Setting up for EXTREME Range Shooting

[catnthehatt]

tannerite targets would help a bit. but big bags of flour behind the target will assist in sighting shots

I ws given the chance too shoot some tannerite the other day - WOW!!
Very cool stuff...

A good rifle with equally good ammo on a day with no wind or mirage, will need a 20' target to record MOA hits at 8K's. If the shot is made facing north or south the bullet will drift 8.6" due to rotation of the earth. I have trouble imagining an application for a rifle bullet, even a very large rifle bullet, which on it's best day can only hit a 20 foot target. But it would sure be cool to do it!

 

[JBD]

Might I make a suggestion

Lot's of them lying around in parks.

Signguy, if I could hit the tannerite target, I would have the worlds most accurate rifle. Aren't they just small boxes?

TS, the biggest issue using the 223 is that you will never see where the bullet lands. I think even at a mile, the impacts are going to be pretty small. Add a bit of wind and you will be all over the map. Why I am looking at the 7mm as a min and the 30 as an option.

Just started testing the 180gr Bergers at 200yds and got to 1/2 MOA. Now to tweak and see what I can get. Will have to chronie soon too - a toasty load.

Kevan, now you know why I have not gone down the BMG road. Can't afford it. The 300RUM is already pushing $1.00 per bang let along $7.50. Makes for a pricey afternoon.

LRC, you will need to shim that scope and will likely need to use both a base as well as rings. I think your scope was indexed at 22X for the reticle wasn't it? A nice mag to have. Beyond 2000yds, you WILL have a wide field of view.

With Burris rings and the right base, shim so that the top of that reticle w/ full down is 1000yds/m (likely 25" high at 100yds) or some distance you can easily shoot into. That way center will put you around the 1500yds/mile. I think those scopes have 60 or so min of travel and your reticle should have at least 30min, you can make the trip to 2 miles or well past 2700yds.

You may also want to consider adapting the forend to ride a pedestal rest. The error of firing off a bipod will be enormous once you start pushing the envelope.

tootall, with that line of argument, the 22LR is effective at a mile- cause it says so on the box. I wonder if these experts have even handled a gun???

I bet they are all over the HG issue now.

jason, I was thinking more in line with the Orelikon 20mm cannon with auto adjust, laser rangefinder. If memory serves me right, they are accurate at 3km's and effective out to 5km's or so. With the slugs that puppy is pushing out, you can spot with the naked eye

Fun, fun, fun.

Will have to look at making that base as I already have $20 towards the cost of manf....

Now that's confidence.....

but while I applaud your confidence , I would think there are but a handul of rifleman that can accomplish consistent 2 mile hits, and I am pretty sure they use the big

let us know how it goes though

Been trying to find the club that does this in the Midwest. They shoot 308's to 3500m. Varmint shooters have hit all manner of game at ranges beyond 2000yds. Not sure if they made it but there was a group shooting 300WM's going for a 2 mile gopher.

Not many that do this type of shooting use the BMG simply because of cost. It is by far the best bullet for aerodynamics (750gr Amax) but at around $6 to 10 per bang, R&D is going to get pretty pricey.

I just did a secondary test and it looks like the 7 Mystic will hold 1/2 MOA at 200yds. I was hoping for better but no biggie as the most important thing is to stay consistent way out there.

Got to put on the shimmed bases and sight in for much further out. Testing at 1000m and 1 mile to follow. If that goes well, will work on getting some exotic base built.

Jerry Jerry Jerry.....I respect your advice on many topics but asking me to use a PEDESTAL REST!!!! It's just not the way I tick. Im a hands on kinda shooter. If I can't do it I can't do it, I will go as far as my ability safely allows me. Pedestal rests and vices are for testing loads not riflemen!!

Definately not enough elevation in MOA in that retical to reach out that far. I was thinking a magnification reduction go generate a larger field of view and use the rectical for hold over corrections. I had another option cross my mind last night that might work also. I have a rail block for My AR-15 that raises the scope about 1" that I can mount under my scope and to the existing rail on the BMG. Since all is adjustable on my .50 I may be able to get the elevation I need to reach out. If not just get a rail down the road. Im going to play with that Idea a bit.

Let me get this straight. LRC you have a custom built 50, you KNOW the guy who built it makes the rails for the rifle he builds, RIGHT??
Why not ask him to build you a plus 45MOA rail??
Worked for me. The other option ofcourse is a US Optics SN9, 200 MOA built into the scope, imagine how fatr that would get you???

SN9 is sweet but I'm thinkin that the 45MOA rail would be a tad cheaper.

You know me....never take the easy way out....first I have to humiliate myself before common sence takes over . It is already in my train of thought just havent commited to it as of yet. Got a new pistol to pay off and reloading components to get in order to start building from the lessons I learned in Summerland. It's going to be another happy expensive year.

Better load up that .50 LRC, the river is going out as we sit here!!
Old Badger happened to be going across the bridge and noticed a 4' wave of ice heading downstream!!

Varmint shooters have hit all manner of game at ranges beyond 2000yds. Not sure if they made it but there was a group shooting 300WM's going for a 2 mile gopher.

Jerry

...and i was feeling pretty smug making an 950 yard gopher kill with a 6BR!

I'm thinking there is probably some merit to the notion of a gun carriage-like device with T&E adjustment where you move the barrel, not the scope since you are almost talking indirect fire.... set up an OP to direct fire etc... ...they wouldn't be shooting matches, they'd be "Fire Missions"

 

[Mystic Precision]

Obtunded, a 950yds hit on a pop can is a great shot. As distance stretch beyond 1000yds, hitting really small targets drops off. Afterall MOA at 1 mile, is 18". Just a tad bit bigger then a gopher. With wind, keeping MOA at that range is unlikely so it becomes more 'luck' then called. As you say, directed fire.

This project is not to try and connect on anything that small. There are boulders roughly 4 to 6' across at the 'mile' mark that will be the targets when I try going beyond 2000yds. From the new extreme range hilltop, those mile rocks will be between 2500 and 3000m. The terrain will kick up a good amount of dust too so seeing impacts is plausible.

If nothing else, it will give me a graphic idea of what a few bullets do when they go subsonic. Will they be stable? How will their trajectories change? Is wind drift linear?

The rifles, cartridges and bullets available today really make shooting sub MOA at 1000yds/m a fairly simple process. Except for wind doping, they have shot very well at all distances on this side of supersonic flight. Now to see what is on the other side and to reach out further then last time.

Jerry im so jealous of you little piece of paradise!

Sounds like a fun project...youll be able to take a sip of coffee after you shoot, and then spot the impact.

mike, sort of like blackpowder shooting. Bang, tick, tick, tick, splat. Estimated time of flight to 2 miles is 6/7 secs.

Chronied the 7 Mystic today. Was very pleased with the 2845fps velocity. Exactly where I was hoping and right there with the short magnums which this case mimics.

Found that I had put the wrong shims in the Burris rings...ooops. Didn't get a chance to shoot at 200yds but assume groups would likely improve a smidge.

The scope is now shimmed for 18" high at 100yds which should put it around a 700/800yds zero. Might need to shim higher if I run out of elevation before the mile. Will be close.

Using a two piece Farrel 20MOA base and the Burris rings. A very nice compact setup.

Sounds like my Barr and Stroud is going to have to make the trip to Summerland next year with LRC to range those things for you.

Thanks Cat but I already have a WILD rangefinder.

Works very well at extreme ranges.

The reported accuracy is a few percent error out to 5km, then around 5% out to 20km.

Fire for Effect!!!!!

[oldbadger]

Just ruminating, why tilt the scope? Why not go ala optical rangefinder and fit a tilting prism with a micrometer adjustment? Clamp onto objective end of existing scope and viola! I hear violins!
