A Battle Sight Zero for the M-4

There is an old school graphic for the M-14 (7.62 NATO) which has been floating around for awhile now (hat tip WRSA). The point of the article and graphic is for a shooter to have a single zero, and to memorize holds.

This is a great concept for carbine shooters as well as battle rifle shooters. I have made an updated graphic for a new generation of gun owners. This is for the M-4 series of weapon, firing the M855 or M193, with the standard Army 300 meter zero. At this zero and these rounds, the holdovers are correct due to the higher MV of the M193 balancing against the higher BC of the M855. Use the comment section to tell me what other graphics to make. Without further ado…

Deer Behavioral Patterns

Timely article from WeaponsBlog on deer behavioral patterns. Of course, I already got my doe for the year…

As the rut progresses, vegetation begins to die off resulting in depletion of food sources in wooded areas, and the trees start shedding leaves. This is the time when the deer move into open areas in search of food but feeling insecure in such places they prefer to move around at night. During fall, deer movement is at its peak between 4 am to 8 am and 4 pm to 10 pm. The very little movement takes place between 8 am, and 10 am. Studies carried out to assist hunters in gauging deer movement have revealed the data. The deer travel the farthest distance during the morning hours perhaps because it has an urge to return to safe shelter before darkness sets in.
