I picked up a Ruger 300 RCM and was wondering if the M77 Hawkeye would need some barrel relief as it is quite tight against the stock...? Also, I was considering adding a Leupold VX 3 2.5 x 8 -36 scope and wondering which size rings would be needed...? When I got it it had peep site on it - so I'll try that first and see how that works. Your comments and suggestions are appreciated.
