Thank you much sir!! 19 years of trying and frustration finally paid off! lol
Yep, it is the shoulder that broke. Camera angle don't show it well, but he fell on an incline into a dried up creek bed. Was somewhat of a pain to get moved around to field dress and it took 3 of us 6 hours to get him back to the truck. This was in 07, 1st rifle season, not far from where you call home. Love Buena Vista and the valley's scenery!
As to the .30-30, we still take one along every year with the same 170 gr. bullets you mention. Dad killed a few elk with it over the years while beating the timber.
