Anybody have experience with any of the improved Swift case designs? Looking to re-barrel with a fast twist and heavier bullets for one of these. So far the Wby Rocket design with the 33'-ish shoulder caught my eye. Pretty sure there's some guys out there with the 40' Ackley versions as well. Maybe even a few with the Wilson Arrow type approach where the shoulder gets pushed back a bit. Absolutely LOVE the Std Swift, but not the frequent case trimming - hence the improved case approach. A hair more case capacity probably wouldn't hurt either. I have hunted g-hogs with the .22-.250 both straight and AI versions, fast twist Swift, .22 CHeetah and .22-'06. All were impressive, but the CHeetah and fast tw Swift really stood out. The .22-'06 is way too much of a good thing unless using the really s-l-o-w surplus ball powders and my buddy who built it used a total mad-man 1:7 tw - Godzilla on both the bbl and bullets alike. Not too many bullets that can withstand the launch from that thing and make it past about 50 yds before turning into a grey poof. With that tw you have to throttle back to Swift performance or less to get anything to stay together. 1:8 or 1:9 would've been better choice for harnessing that power of that beast. Anyway, would like to hear your recommendations and thoughts on any pros vs. cons of the various Swift-based case designs w/ respect to case forming, case life or any issues that might arise due to the various versions in body taper and shoulder angle/location. Thanks in advance.
