i used a 6ft long piece of construction styrofoam board(tyvek) to do a similar test ona super sniper / m1a combo. made my target point of aim near the bottom, put a 1" pastie every 10.5''up from their along a straight line i added for leveling. leveled the target at 100yds(checked w LRF) ran the test by firing 1 round, adding 10 moa, firig another all the way up and down 50moa. i was amazed, the SS worked perfectly, w the every shot hitting close to the cooresponding pastie, and the first and last shots 1/2'' apart. didnt check the windage, but 9it was a fun exercise, and showed me how well the scope worked.

Desert Fox,

Glad to see your 3-18 working well. Mine did not. Got it directly from Val @ IOR last spring. Incredible glass and reticle. Was able to print a 4.25" 3-shot group at 818 yds with my 7.5 lb 30-06 Ackley Imp pushing 180's to 3000 fps. Shot very well, for about 50 rounds. Then it fell apart internally. Would not focus. The more I worked the power ring the worse it got. I could actually hear stuff inside, grinding around. Sent it back to IOR. Lost my faith in it. End of story.

Keep your warranty paperwork close by.

Big Al

I have thought about doing the box test but I would like to see more rounds shot than the above post. I have considered using my Savage 22-250 which is capable of around 0.25-0.3" at 100 yds. Run the circuit until you have 5 shots in each group. If you still have 0.25-0.3" groups (assuming no called pulled shots) then you are in business. It would be cheaper to shoot that than a large bore shooting accubonds and double the powder.
Repeatable AND consistent are the two factors, and I think 5 shot groups would tend to show both factors better.

It would just be nice if quality control were such that you could buy a quality scope and count on it right out of the box every time. It's nice to dream.

IOR scopes claim a true .25 moa or (.5 moa) which is not .25 inches but .26175 (.5235) respectivly. At 110 yards one click actually equals .2885 (.577) and one moa is 1.154 as compared to the 1.047 true moa @ 100 yards. Your target is the standard 1 inch squares you will not be "dead nutzs" on anything if your tests do not relate to each other in accuracy.

Dave, I did a little calculation base on your number and I have these result

1.154X3=3.462-hole no.2 target measured about 3.5" high and 3.75" right of hole no.1
1.154X6=6.94-hole no.3 target measured 7" below shot no.2
1.154X9=10.386-hole no.4 target measured around 9.8" gave and take from hole.3
1.154X6=6.94-hole no.5 target measured around 6.75" gave and take from hole.4
and finally shoot no.6 overlapped shot no.1

That's pretty darn close, considering the limitation of my test with an afternoon wind at our range to contained with and questionable shooter's ability. I think that tells enough about the scope tracking ability.

I made the biggest mistake by posting this at the Snipers Hide Forum and they almost crucified me over there. I only have Scott from Liberty Optics bailing me and they dumped on him too. I should have stayed here on friendly turf. Live and learn.
