This scope is great, I have been spotting my own hits at 2500 plus in most cases. It is unbelievable how much the extra 3x brings to the table over the NXS 22X.

I think I have about 126 moa of dialable elevation. That should get me close to 3K for a center reticule hold.

Excellent!!! Now I have to decide if I want to go with a set of Ivey rings or step up to a scope with higher adjustment range. The ATACR seems to be about the best option out there. I like the Vortex Razor as it has even a bit more adjustment range then the ATACR but wish it had a bit more optical power. 20X is a bit lacking at extreme range for spotting shots.

Throwing a set of Ivey rings on with 150 moa of adjustment range along with a 40 moa rail and a scope with 105 moa of vertical adjustment would certainly reach out a fair ways!!

Anyway, thanks for the information on your set up, very helpful to all of us I am sure.

How has the wind been treating you. Hopefully nothing like up here. Since the first day of fall, we have had a grand total of one day that the wind speed was under 18 mph and 5 days that its been over 50 mph sustained winds. Makes it a bit tricky to get any rifles set up with any real degree of confidence.

Re: LRKM to almost 3K

This is impressive for sure.
And makes it even harder for me to wait for my new barrel in my 338LM, which now will be 338LM Imp.

If it is ok, I would like to share a video that I did yesterday. I managed to set up my camera, and film when I shot at 2135 yards with my 338LM. Used 300 grs Scenar, and some 300 SMK's, pushed by 96 grs of Viht N570.
Mv is 2929, and ES is on the single digit. The barrel has 4300 rounds through it, and Coal has grown from 3.7 inches to 3.94 inches. Throat is very burnt out, and somehow I now can use 96 grs of 570, instead of 92 grs, which was max in my rifle when it was new.

There was a lot of wind, you can see the trees moving. I shot under 1 moa, and the last 4 shots are SMK, hitting a bit lower than the Scenar.

It's been ok. I was up and out early this am confirming drops on two rifles. A 6.5x284 and the LRKM. The 6.5 was easy as we only shoot it to 1000. I have the LRKM confirmed to be spot on to 1300 plus and a few cold bore hits at 1500 and 1760. But want to do a bit more confirming on the longer distances. The wind picked up and I came home. Suppose to blow from the west this afternoon with 25 mph gusts but diminish over night and tomorrow. I shot have spot on data to 2K by the weekend. The program id doing very well and getting along with the final velocity of 3210. I picked up an average of 12 fps with fully fire formed and sized brass. I was expecting a drop with temps in the 40's instead of 80's. But not the case. I guess 570 is pretty stable. I am confirming that too with test rounds at different temps letting the rifle cool to ambient temps for 30 minutes. This can all be adjusted in the program, but the less temp sensitive the better in the long run.

Lots of work and time goes into all this if you want cold bore hits at a mile plus.

Kirby I use the ATACR, as Jeff says the difference in glass & the extra 3x top end power over the NSX are noticable.

I use a 20.7moa SPUHR mount & a shimmed 30moa rail which gives me 2.5 moa down & 130 moa up + the reticle, with a 100 yard zero, this will get me out past 3000 with my 375.

Re: LRKM to almost 3K

Yup! Come on Kirby, reach into that hot rod budget and spring for an ATACR. I have set up 3 and all were great. There are more in my future when I recover from all the stuff I been buying. Plus I better leave a little for the taxidermist this year...

Ya, I have four heads coming due at my taxidermist as well!!! Can't cross the hotrod fund and gun fund or there is mass chaos!!!

Re: LRKM to almost 3K

As I work to get confirmed hits and dialed in accuracy for cold bore I am learning a few things. This morning I went out to shoot at a vertical faced rock I have a kill zone circle painted on (10 to 12") I got to my shooting location at 1660 yards ready for my cold bore shot. As I got out of the truck the wind was full value and brisk at a 6 to 8 mph favoring 8. I thought to myself that I would not be getting any solid data for cold bore at close to a mile in these conditions. I elected to wait for better conditions. As I started to drive off I thought, what the heck, I am here. I set up solid as I could get, dialed in 6 moa left and 38.25 moa up for the 1660 yards cold bore poke. Now with all the 338 shooting I have done in the past I must tell you that I didn't have a lot of faith with this wind and shooting up and across a canyon. I sent the round and to my surprise I was just on the outer edge of the kill zone circle. wow! I dialed another 1/2 moa for wind and put two in the circle and one high on the top edge.

What I am learning here is this. A big high BC bullet is your friend if you can push it to good levels of velocity. This rifle and it's velocity has made me much more successful for cold bore hits. I use to favor rifles that were a little slower and had more barrel life. I can always just dial a bit more, right? But witnessing what the velocity is doing for me has changed that mind set. Higher velocity rifles are much easier to shoot and will give you a smile more often. I don't think shooting slower rifles hurt my skill set a bit, in fact it made me be very careful with my wind calls. But now if I am a MPH or so off it is much less of an issue. The drifts are simply smaller.
