I've been googling for the 22-250fmjBT and couldnt find any company that makes them. Does anyone know a manufacture that sells these types ammo? I dont have a reloader kit so I cant reload the 22-250 fmjBT.

federal has a bthp that might work for you.  it looks like it is fmj but has that little hollow in the nose that serves more of a ballistics function than a wounding function.

pmc silver line also has a similar load.  and according to their site the hollowpoint is inside the jacket.  

i am not sure if winchester's "usa jhp" is the same as the above but i think it is.

remington has 2 umc loads that might work.

i hope i was able to help you out.  

thanks, I might get into loading now that I've got a good rifle.
