It shouldn't be too tough to find .25/06 factory ammo seeing that you live in a major metropolitan area. The guys that are most likely to have difficulty finding it are those who live in small towns where the local hardware store brings in .30/30, .270, and .30/06 in addition to .22 rim-fire and low brass 12 ga. Like all center-fire cartridges, the versatility of the .25/06 increases with handloading, and the cost of the initial setup can be quickly recovered. Handloading will encourage you to shoot more, thus developing better marksmanship skills within a shorter period of time.
