I recently put a piece of electrical tape with a 1/16" hole on my shooting glasses and I got to try it out this weekend. It gave me a much, much clearer sight picture but changed my POI somewhat.
I had always shot 80 grain charges for everything before. But, with my vision problems, changing charges didn't seem to make a difference to my shooting. At 25 yards I was right on but at 50 yards. Results at 100 yards were a $#@* shoot.
After putting the tape on my sight picture vastly improved. But it had an unexpected result as well. At 25 and 50 yards it raised my POI about 2 inches.
At 100 I didn't notice a change in POI because I never shot much at 100 as it was a visual blur. I could hit the paper but that felt like an accomplishment and it had no consistent group.
So, I dropped the 25 yd charge to 70 grains and it zeroed well with three shots touching in the 10 ring.
At 100 my first 3 shots were about 3" low and a 3" group. I upped the charge to 90 and the group closed up to about 2". So I upped it to 100 and with six shots blew the x ring out of the target. Never remember doing that ever. So I am pleased with that.
Now my problem is I'm zeroed at 25 yards and 100 yards and 2" high at 50 yards. 70 grains did not move the POI down at all it's in the same spot as it was with 90. About 2" high at 50 yards. Holding low 2" at 50 yards puts the POI right on, is that the solution?
Should I go try a lower charge for both 25 and 50 or create a different charge for fifty. I need to experiment more.
Any suggestions? I don't want to adjust my sights.
