I picked up some Hornady 220 grain Interlock for my 300 win mag. They were on sale and I decided to try something new. However, I can't find any data on loading them. I checked my speer manual, newest available, a hornady manual, few years old, plus multiple online sources, I finally emailed Hornady and asked them, however it could be awhile before I get a response.
Does anyone have the data available, or experience with this particular weight? I was thinking of using the 200 grain loads and seeing how they work, but don't want to chance anything as I am fairly new to reloading.
Thanks.
