Just got in from checking out the extreme range launch site for this weekend. Decided to see if my 6.5 Mystic/139gr Lapua Scenar load would make the trip. The 6.5 Mystic is my version of the 260AI.

Had a chance to shoot it out to a GPS measured 2210m/2415yds. Despite the wind, it was very driveable. Way easier then the 223 at a 1500yds to a mile.

At 2090m/2285yds, it was surprisingly accurate. Winds were gusting up to 8mph (got a wind meter now:D) sideways and who knows what head and tail wind. So it got bounced around but not as badly as I was expecting. Could track it easily within a scope view and adj using mil dot reticle.

If the winds held constant, you could drop them into the target area quite easily. I did hit a rock that measures 20" X 20" a few times at this distance but there were alot more misses.

Not sure what the accuracy of a Garmin GPS is but assume that it is within 10m of actual. Got to dig out my WILD and compare.

I always thought that a 7mm would be a min to go these distances or at least a larger case. Apparently not. The 139gr are leaving at 2900fps and should go subsonic around 1550yds - 8 twist Gaillard pipe.

Makes for a less expensive extreme range plinker. The scope adj tasks were aided by a new adj scope base I have just put together. Second time out so lots of fiddling around to do but it does seem to work and hold zero.

Just need some calm air to really see what this rig can do.

Enjoy....

looks like a new stock for the Mystic since the 6mmBR article. very nice indeed. you have grass. I have snow and mud :(. It will be a while before shooting this season. :rolleyes:

Wow that scope is on quite an angle! :eek: Looks good though, it is nice to know that the cheaper calibers to shoot can and will go extreme long range.

The scope was canted for 1mile. I used full up which is double this cant. Should have taken a pic but was having too much fun lobbing lead into that pasture.

BSP, this is the 'sunny' side of the valley. If you look at the hill behind the target hit, all those light coloured spots are patches of snow.

It has been snowing off and on for the last two weeks. However, daytime highs are enough to keep the snow for staying more then a few minutes.

Almost dry too. No where near as dusty as it was last year. Good for the water shed, not so good for spotting hits.

No complaints. An absolute hoot.

Like the new paint job. Same stock but got repainted and the comb chopped off. Will have to build a better cheek piece later as this one is a smidge small.

Good enough for now...

wow that is LONG range when you say WILD do you meana wild total station? I was going to survey in a range on our family farm, and just plant fence posts at the shooting points at 100 for sighting then every 100 from 300 to 1000 or 1200 (that is a long ways for me)
 
WILD is a Swiss made optical range finder. Used by the military for artillery ranging.

Looks like a bazooka with lenses on each end. Can range quite well out to 20km.

Inside 3-5km, the accuracy is excellent.

Using the GPS is a lot simpler but not sure what the accuracy is. Close enough I guess.

Now that's what I call a LONG RANGE, I envy you (in a good way :wave:) wow

In Dumbtario the longest range is DND 1000 yards, but what you got is like out of a movie :eek:

The rig is top notch as usual :D

Your GPS will give you significantly better than 10 meters if you do some averaging. In your case, what you are doing is a differential distance measurement which is much more accurate than a basic location determination.

The newer GPS will also tell you how accurate the location determination is and a lot depends on the number of satelites available, their signal strenght, etc. An accuracy of close to 1 meter is possible under ideal conditions.

I presume that you are quite familiar with the various techniques used with a GPS but just in case, what I would do is "Mark" the spot where your gun is and then use the GPS feature to find the distance to the Marked Spot without moving the GPS. You will get varying distances but if you average them and if it is close to zero, this will give you your first point.

You then go to your target and select the feature to measure your distance to the first marked position (at your gun). You then note the varying distance - will vary and if you take the average of these readings, this will be the average distance to your gun.

Good luck!

PS. I still have your black 6.5 Mystic rifle with the P17 action - haven't shot it but one day I will.
 
Duke1, thanks for the info. My experience with a GPS is quite elementary.

Today, I did have strong sat signals as I was on the top of a hill with great view of the horizon. The GPS indicated that I was within 5m accuracy - might have fluctuated better. I have seen it as good as 1m

I said 10m error because I did a worse case error for the target and bench. 5m error times 2.

Still 10m (if it is that????) is very good. The WILD suggests a 2% error (40m or more) so that is way more then 10m.

With the winds, it had the effect of many times that. A headwind would drop you many yds short. Then it would calm and you were right on. A tailwind gust and you were over the top.

Very challenging. Better wind flags would have been nice. At least I had some.

Part of the fun.

I hope you get a chance to shoot that 6.5 Mystic. It was quite a capable rifle and should prove to be alot of fun.

More shooting tomorrow to confirm my drops and also to test the base for repeatability.

I can see that I will have to mount a scope with more elevation because going beyond 2500yds is a definite possibility.

Rough estimate but it is eating up 14mins per 100yds of travel. How's that for dropping like a stone?

lol a 1.5 mill or 2 mill base lol thats insane

it looks nice you should up date your 6mmbr page for it now which i think you can do

I agree: once you've settled in at these ranges, get some nice pics and do up a long-long-long range article for 6mmBR. I look forward to it. Seems like they are perpetually stuck on Week 84.
 
A little late in posting an update from the Summerland Shoot but this combo is such a hoot.

With my new mechanical scope base, I was able to gain enough elevation to reach out to 2.2km (2400yds). Hope to get somemore elevation as I have a max distance of around 2700yds.

Conditions were gusty and variable but not overly strong.

The bullet tracked wonderfully if you got the read right and the impacts were easily visible (much easier then the 80gr Amax I have been slinging).

At 2km (2200yds), the conditions were quite steady and dropping bullets in and around the target was straight forward.

At 2.2km, things were much more bumpy and tough to dope. Then I also got some large vertical which I am blaming on the wiggle in my bench. Will get back once the weather improves and shoot prone.

Here is a pic of the rig with the base cranked. Kind of funny looking through a 'level' scope with the barrel pointing way up. The stock cheek piece had to be raised about 1".

Given the distance, it certainly kept up with the big boomers. I was pleasantly surprised and impressed.

With the block, I can shoot ALOT before things get hot and that shooting will not put me in the poor house. Loving it...

The barrel is not in the way. I have a clear field of view.

A longer pipe or more up and I would start to 'stare down the barrel'..

But right now, it's working just fine. Rough estimate of up is 140min. It is not linear so at the top of the travel, you move the base more for less change in elevation. The orig mechanical movement suggested 175 to 185mins of up but that has not worked out in real world shooting.

I am sure there is a math/geometrical reason for this but I can't be bothered at this point.

I will machine more adj into the base. I hope to get another 20 to 40mins of up so I can take my 6.5 over 2500yds. Maybe even out to 2700/3000yds. A scope with more elevation adj would solve this problem easily.

Like the 223, beyond 2500yds, a gopher fart is going to push the bullet around. But it is a great challenge to figure that out.
