My main purpose in developing this load is to have a round/rifle combination that my 11 year old son and I can both shoot while hunting. Due to his age and where we rifle hunt (Wisconsin) the regulations require only one rifle per Mentor/Youth hunter combination. Since my Barnes Manual did not contain data on this bullet I called Barnes and they forwarded me the current data on that bullet. I had purchased some .224 Barnes 53 gr TSX FB bullets. I am shooting a stock Bushmaster Target Model A3 Rifle. It has a 20" Chrome lined heavy target barrel with a 1:9" twist. I selected Varget as my powder of choice as I use it in several other rifles cartridges I reload for. Accurate 2230 and 2520 were also considered. I was shooting at a range of 100 yards. I am shooting with iron sights. My starting load was 24.5 grs. stepped in 0.2 grain increments with the heavy charge being 26.3 grs. Shooting from a front rest my tightest groups averaged a standard deviation of 0.88 inches and centered around a charge weight of 25.3 grains. What is really nice is these groups were only 1" lower at 100 yards than my current target round. I don't think the dead deer will mind that much. I will be getting some Barnes .224 62 gr TSX BT in the future to work up a load. I have used Barnes TSX bullets in my BAR .30-06, Winchester Mod. 70 .300 H&H Magnum, and Rem Mod. 700 7mm Rem Mag. with great results, I have never had to track an animal I shot with a TSX.
