You'd probably be best off contacting PMC directly to find out. You can also email both them and Remington to find out exactly what bullets they are using and get the spec's on those bullets.
My ballistic calculator has a library of bullets so all I have to do is enter they brand, typed, grains and the program will then plug in the BC on it's own. Of course it has to be one of the listed bullets in the library for that function to work and so if it's not in the library you can enter it manually.

Looking on Ammseek it appears that PMC is mostly using Hornady bullets for their 7rm's.
I didn't see a listing for the 175gr PSP though. Assuming they are using Hornady's for it as well it looks like you have the 175gr Interlock.
Horndady shows a BC for it at .462 .
