Shedding is affected by photoperiod, nutrition and genetics all of which affect the hormone balance that triggers shedding. Most in the rockies will start losing antlers in mid to late February, but others in the same area could drop in January, while others won't drop until mid March. They don't normally shed both sides at exactly the same time, which is why it is rare to find matching sets. But they will shed within about 2-3 days of each other.
Yes it means the length of daylight. Nature uses photoperiod to trigger many seasonal reactions, rather than just weather, as a cold or hot, or wet, or dry spell could be disastrous if that was a plant or animal's sole indication of when to rut, drop leaves, produce seeds, drop antlers, grow a new coat of hair, shed current hair, etc.
Accuracy. What an incredible way to give yourself a true advantage.
Go to your club and get a bunch of guys together - and put a target out there at 250 meters. Break out the deer rifles and see who can shoot a decent group, even off of the bench, at this distance. I think you will be shocked at how few can do it.
So - with that in mind, I recently set out to try to develop a semi-custom rifle that I could afford and that would shoot - repeatedly - at MOA.
I started with a platform that I love...
