Finally did this yesterday and found a couple loads to try a bit more on as I do prelims with 3 shot groups and then go to 5 to confirm. Found a couple of 5/8" groups at 200yds and 1 group 1/2" at 200yds. That is enough for error on my part so I'll do all three, narrow it down to one load and then do velocity checking to get the BDC correct in the scope. I'm actually adding a forth that is between the 2 at 5/8's since they were only .2 grains apart and most likely the best is between them. Finger is 1/2" group.Originally Posted by CodySPowell
That being said, I was doing some loads with 2 different barrels and one barrel is incredibly more accurate than the other. Sometimes you get what you pay for as one is a 700.00 upper and the other is 219.00 upper. If you can swing it get a White Oak Armament varmint barrel in 1:12 and 24". It is rare for anything to shoot over 1MOA. Yesterday on 10 loads all were under with Benchmark. The other barrel all were over but two with CFE223 and it is a 20" 1:8 barrel and not a WOA barrel but I did find one load that did go 9/16" at 200yds and one just squeaked in at 1MOA. Upper center target is the 20" barrel 9/16" group of 3.
I've also tried the velocity way to find the node for loading and have not had much success and went back to the old full ladder of 3 each.
I normally shoot only 40 grain loads with my 24" barrel but all this talk about the 50's, had to try them and glad I did. Can always use another load that will shoot around 1/2" at 200yds if I do my part and hopefully buck the wind a little better. That is my nemesis.
