Hi, I am a huge fan of firearms and I have a plan to build a smoothbore bolt action rifle firing fin-stabilized sabot rounds. The following is what I would do to make the rifle and I would like to hear your opinions on its feasibility.
1. The rifle action and bolt would either be made out of nickel maraging steel or grade 5 (or grade 19) titanium.
2. The rifle action would be designed to accept .308 winchester rounds necked up to .451 caliber (cartridge case thus will have a straight wall).
3. The barrel would have smooth bore with .451 inch of caliber.
4. The barrel would be made of grade 5 (or grade 19) titanium alloy.
5. Since titanium oxide layer would quickly wear out if rounds are fired and this could result in titanium burning in air, every titanium part will be coated with Silicon Carbide via CVD method.
6. The projectile diameter would be approximately a third of the bore diamater with aluminum/plastic sabots filling the gap.
7. A suppressor for the rifle would be made out of inconel. The inside diameter of the suppressor would be same as that of the barrel (.451 inch) along its path with a forcing cone at the point where a projectile capped in sabots enters the suppressor. The reason for setting the suppressor diameter to that of the barrel is to keep sabots integrated to guarantee accuracy, and for this the forcing cone is a must to allow saboted projectiles to safely enter the suppressor.
Assuming that price is not a problem, what do you think of my idea?
