Myarmour, I was using winchester FMJs to break the gun in but my local shop ran out of them. I grabbed some Remington 55gr FMJ and found they flew fantastic so I took them hunting with me. The full metal jacket rounds do very little damage to the hide going in or out which is nice. The only downside to them compared to an expanding or exploding type round is you have to get into the vitals to kill em real quick. Seems to be working ok for me right now. My last four yotes were taken with FMJs.
I have done a lot of work floating and bedding my barrel. I have shimmed a little here and a little there to get the action straight and snug.
