something vague

I bought some PMC .223 Rem 55gr FMJ ammo at a gun show a few months ago for my brand new Ruger M77 just to have something to shoot right off. I get home and chambered a bullet and found that these bullets were too long for my chamber/throat. I had to really crank the bolt closed and found that it was touching the lands in my rifling. I have found that a lot of factory ammo will not fit this gun as the throat dimensions are too short. After checking with some Hornady 52gr. BTHP match bullets my max COAL is 2.218", which I find to be pretty short. I can deal with it as I am a reloader and will tailer my own ammo as neccessary.
My question is, is it safe to pull the PMC bullets for the brass and leaving the factory primers in them and tailer my loads to these cases? I will have to clean the inside necks because PMC has used some type of black substance that is sandwiched between the bullet and neck, it almost looks like tar. Has anyone seen this before? It's a no wonder factory ammo can be so dirty. Will I have to assume that these primers are magnums and work up with that data as they used some type of ball powder? It looked just like H335, but I'm sure most balls look that way.
