The core-lokt isnt a bullet that i would be sighting in at 300yards IMO. It performs its magic at closer distance's normally. For long range look at the ballistic silvertip or the accubonds....something along them lines!! Good luck!
If you want I can run that through my balistics calculator? When you say sight in for 300yds, you want it to hit at zero there? I suspect the MRT will be fairly high like that. I like to zero hunting rifles with MPBR at a 6" target. Then the farthest the bullet will rise above line of sight is 3" and you'll have a MPBR where the bullet falls 3" below lone of sight.
Being a bowhunting I've always been fanatical about scent control. Whether it's sprays, carbon clothing etc. I've tried it. The best thing that I have found for eliminating human scent is Betadine. It's been used in hospitals and homes for decades as a defense against infections on minor scrapes and burns. It can typically be found near the pharmacy in any of the major "one stop shop" stores, and a bottle will last multiple hunting seasons.
