14" =355mm near enough. If true my jw 15 will be min legal length in 5 min

I've been doing a bit of reading as well as chatting to a few different people who ought to know about this stuff and apparently in the case of rimfires a longer barrel isn't always better. With a 22 apparently once you start getting over that ideal length all the extra barrel does is slow the bullet slightly due to friction. I'd do a bit more reading on that around the 22 but it could be interesting. Those little Savage shorty's are interesting (they're really short) but after reading an article in NZ Guns they were getting speeds around 800fps with CCI subs (well below the 1000~ you normally get) so again, more reading is probably a good idea.

I've seen a few test of the .17HMR in particular and it was quite interesting. Have a read of this: HMR Velocities
