wind drift. Its a killer at 600 with a 69. At 1000 even the 80s get bucked around. ITs the reason I went to 90s.
Even at 300 the 69s drift more than comparable 75/77/80ish bullets.
Anyone can grab a rangefinder and adjust elevation, its the windage thats a SWAG.
Miss with a 69 doesn't kill a PD but a hit with a 77 will....
Someone here, I thought it was Fiddy, commented about the 69s shooting very well all the way to 900. Maybe I got the wrong guy, sorry.
