While building loads, I use Sightron SIII 8-32X56 Target Dot recticle scopes. The scopes are good enough that I can usually see the bullet holes in white paper and using splatter targets, you can easily see them.
I'm done with 243 and put a Nikon Monarch 3-9x40 hunting scope on it. While verifying settings saturday morning, I still shot a 7/8" group at 400yds with it.
No special equipment, a rear, sand filled, stock rest and front sand bag rest. Don't believe in using those special contraptions that hold the whole rifle and all you have to do it is put the cross hairs on the target.
Saturday, I did kinda do a dirty thing though. I let a new guy to rifle shooting, shoot the 22-250 at 100yds. He came out to the range with an SKS and 30/30 to target shoot. Both had open sights and I helped him zero them for him, then asked if he wanted to try mine. Having never used a scope, I coached him through adjusting it and had it on 24X so he could see his bullet holes with no problems. After each shot, he would say, you need to look at that. He shot about a 3/8", five shot group and thought that was amazing, the gun will do better than that. He was going to get a scope for his 30/30. I didn't have the heart to tell him just any scope would do that, and that scope cost almost twice what he just paid for both his guns, and there was no way under the sun he was going to be able to do that with his 30/30. He was a long time pistol shooter so he knew how to squeeze a trigger.
