Re: I found a Sightron S3 LRMD

50 MOA hey?

Well let's see... If shooting 6.5x300 wsm, at 3250 fps and at 5000ft of altitude, we
get the following info. using Berger 140 gr. VLD

I found a Sightron S3 LRMD-50moa.jpg

It shows that from a completely horizontal boreline, at 100
yards the bullet drop would be 1.7".

So, a 20 MOA base and zeroed at 100 yards you would have a total of aproximately
41 MOA and 2 clicks of (1/4 moa per click) of vertical adjustment left for long range
shooting.

Looking at a drop table for std conditions at 5000 feet of elevation, it boils down to:

At a 1000 yards you need only 18.3 MOA!

At 1200 Yards you need 24.6 MOA

You will be using up all 41 MOA and 2 clicks at about 1610 yards.

As we all understand, that's possible because of the amazingly high BC. and

a pretty decent muzzle velocity.

Good Hunting!

Nice try Eaglet. How may people are shooting a 6.5x300wsm? You picked quite a hot-rod to prove your point.

How about trying something that someone is more likely to be shooting? My pick would be a 308 with 180g Accubonds at 2600fps.

How's the 223 shooting? I have a 6.5x284 that I just finished that you could try.

Re: I found a Sightron S3 LRMD

Nice try, hey?

Ok! I'm not being quite fair but I'm still playing...

I'll be using a 26" barrel in a 308 Winch. and two bullets...

1...Berger Match Hybrid Target 155 gr. BC7=0.247 ( ) MV = 2950 fps
2...Berger Match Hybrid Target 168 gr. BC7=0.266 () MV = 2850 fps

Elevation 5000 feet at standard conditions.

Elevation MOA adjustments and Energy at 1000 yards.

155 gr. @1000 yards 26.5 MOA 813 ft-lb
168 gr. @1000 yards 27.6 MOA 890 ft-lb
-----------------------------------

155 gr. will have 1000 ft-lb of energy at 860 yd
168 gr. will have 1000 ft-lb of energy at 915 yd

Enough energy for antelope, deer, cow elk, coyotes, etc.
------------------------------

Approximate max. MOA adjustment range will be achieved at the following distances:

155 gr. 1265 yards
168 gr. 1247 yards
-----------------------------------------------
NOTE: these bullets are not suppose to be hunting bullets but......????

The days that we needed 39 to 40 MOA to reach 1000 yards with the 308 Winch.
are far gone and lost in the past.... JMHO

--------------------------------
Sorry to say my 223 has not yet been glass bedded and I'm jealous about your
6.5x284... Have you shot it? Did you do as good looking job as you did on mine?

Re: I found a Sightron S3 LRMD

I see your still avoiding my heavy hunting bullet. This isn't long range shooting....

No, I haven't shot the 6.5 yet. I don't have the dies and I can't afford factory ammo. Besides that, I haven't figured out how to fire it yet, the bolt is on the wrong side.
