Well, you got your info on where to go and who to look up…

Bout the only thing I can offer is that you take ONE WHOLE DAY and devote it entirely to shooting fundamentals. Sight picture, trigger control, proper breathing technique, different shooting positions (standing, kneeling, sitting, prone), effective use of a proper shooting sling (M1907 type), use of iron and also optical sights.

You get your fundamentals down, the rest is cake.

The wicked flee when none pursueth..." - Proverbs 28:1
