How goes the load development?

Ain't TOUCHED IT!!!!   :laffs:  It's so damn hot here, brother.  Haven't played with those 300 A-Tips and the MagPro at all.  Gotta work up a load for 2 months from now, 22 ARC with 85.5 Bergers, for that match that Matt and I are going to near SLC.  I'm shooting 22 ARC for this match tomorrow, factory stuff - and that give me all the brass I need to start working this thing up.  Basically, after tomorrow's match, I have the brass to work something up, test it here in the August match, then take it to SLC in September...

So, planning the scope mounting solution out.  The scope is set, 32 mils of internal travel, advertised, both windage and elevation.  I need to take half that elevation travel out.  I need 16 mils out.  

I have 20 MOA built into the top of the rifle.  I'm putting the Burris Signature rings on it, adjustable to 40 MOA. Math on that:

60 MOA in the mounting on that setup.  60 / 3.4377 = 17.45 mils.  Good.  The scope is advertised at 32 mils internal, but it's probably more than that.  if it's actually 35 mils, I can have a 100-yard zero.  If I don't get a 100-yard zero, I don't care.  I'll take a 500-yard zero, just like the .300 Win Mag has. 

So, speaking in MOA...   20 MOA in the top of the gun, 40 MOA in the rings.  32 mils in the scope x 3.4377 = 110.0064 MOA, so 110 MOA scope travel.   10 mils in the actual reticle itself, measured out in that reticle, just for hold-over if I have to.  that's another 34.377 MOA, or 34 MOA. Total max range that I'd build in would be the equivalent of dialing plus holding...   204-ish MOA...  Or, about 60 mils..   

That would let me dial/hold to 3100 yards.  Dial only to somewhere between 2800 and 2900 yards.  

I'll never get it to 2 miles.  I need @Magwa's Ivey mount...  :lmao:

With the Ivey mount, I could dial only to over 3800, justt short of 3900, and I could dial/hold to a tick over 4000 yards.  Damn...

So what about these cool prisms I see them slapping on that add to the capability?

Charlie Tarac.  Those things are insane...   :hail:

Basically - whatever you have - multiply that by what they say their device will do...  They are all clip-ons or add-ons, and go on the end of the scope, or on the rail in front of the scope.  Or, combine the clip-ons and add-ons for that much more.  Exponentially.
