Back in the 80's, I believe, Winchester came out with their "Supreme" factory loads that came in a black box. I started using the .30-06 loads with 180gr. Silver Tips since I was going to college and didn't have time to reload. I shot several elk with those loads and they worked very well. After graduating college, I started reloading again and bought a box of 500, 180gr. .30 cal Silver Tips from Midway. I killed probably half a dozen elk with those as well and was always impressed with their performance. Never had occasion to complain. After that, I started messing around with other cartridges and rifles, so haven't used them since the early 90's, but I would not hesitate to tote the ol' -06 with those 180gr Silver Tips for elk once again.
