I had been shooting 24gr shockwaves on 90gr powder (both loose and pellets). I ran out and got a good buy on the Hornady SST 300gr bullets. I bought some and went to sight in again but increased my charge to 120gr. Groups at 50yds were close to the 240gr shockwaves at 50yds.....but a bit lower which I expected. The 300gr hornady's where about 1 ½ high at 50yds.

I moved over to the 100yd bench and missed the paper (8 inch shoot-n-see). Swabbed the barrell as I always do (2 wet patches, 2 or 3 dry ones, fire a cap, then run another dry patch down to remove the fouling from the 209 primer). Loaded again and again missed the paper.

I assumed I was missing low, so I aimed at the very top of the shoot-n-see (12 o'clock position) and again, a miss. Repeated the process with the same result. I was completely confused.....so I reloaded and shot at the very bottom of the target.....6 o'clock, and hit an inch high of the center bullseye. WTF?!?!?!?

I went back to 50yds and was still 2 inches high at 50yds. So I'm shooting 2 inches high at 50yds and 6 inches high at 100?!?!?!?!?!

How can that be????
