I just finished testing in my 220 swift. They shoot well, between 1/4 and 1/2" for 3 shots at 100 consistently, but they need to be pushed hard. I seat .020" off lands, and max load of IMR3031, for 4450 fps avg in 26" barrel. I did take them up to 4670, but that was hot loads. Did you try the 8208 with them, pushed to max? Barnes recommends .020" from the lands.
