Interesting day at range today. Went to sight in my 15" Encore 460 S&W with new Simmons 4X scope. Due to 40 to 50 MPH winds today, jujst shot at 25 yards. My 45 Long Colt Corbon 300 grain +P and 454 Casull 300 JSP shot to the same point of aim. My 460 Corbon 200 grain XPB spitzer shot 8" below them. I thot maybe the scope blew, but fired a 3 shot group with the 460's and then tried the 45 Colt and Casull loads again and they were right on. I guess I need a ballistic table for the 460 huh?
