Dont know if anyone has experienced this so I thought I would post it! I have a Optima Elite 50 cal. and when I got it last year never could get it to pattern always having flyers best group was bout 3.5-4" unaceptable in my book. I tried everything and was about to buy a 32acp conversion when I read a post on GBO about precission bullets and Black horn 209. Well I called and ordered some bullets and bought the black horn all I can say is...................AWESOME! Since changing to the 265gr bullet and black horn I have had 1/2 - 3/4" 3 shot groups @ 100 yards and its is LETHAL on deer out to 200yards I would not hesitate to make a 225-250 yard shot with this set up! Hope this helps! cant wait for ML season to open!
