I decided to build a 700mm FX barrel kit for my Veteran today. I have made full 500mm and 600mm setups for it already using heavy duty steel sleeving, but I needed to get a feel for a full-size 700mm and figure out whether or not it needs an outer shroud. Used a new FX Superior Heavy liner that I polished up on my lathe, then scuffed the crap out of the exterior so I could apply an anaerobic gap filling bonding agent for the carbon fiber sleeving.
That gave me a little idea to split the long unidirectional tubing in two pieces, and then I machined down a larger diameter piece from a high-modulus tube that I had custom made for .25 barrels. Doing this really ensured that there was a nice uniform coating of the bonding agent from end to end, and the coupling in the center was sanded down so that it was like a press fit to the inside of my custom barrel sleeve. (Side note - I have found that thinner unidirectional tubing works just as well as thicker / higher modulus tubing for clear improvements to accuracy when using the right bonding agent.)
Dying to test this thing out. It has another 10 hours to cure, but if this 22cal FX Superior Heavy liner is as accurate as the other one I have, it should be able to snipe lime size targets at 300y with 40gr slugs! (Havibg stellar results with Griffin BTs and some FBs that D-RIG sent me to test in a BHN-9 hardness).
I've had this turned up to 120FPE using a 700mm CZ with 55gr sided to .217 (single loading, they will not fit in the mag), but unfortunately the 700mm CZ has an extremely tight bore and only seems to prefer lighter slugs

.. but yeah, the weight is always on my mind! This is a great hunting rifle with its monster power and accuracy. It would be near perfect for hunting in the mountains if the stock fore-ends weren't designed for benchrest. I had planned to trim down and lighten a couple of the factory beech stocks, but I have some other ideas that I'm hoping to (find the time to) bring to fruition .. think along the lines of Sabre tactical on a weight diet for Taipan.
