2000 Yard Match With Flatbase Bullets

[LynnJr]

Shooters
We held a match Sunday with a pair of 300 win mags a 338 Lapua and a 300 wsm at 2054 yards.
ALL shooters hit the gong!!!!
The weak link is as always the scope bases not having enough elevation.
I was using a 300 wsm and using a BIB 187 gr flatbased bullet and Adam and myself both connected with gong. I ran out of windage so we were forced to aim at a bush about 7 feet to the right of the gong to connect with it.

As some might remember this was a make up match due to truck troubles and the truck trouble solved itself when the connecting rods left the block and oil pan.

I made the match in a U-Haul loaded down with gear. I forgot all about needing 4 wheel drive until I got to the road were the gongs get hung. If you never got to shovel rock for 4.5 hours in 85 degree heat with a blown rotator cuff all I can say is I was madder than the piano player in a marching band. After I shoveled my way in I had to trim brush so it wouldn't scratch the U-Haul which made me madder than a midget with a yo yo. Got to bed at 11:30 Saturday night and up at 5:30 to hang the gong and meet up at the rallying point.

The old bones were sore but the new engine should be here in 3 days.
Was it all worth it without a doubt yes! Met some great shooters and had a blast. I can't vouch for everyone but I put 100 rounds downrange and by qualifying time one Shooter only had 10 shots left. I think every Shooter shot at least 75 rounds.
Check out the pictures.
And a huge thank you to all the shooters for turning this bad beat weekend into fun.

Flat base??????

Show off!!!!

Love your write up... solved itself when the con rods left the block and the oil pan.........

Hope you're feeling alright after that workout.

Lynn, that was a blast. Watch out for the bush monster behind the gong! He eats your shot and aint even got the common courtesy to tell you where your shot was.

When we first started shooting I had swapped scopes on my 300 wsm and with the 300 moa base you need to mill out a 3/8 section. I cut off one of the crossbars on my picatinny rail but I didn't drill down.
I calculated 121 moa needed but without removing the entire base I was going up in 5 moa steps which took 25 shots to set the lights off.
On the match itself nobody hit 3 out of 10 by the time we went for record and nobody but myself had enough ammo to go for a second qualifying session. It was actually a good day but it definitely got hot.

I will post a picture of the bullet. On Doppler radar it runs 0.525 bc and out of a 32 inch Krieger 13.25 twist I am only pushing it 3050 fps.
What makes it so fun to shoot is the load only has mid single digit extreme spreads. Once I set my elevation and locked down the base the only adjustment was horizontal.
The picture is horrible but the bullet is one of the most accurate 30 cal bullets money can buy. It has a pressure ring on it unlike factory flatbased bullets but it still shoots to 2054 head on.

When I picked up the gong I removed some more but I needed a shower and some sleep.
It isn't the best location but it is real snipery.

What, no Mamba to help you out this time??

Lynn, how do you like the MOAB150/MOAB300? I bought my wife's new car last week and tomorrow I have to pick up a new radiator for my truck. Then I can order one for me when I get the cash. Trying to decide between the MOAB and the Ivey rings.

The MOAB 150 and 300 are identical except the 300 has a longer bolt for adjustment range.
When you lower a 150 to zero it is completely smooth on the bottom. When you lower a 300 to zero there is a very fine threaded bolt sticking down about a quarter inch. So you mount your scope in the rings and slide the 150 into place and install 3 crossbolts to secure it.
On the 300 you need to drill a 3/8 inch relief hole in your existing base to allow for more travel.
With your 50 you are good to about 4100 yards.
The mount has a pivot bolt on the front that needs to be loosened before making large adjustments then retightened down. If you don't tighten the front pivot bolt you get about 1 moa of slop at 2000 yards.
I will take some pictures for you to look at.
There were shooters there with a 70 moa base but it costs more and doesn't give you much range. When you go from 2000 yards to 2500 yards you need a large amount of elevation for only 500 yards more.

Lots of people talk the talk. Way to put together an event where guys can go out and actually do some walking! Rarely are people willing to put the blood sweat and tears into the management and curation of these sorts of events, and without them everyone just sits at home and shoots from a keyboard.

Very well done, and great respect to you.

I have a mill and lathe. I planned on the MOAB300 as I want to be able to get a dead on at 100 yards (USI) as well as at 1,000 yards (FCSA matches) as well as at 2,000+ yards (URSA matches). I just worry about how accurate it is and how it will hold up to the recoil. I figured I would mill the base on my Sendero so I can try it with a 7mm Rem Mag too. Do you torque the pivot screw each time?

...I ran out of windage so we were forced to aim at a bush about 7 feet to the right of the gong to connect with it...

Nightforce? Did you run out of both dial windage and past the last dot on the reticle? Is that because you were at the end of elevation?

Lynn, I called and talked to US Optics. They said I should have had almost 30 MILS up from my 300 yard zero. They apologized and wanted me to ship it back to them and they will adjust it for free. US Optics has been great about any warranty.

I like that, "snipery". That's one of those Tacticool adjectives, huh?

The 300 will go from a 100 yard zero to 4100 yards with a 800 grain bullet and 235 grains of powder so a moderate load not a barrel burner.
If you only want to shoot to 2500 yards the 150 saves you one step on the 50 but if you shoot a 7 mm go 300 as there is no price difference.
I have company here and will post pictures after she leaves

I was running a 12-42 and didn't realize I was topped out. These targets are fixed distance so I will center the scope and add the elevation to the base. It's just a twist on a wheel but in the heat of competition I didn't pay attention to it.
These are very relaxed matches
On the windage yes with the elevation turret dialed wrong I cut my own throat.
I really wasn't planning on shooting the 300 wsm other than for giggles but after the truck disaster I was down to three rifles.
