!st Thanks for all the help and insight.
What I am thinking about, I am hoping to buying a metal lathe about 8x32 benchtop unit.
What I want to build is a .172 pcp for shooting lead free ammo for say a 17fireball.
I am thinking a hatsan 17 cal neutron star and a 17 HMR barrel sleeve installed. Hatsan NeutronStar Specs
Max Velocity 1400 fps
Overall Length 43.5"
Buttplate Adjustable
Function Repeater
Weight 8.4 lbs
Scopeable Weaver & 11mm dovetails
Suggested for Small game hunting/target practice
Caliber .177" (4.5mm)
Muzzle Energy 37 ft/lbs
Loudness 3-Medium
Barrel Length 23.0"
Shot Capacity 14
The new barrel would have twist rate of about 1 in 9.
Questions Is this a doable idea and would the pcp have the power to shoot and stablize the bullet??

I have attached a screen shot of a barrel liner for reference.
I hope i have given enough information for you to see whats jumping around in my mind, also any recommendations for a lathe for less then about 1300. USD would be welcome as well thanks for an help available

Not going to work, all you get is a bullet stuck in the barrel.
Powder burner bullets wont work with air unless you use a sabot and bigger barrel.
Too much force required to engrave the rifling on the metal jacketed projectile.

Impossible just takes a little bit longer to achieve.
If an engineer is not presented with a suitable problem, they will create their own!

I bought the NOE bullet mold in the link, Ended up decking the mold and opening it up to .178 to drop a 18.5 gr slug, that will shoot 910 FPS in a Mrod with factory barrel.
