dasher 1000 MOA

[boiler_house7]

I know theres several variable to take into account, but I took my dasher out to a private range with a 1000 target for the 1st time. It is supposed to be correct, but my ballestic programs not matching up to good with my 700 off more than a 1 MOA. My load shows 3080 at 70 deg 3000 ft 10% humidty, no wind and zero is 100. conditions shooting at 1000 where 60 deg 3 mph wind left to right and 20% humidity. I ended up with 23.8 MOA up and 2.1 MOA Left. Hitting good. Does this sound in the ball park for a 1000. sure like this dasher. Thanks Bill

yah you are in the ball park!

yep. might actually need a little more depending on the bullet BC, but you are in the ball park

Scope ring heights make allot of difference. The higher you go the more adjustment is needed.

Not according to the Sierra Infinity program.
With all other parameters being equal, and a 100 yard zero

scope height 1.5" needs 25.3 MOA to 1000
scope height of 2.5 needs 24.4 MOA to 1000.

The higher the rings the LESS you need to come up.

Sight height and elevation needed are inversely related at long range. Only at close distances, such as 10,20,30 yards will you need more elevation the taller your sight height.

When a scope is mounted closer to the bore it take less min of adjustment to raise the barrel.From the time a bullet leave the barrel it is dropping. Their chart will show that.Just a example low mount zero at 100yd 1/2 ''high at 135yd back on at 155 yd Hi mount zero at 100yd back on at 225yd It the arc the bullet passes rising and fall through the line of sight.

Savage dasher, I'm not sure what you are trying to say in your above post, but what 4xforfun and I said is correct. At longer ranges, like the 1000 yard example that the original poster asked about, the taller the scope is mounted, the less elevation will need to be dialed into the scope. Your first statement of "Scope ring heights make allot of difference. The higher you go the more adjustment is needed." is exactly backwards at longer ranges.

my scope height is 1.670. did not realize that made that much of a difference. Thanks

It doesn't. In the equation I sighted (1.5 vs 2.5 in. ring height) the difference is HUGE....I mean the difference between 1.5 and 2.5 inches is a very large percentage. If you could guess within a 1/4 inch scope height, which is very easy to do, by the way, then the MOA difference is a moot point if you are wrong or off a little .The only reason I mentioned it was because he had the outcome wrong.

I zero at 300 as my starting point with all of my scopes. When I do this , scope height becomes an even smaller issue.....like .2 MOA difference between 1.5" and 2.5" at 1000 yards.

My point.....don't sweat the small stuff!!!
