RE: How do you practice and how much?
Starting in January........Field Points and 3D until just before turkey season. Turkey season.....I shoot expandables.....and I hunted most every day. No time for practice.
After turkey season....it's back to FP's for some indoor 3D (it's HOT, here!) a couple to 3 times a week (sometimes 5 days). Come August.....I'll switch to BH's and won't shoot anything else until after deer season.
Repeat.
