I loaded up some 170 gr RD boolits with a 10 gr. load of Red Dot in my .308, and the same boolit with a 17 gr. load of Herco in my 30/06. At 100 yards I never hit the paper with the .308 untill I fired a round at the 25 yard target. Seems that at 100 yards my POI was about three feet lower than POA. When I got that figured out I started to get decent groups. Not great, but decent. The load for the '06 was more or less to fire form the brass to the A.I. configuration that the rifle was rechambered to, and at 100 yards it was shooting about 10 inches below POA. The boolits were lubed with CR and there was no leading at all. Both rifles are single shots, the .308 a Savage Model 12 BVSS-S and the '06 a.i. a Ruger #1B.

You've got room to pick up a few grains of Red Dot, which will help your POI versus POA. My 14 grain RD '06 loads hit about 5 inches lower than j-words at 25 yards, I don't know if that's all velocity or some barrel harmonics, but I do know that's going to be a lot of drop at 100.

I'm a cautious sort that starts load development at 25 or 50 yards and works out from there. Too many minutes playing "where'd it go?" of precious range time when starting at 100, especially with very new loads.

HI,
I have found that all SQUIB rifle loads shoot way lower POI than normal jacked loads. Big vel. difference you know.:Fire::Fire:

Normally I'll start a new load at 25 yards to see where it's going, but today I didn't. I didn't stop to think that there would be that much of a drop. I won't be using the .308 load for anything, I was mostly looking for a mild load what wouldn't separate my wife's artificial shoulder joint. She's afraid to shoot anything more than a .22 rimfire due to the surgery and her disease.
