Timing is everything. I suppose the new crop of shooters with disposable income and no desire to reload have a lot to do with the current factory options. I shoot weekly and have not seen a store shelf of ammo in many, many years so have no idea what factory options there are. Don't real shooters load their own?
Anyway, who cares? The CM case size is perfect for most whitetail hunting under 300 yards. It is basically the 250 improved case and has identical volume, necked up or down, which has been around killing stuff for over a 100 years.
You could say I was late to the 7-08 as I didn't get my first one until 1984. I've killed many deer, mnt goats, bear, etc. with the eight 7-08s I've owned over the years. I still like shooting and hunting with the 250 based cartridges, especially for whitetail. Dead is dead and enough is enough. I can pull out the big stuff when I need to, but realize for the most part bullet placement is everything and the amount of powder you burn is just for dick measurements.
