If I use a .220 Swift and you use a 30-06 necked to .224 you will use about 20 grs more powder per shot. At the 5000 shot mark I will have saved $285 which should pay for a new barrel!

<br>I still have to find out more about this .220 H . So far it's hard to believe.
<br>
<br>But more powder costs more, gives more recoil and more blast. And it does go against the modern trend of the low aspect ratio cartridges like the PPC and now the .300 WSM and SAUM.
