ladder test-visibility question

Have a great opportunity to get to the range this weekend for the first time in months. I want to run a ladder test with my 204 Ruger. I believe it will work best at 200 yards. I have a 6-20X40 Bushnell Elite 4200 on the rifle. With it being the weekend and the range will be busy I won't have a lot of time to experiment with moving targets from 200 back to 100.
My question is has anyone tried to see individual bullet holes at this distance through their scope. I do not have a spotting scope.

I don't have any practical experience with that particular scope, but I believe you should be able to see the shot holes at 200 yards. My 12-24X56 NightForce will resolve them at that distance. The rest will have to be steady and hopefully not a lot of mirage to deal with.

I can see the holes a two hundred with my 63 year old eyes and a 6x24x50 Sightron if I shoot above my point of aim into white paper. On another note, have you ever read about Dan Newberry's OCW load development system. I use this shooting round robin style & it's great for finding a node.

OCW method has proven to be much better for finding a good load than other methods IMO.

Thanks for the replies. I am familiar with OCW load development but this trip I was trying to see what the velocity and pressure ranges were for 2 powders with the same bullet weight. I am not after top velocity but I have tried 'recommended' powders in a couple of my other varmint type calibers and been very disappointed with pressure signs appearing long before I reached anywhere near the velocity I was expecting. Switching powders seemed to always correct the problem. I do understand changing primers, case volume differences, bullet length, etc as all variables that change the results, including pressure.
Will probably try an OCW test next trip.

You should easily see the holes thru Shoot-N-C targets.
