I'm going to possibly be building a new 6.5 short action for hunting purposes going for a light carry rifle . Going to be hunting deer mainly . What suggestions on caliber want to be around 3000 fps with the 142 grain hornady eldx. I was thinking the Sherman short or the saum but not sure if there was a round that was easier and cheaper to load for since I don't shoot a ton ??? Thanks in advance.gun)
