Thanks very much for all the feedback, very much appreciated š Really handy to see how it was done using an identical set up.
I originally chose the Creedmoor round as my RPA .223 is pretty awesome to 600 yards with 69g matchkings, but struggled in windy conditions. I did consider some of the more punchy calibers but the running cost are just a bit too steep for my pockets at the moment. Looks like the 147g ELD match are the way to go paired up with RS60. Reckon Iāll start the load ladder tests in the spring, letās see where it take me. Thanks again for all your input, I literally couldnāt achieve this goal without your help.
