Hey dean, i would pass on working with the sight untill you settle on a final load for the gun... If your gunna up the charge of unique, or switch to 2400 or something like that, you will have to adjust again..... Looks like the load you have in it is grouping well, but i am sure you are gunna play some more before you settle on a load....
It sure does shoot nice it seems, no sign of keyholing... Might wanna try to shoot out to 100 just to see what the holes look like even if it is a long way for you tired eyes...lol ... Dont forget the Bi-focals.... He he...
Also might be cool if you can shoot some into some sand or something and recover a couple boolits to see (with bi-focals of course) how they are engraving..... :)
