 yard zero, but you will have to do some range work to know exactly where they are "on".

If I had full time oppertunity to experiment as to where the dots hit, I would run one. Unfortunately, the range I use 90 percent of the time only goes to 200 yards.

I've got a cheap vx1 4x12 lr on top of a tack driving winchester 70 sporter 25 06 and I took it out to the range the other day and the dots were right on at 300 400 and I hit the 550 yard gong with it too

at a local prairie dog town I hit a 450 yard prairie dog with the 1st shot with the same rig

so as far as i'm concerned i've got a 500 yard antelope / deer rifle and yes the dots work for me

MK,

I've run the LR and just recently helped a neighbor obtain one, the very same 3-9x40 you mention. I feel you need to chrono your load, or at least know the factory velocity as well as the bullets BC. Then run it through a ballistic program ( such as JBM online) so you know your bullets drop in MOA. Then, look at either the booklet that comes with the scope or the online booklet ( http://www2.leupold.com/resources/downloads/2008_03_BAS_Engl.pdf ) and see what the drops are for the 1st, 2nd dots and top of the bottom picket. That will give you the distance at which the dots and picket match up to your bullets drop. For you, it will be on page 7 of the booklet.

For your scope at 9x the 1st dot will be a 2.19 MOA drop. 2nd dot at 4.8 MOA and 7.82 MOA drop for the top of the bottom picket.

I've used the 6X and the 2-7 with the LR reticle.On my 7 mag (with a 300 yard zero),I impact slightly high at 400,500,and 600;not enough to miss anything though.The 175 Partition at 3075 is "on" at those distances.

MK with that 257 Weatherby load a 300 yard zero is very easy,with negligible mid range....you would, however have to shoot it at longer distances to have any idea where it hits beyond 200 yards.

I have it in a 6x36. I like the concept, but past around 400 yds the dotz are too big to be really optimal for me on a deerish size target.

Thats ok for me.. The scope is on a 300WSM and elk is really what I had in mind so the dots get me to as far as I would shoot at an animal.

If I could change it.. I wish they were little ticks like Burris uses.

I like to calculate the +/- 3" ranges for each dot and then shoot to confirm.
I think these were some numbers for my 250 savage and a Burris.. but the concept remains the same. If you do +/- 4" the range windows are a lot bigger ( as they would be for something a lot faster than a 250like your 257)

cross hair 0-250
1st Tick 210-300
2nd tick 340-390
3rd tick 440-480

I look at the LR duplex system as something that is not precise enough for LR shooting.

First you have to use the correct magnification (in your case 9X) or the stadia spacing changes. On occasions poor lighting will make it hard or impossible to see the animal on max magnification. I will concede that 9X may not be high enough to matter.

Secondly the stadia are precise for one particular yardage. The time you use studying where to aim for the inbetween distances could be used to twist a turret to the exact point of impact.

Seeing you are using a 257 Roy, 2.5"-3" high at 100 yds covers you out to approx 350-450 yds without much thought. If the animal is past those distances there is usually time to twist a turret. I'd rather aim at center of mass at longer distances on any magnification I choose.

Either way you will have to do some shooting at longer distances. JBM ballistics program with proper BC will work well. I usually shoot at two known distances, 300M and 500M to establish the turret comeups being accurate. The LR duplex will require shooting all stadia to verify. An earlier poster gave you the MOA spacing for your scope and when combined with a good ballistics program should get you close but you will still have to shoot the distances to verify.

I know there are many here that like the LR stadia system. Your choice.

Hope you have a successful hunt this year.
