John-that's here in CO where i live.
John, the coffee cup was at 225 and can was 300.
I'm not sure what the subtension of that reticle's axis is at 2x, but interestingly it's actually quite fine, although thinking i could quarter that coffee cup at 225 yds. is a little pushing it, no doubt. Did u see the groups i was shooting with it at 150 yds. Heck they were all over the place, but then when i shot at 225 it seemed to be somwhat tighter. All 3 of those shots landed within 2ft of the tgt. It would be interesting to see what the actual group size is at that range. John set a McDonald's coffe cup up at 120 yds. against a light brown background and see if u can see it with your naked eye. Bet you can. That'd be the equivalent of a 2x at 225.
The important part of those Mk III videos is that a system of reference was established for those ranges that worked well. It wasn't really about what i was able to do on those LUCKY 1st shots. But the fact that 3-1st shots were made because a system was applied just drives the point home that the systems approach does work even with a funky Barska that has 90 MOA of useable adjustment just cryin' out to be researched. Turned out the turret was repeatable in that little Barska, and i learned that a finger-adjustable turret can be used for an improvised tgt. turret system, and is actually resettable.
The 300-yd. coke can was gonna be the real challenge, but it was easy to put the reticle's axis on it cause it was reflecting the sun perfectly, so i had a very defined aiming point. When we shot at 425, my buddy hit a basketball-size bush on the 1st shot and then we at least got close about 40% of the time, and THE BALLISTIC PROGRAM'S CALCS. WERE TRUE!! After we shot at 425 we cranked that Barska down to 25 MOA and shot a little bush at 200, then back to zero at 50, and it was perfect. So a regular optic can be applied as a long-range system even at a cheap 2x.
Oh yeah i ran that rig across the chronograph couple days ago for 1 shot and it was very close to the "generic 22 RF ballistics profile" at 1190 mv. (i used .1 BC at 1200).
One things' for sure John--bet you'll never look at a McDonald's coffee cup in the same light as you did before this thread, ehhh?...ha!
