Karen's .250 Ackley is nothing short of superb. If I took it away from her and sold it, that would be the end of a 49-year marriage.
In recent years, the quality of .250 Savage ammo and .250 Savage brass has become really awful. Because of this, I neck-up Winchester brand .22-250 cases in a Redding .250 Savage die with a loooooong Redding tapered expander. It helps to use a VLD inside neck chamfering tool and just a touch of lube inside the necks.
Then, of course, the cases are fireformed, as normal
The .22-250 cases converted to .250 Ackley are nothing short of superb.
Blessings,
Steve
What I also like is finding a suitable .22-.250 rifle and rebarreling that to .250 Savage. There are lots of the former available, and almost none of the latter...
