RE: T/C Maxi-Hunter, Maxi-Ball?
You might consider a peep sight. I am far sighted and over 65 and I find the peep sight helps to get me a good sight picture as well as a good target picture. You might be able to use a scope with no magnification; have you asked about that??? 295gr. Powerbelts with the aerotip penetrate rib cage and pass through elk (at least mine did this year) with only 90gr. of Black Mag'3 pushing it (was about a 90 yard shot).
