Sidebar...is anyone noticing differences in group size between interbonds and GMXs?
Personally I'm not much of an experimenter. When I find something that works I just stick with it pretty much until I'm forced to do something else.
I shot the 139gr and 162gr interlocks at everything for years. 162's for larger game, and 139's for White tails, Antelope and predators. Outstanding performance always.
The Interbond has as good of weight retention as the interlock, it's just a different design lacking the cannelure and a much higher BC.
We shot prairie dogs in S. Dakota with the 139's a few years ago and out to 600yds they were still doing the job well enough to splat'm consistently.
Between it and the factory .204's with the 32gr Vmax's there wasn't a prairie dog we could see that was safe.
Hornady and Norma worked up some special loads for us many years ago when we were testing some .308 norma mag's for sniper applications and I got to know a lot of the people there personally over the years and have just had a wonderful relationship with them ever since.
