I`m 61 years young and my eyes arent what they once were..Lately I`ve found my shooting yardage shrinking fast,50 yards was about max for me..Dug out a Merit Optical sight that I bought awhile back and gave it a whirl today..Its a little thingy that attaches to your glasses..Got to playing around at a friends farm to today and this was my target at 125 yadrs sitting on my butt with elblow on my knee holding rifle..Not the best shooting I know but for someone who was limted to 50 yards max this traget made me smile..Now with a lot more practice who knows..Rifle used was a hawken style rifle built by Gary White around 20 years ago refinished by Roy Stroh.. Cal .62 42" GRRW rifled barrel..100 grains of 3F with a .600 ball and a .15 patch 10 shot group
