i switched to front shoulder shots 90% of the time just to eliminate runs. doesn't always work, but usually.
I went the other way. No neighbor/property issues, so I go big and slow behind the shoulders to save meat. Easy to find when they're leaking from two big holes.
My experience with a .223 ttsx on a shoulder shot tells me that speed+bone=less running though. If running was an issue, I'd be shooting shoulder too.
