Beeman you just built my gun... well at least w/ the same stock. How do you like it? I'm waiting on my stock right now I have my bart barrel, stiller action, and jewell ready to go.
Timber, I've often found myself trying to duck not so low limbs and still getting hung up on them. My point to the op is though longer is faster it may not always be better. The reality of it is that 50fps amounts to a pile of fly crap in your pepper, you'll never see or know the difference. If you're running a thin contour the longer the barrel the more whip you get and the more finicky load development can be.
Hell, split the difference 25" or get WILD and go 24.75". My smith has built a many 300wm at 25" for himself and others. I may do the same w/ my 26" blank.
Then again, you can always cut the barrel down. But make sure you chrony it first and report back to use after the snip.
