Anyone familiar with the bullet used in the Winchester USA 22-250? It's listed as a 45gr jhp and under that it is listed as "Varmit"? It's a wicked looking little bullet with want appears to be 6 "leaf's" at the tip. Each of these appears to be a hollow point of its own. The outer edge is "scored" along these "Leaf's". I don't have a bullet puller yet, on order from midway, or I'd pull one and see if it's boattail. Not listed as such. My rifle really likes the factory load and I want to try to duplicate or tweek it. Thanks for the help.
