While I have not loaded any in years, I always found the old bulk box (500ct) in 5,000ct case ones either hit or miss in the accuracy department. In some calibers, rifles and loads and for their then price, they were great, but in a few others, only ok. Impact performance within their range was good, and they killed well. At the time, I was a licensed ammo reman/manufacturer, and I loaded a ton of these in varied calibers and without complaints from my customers. The 270, 30-06 and 30-30 were my best sellers.
Today, I still have a few of the old brown box 500ct with a few left in each: 243, 257, 270, 30, and a couple of others, but now, I almost never load them. It is an eye opening experience to look at the old package slips and see what I paid for those, and some were under $5/100 in bulk.
