.22-250 Ackley Improved: Any significant advantages?
The coolest thing about a Thompson/Encore is that you can interchange new barrels without having to get a new rifle.
Nevermind the fact that barrels cost $250 to start. Oh well.
I have a 22-250 IMP barrel, the standard 40degree shoulder and have not really worked up hotter than standard loads. Unfortunately, I don't have a reloading manual with proven loads for the improved version and so am a bit reluctant to venture much over the hottest 22-250 load as listed in the book.
The biggest advantage as I can tell is longer case life as the brass won't stretch as much.
If anyone has any first hand knowledge of the 22-250 IMP or knows anyone who has had experience with one....I sure would like to get your input.
I should think it wouldn't be safe to substitute 220 Swift data and use those numbers to reload 22-250 IMP cases as both cartridges use different brass...but the performance of each round is pretty similiar as much as Barnes Cartridges of the World has suggested.
Thanks for your input in advance.
