I have a 12x42 SWFA mounted on my 250AI tube gun, going out west this summer to camp, shoot and fish with the wife. Setting up the tube gun for rockchucks, and developed a load using Sierra 90gr, tipped blitz bullets at 3200fps. Rifle is zeroed at 200. I have the dials set and shot to 700. Looking at the dials a few days ago, I discovered that the riticule and dials matched within .2 mils out to 600 yrds. So I set the dial at 400. Now I could hold both over and under using the milquad. I shot to conferm this yesterday. Altho I`ve used both mil dots and the quad for quick reference, I`ve never had a load that matched this closly befor at ranges to 600 with minamal adjustment on my part. Very easy...on larger targets like deer, and with a proper bullet, it would be great.
Anyone else doing this???with what, and what load?
Thanks

CG, that system did not work for me. Here is my problem, with chucks, you are usually shooting up or down hill, really throws a monkey wrench into the system. So, knob twisting worked better for me...puts me closer on my guessing with the wind, up hill angle, etc. If you have the whole chuck to shoot at, it would be very different, but more often than not, you have a head and shoulders as a target.

We would dial in the yardage, estimate the wind value(adjust with our best guess), then fire on the chuck. Amazing how close you can get on first shot, we call our shots, not shoot center of mass.

Good luck!

You`re right...as I mentioned, very good for larger targets, but one dosen`t always have a load that exactly matches the reticule.
I do the same as you, and will again this trip, work the dials.
We used to have many woodchucks here when I was a kid..but almost all the small family dairy farms are gone.
Cut my teeth on them with my first .22, long range was about 150 yrds..if I estimated correctly!

What am I missing here? You have a mil reticle and mil turrets, and seem to be suprised that they match each other... They are supposed to, that's the whole point of a mil/mil scope. There is some error of course, but hopefully very little. The load has nothing to do with it.

I believe what he meant is the reticle markings happen to closely match the trajectory compensation he would have dialed if using the dials.

Correct Mathman, my bad explanation. I`ve got some 100 grainers I`m going to play with running hypothetical loads and see what I can come up with.

Well, I`ve got 5 more options with the 250 AI to work with, just by juggeling velocitys.
I`m looking at the 7 Mags next.

Well, just got back from Wy. last nite after two weeks camping and generally lazing about with the wife.
Used the 250AI on PD`s, mostly cause there were so many to be found. With the primary reticule set to 400, I used the scale in the glass with very good success out to about 450 yrds., if you want to say 50-60% first round hits good, but those targets are darned small!
As Keith mentioned, I did have better luck dialing.
With practice tho, for range variations out to 400, deer sized game would be very doable.

Had fun!
