    This is an interesting caliber to look at. I'm also looking in to 222 Remington. Both seem very economical to shoot.

    You might check the articles on cast bullet alloy strength and pressure at the Los Angeles Silhouette Club site.
    If your pressure is too high for a specific alloy it may strip in the rifling.
    For rifling twist issues you need to understand that bullet length is the most important characteristic. There are several bullet design calculators on line. Play with them to understand the affect of bullet length. PM me if you cannot find them.
