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.
How many times have you wished for a better view across a clear cut, an agriculture field or down a powerline?
Ever wanted to get a little higher to try to get above a deer’s nose?
Have you ever wanted a taller stand because… well… just because?
Here is an example of a stand I made a few years ago and it has some very real advantages and a few disadvantages.
commanding view from the stand
able to accommodate two hunters, perfect for parent / child hunts
hunters are well...
