As many scopes as I run through the wringer just to test tracking, I figured I needed a dedicated gun for it, so that gun is in the works.  It'll be a .223-cal Tikka T3 Varminter (here Wednesday, if I am lucky.)  The round is small enough and slow enough to allow for ALLOT of fire in a short time.  Also, it is cheap enough to put 60 rounds down the tube and not break the bank.  And recoil ain't a consideration, so no problems there.  (Some might ask, "Wouldn't you want to test recoil durability?", and the short answer is no, not on a rifle built to test tracking. A scope that cannot withstand recoil doesn't meet the absolute minimum requirements.)

Proposed torture test is as follows:

Boresight and zero on a target. Verify zero. Move to new target.

My target of choice is a 12"x12" target with 5 bulls (one dead center, one on each corner, exactly 4 inches diagonal to the center bull), taped to a pistol target (3x4 feet - or so.)

First test is box;
Fire one round on center bull
11 clicks left, 11 clicks up, fire one round
22 clicks right, fire one round
22 clicks down, fire one round, 
22 clicks left, fire one round,
11 clicks up, 11 clicks right, fire one round

repeat 3 times for a 3-shot group on each corner bull and a 4-shot group on the center bull.


Next, with 5 pasties posted all over the pistol target board, mil each pasty, dope and fire.  I have verified (and re-verified, and re-re-verified my spotter's mil scale accuracy.)  This allows for running the turrets out to near 1,000-yard dope and running back down to 100 yard zero.

At the end, I have more than 10 rounds in the bull, 3-round groups at each of the other bulls, and 5 pasties with a hole in  or near. them.



Thoughts or suggestions?

So far, it sounds like a pretty tough test. I like it.

Nice rifle choice. I have been looking real hard at $1500 new   XCR dark trinyte finsih over stainless Remmington .223 that is on sale for $799.  It has been on sale for months cause I'm the only one here who knows what it actually is the rest of the crowd takes it for an over priced blue gun. 
I've been wanting it but I have a hard time buying a bolt .223 when my semi autos shoot as well as they do.

Good for training
Laughable recoil
Cheap ammo

I'm all about the 223 bolt gun!

I came so close to buying my friend's .223 Remington Varmenter just to have a cheap to shoot bolt gun and play with scopes. I let another friend buy it so he would have a good groundhog gun and he was fine with the World Class Tasco that was on it.
 
RC, the second part of your test has me a little confused. Are you testing the accuracy of a scopes mildot reticle?

Due to the size of my preferred target, I cannot run 8 mils out and be at a meaningful impact point.  With the dots, I check mil accuracy of longer range dope changes.  I know my spotter is dead nuts, so I mil it on the spotter, check it on the scope (for accuracy), then dope the adjustment and fire.  If the tracking is precise, I should be able to run out 8 mils and hit the dot no problem.

Minor tracking issues can be masked by a poor trigger pull at 1 or 2 or 3 mils (at relatively short ranges.)  At 8 mils, not so much.

Make sense?
