That was my intention. I saw a lot of talk on 'over-kill' cartridges here and thought it may save someone from learning about overkill the 'hard way', as I did. It's not something that I am proud of.
I would think that 7STW's, 300 RUM's, and equivalent could product similar results under the wrong conditions.
That said, I love my 338 Lapua. It is a pleasure to shoot and I'm nearly through my second barrel on it. It is by far my most consistent rifle for shots over 500 yards, especially when wind is a factor, as it was in this case. BTW, I think it is about right for elk (calfs and yearlings excluded).
Since the 'incident' I've been using my 243 win and 6mmART40 for mule deer with 105 gr AMax's. All animals shot have been recovered, but there's been more tracking involved than I like. Having a 260 remington built for next year. That may be the ticket.
