First of all, I am new here and this is my first post.  I hunt a lot, mostly with archery gear, but also reload and shoot.  I am a fan of the true carbine-- a rifle that shoots pistol cartridges. I hunt with a Ruger semi auto 44 mag.

I have a TNW Aero SR in 10mm. I just ordered my dies .  I will only load 240 JSP's for my 44 mag.  But, I cannot find anyone who makes a 10mm JSP bullet.  I do see that FEDERAL offers live ammo in Vital shok with 180 JSP.  Where does Federal get their components ?  Where are the 10mm JSP bullets ?
