Re: 220 Swift /. 22-250

I currently shoot a Ruger M77V in .220 Swift that has been re-barreled by Douglas Premium with a 1-8" twist barrel , 26" length , standard Ruger factory varmint barrel contour . I shoot Hornady 80 gr. A-Max bullets , Winchester brass , Federal 210M primers , and Hodgdon H4350 powder , at an average velocity of 3305 FPS, measured 20 feet from the muzzle , by 3 different brands of chronographs . ES is 20 fps .
I have not killed any animals , yet , however , it is consistently less than 1 MOA at 1200 yards on steel . At normal ranges , 100 - 700 yards , it is consistently 1/4 MOA .
I shot it in the Texas F-Class Long-Range matches in Houston , last March , and at 1000 yards , it held vertical dispersion of 1/2 moa , however , my inability to read the wind lead to horizontal stringing . The rifle/cartridge combination is much more capable than I am.
With a zero range of 200 yards , I needed only 19.8 minutes of elevation to reach 1000 yards , at Houston , although my G-seven ballistic information called for 22.3 moa .
I think this combo would be very capable on antelope at 700 yards , as it is still near 700 ft/lbs. energy at that range .
I have shot approximately 700 rounds through this barrel , and accuracy seems better now , than when new .
