Dang... I just checked out the ballistics tables at Winchester's site on the .284. Looks like a heckuva nice little cartridge. With the 150 grain bullet, it shoots flatter than either the .30-06 with a 150 or the 7mm-08 with a 140, and retains energy better than either of them. Makes me wonder whythe .284 isn't more popular.
It's just my opinion, but I think the reason that the .284 never really caught on was because the .284 wasdelevlopedmainly for the M100 and M88.When Winchester stopped making the M100 and M88, they essentially stopped making the .284.Today if it weren't for gunsmiths rebarreling and rechambering existing rifles and custom rifle makers offering the .284,it very well mey have faded away completely.
