I've had L461 Vixens in 221, 222, and 223. The 221 was a nice idea but not worth it after the honeymoon. Furthermore, they are not quiet! A 223 with a mild but full power, or a Blue Dot load turned out to be much more practical and satisfying, but then again, I'm not wanting to have a large collection of rifles that require diagnosis to get them to shoot their best. In my view, Blue Dot in a 223 made the Hornet and 221 unnecessary.
I'd stay away from those Blue Dot loads....
As many folks around here will tell ya " you'll shoot your eye out kid!" Ask Ralphie...
