Re: 7mm groups @ 200
Some times it just does not work out like it should. You are not asking to much. I do load development at 400 yards for just that reason. I would shoot farther out, make a note of your current load and then go back to the drawing board and retune it at 2-400 yards, then check it at max range before settling on a load. I have a dragunov that does 1.5"@100...... 3"@200.....4"@500......and 12" @ 1000.......... can't explain it.....sometimes you just have to shoot em to figure out what they will do.
