I have a 22/6mm (224tth). It shoots a 75 gr. AMax very well. I'm wanting to shoot a similar weight bullet that will perform better on small deer and antelope. The AMax goes to pieces. The Swift bullet is the only one I see that might fill the bill. Does anyone have any experience with this bullet or the Scirroccos in general? My barrel twist is 1:8 and current velocity for the AMax is just under 3700. Thanks much.
