With antelope being the primary target, and having several doe kid tags to fill, my target weights were at or near 100 pounds. Now I was setting out in northern Harding country South Dakota, with the first in my pair the handloaded Barnes 62-grain bullets. The handload pushed the Barnes TST at 3628 fps behind a burning mass of Varget in a 38.5 grain charge. This load was max for Varget and the Barnes bullet but was able to stay close to the Swift even at its increased grain weight. As an example, the .220 Swift when loaded with a 53-grain Barnes TSX FB bullet leaves the muzzle at a maximum velocity of 3882 if pushed by a 43.5 grain charge of AA 2700. “Yes, a couple of hundred feet faster,” you’re saying – but also a bullet nine grains lighter with less kinetic energy on target after the speed thing begins to dry up a bit down range. In my book it all balances out when comparing very high velocity loads and modest grain weight changes back to back. Speed kills, and with light bullet and small calibers you can’t get them moving fast enough. Even a slight change in grain weight can return major dividends at the target in terms of raw energy, which translates into killing force.
