i wont test loads closer than 100yds...

closer than that, things can be too tight to read...

for example, i shot a 1 ragged hole group with a charge at 35yds or so when i was getting my scope close...100yds that same group was well about a 2"er...same results twice at 100yds..at 35yds it looked like a winner though...

200yds IMO will involve more shooter error and make things hard to judge....
