Not sure about all the "good, bad, or indifferent" critieria as such could be applied to bolt actions, SLRs, poorly maintained, poor ammo choices etc.

I just come back to the question, why would a double rifle shoot off face or "loose" because of an elephant cull?

Any emphirical evidence that X shots through a DR mean it will be "off face" or "shoot loose"? Any one else want to comment from experience?

The main reason some claim a double is not ideal for a cull is the number of repeated shots that might be needed, follow up shots, emergency shots etc.

And perhaps as with the usual PHs a lack of spending money to buy double rifles. Lots of good PHs have asked me over time how to get a "cheaply" or well priced double rifle when in Africa. If they haven't got one, they can't use one. The amount of $$$ the PH has makes a big difference in the tools he can use. No doubt about it. And cull shooters tend not to be the best heeled guys.

However for a cull I do think a good magazine bolt action of adequate power does seem ideal for mass shooting cows and calfs. Or an SLR/FN Fal. Nothing sporting about it at all.

Interesting though, just watched a video where a side by aide shooter shot ten shots in the same time as a five shot Adler lever action shotgun, when time to reload the Adler is factored in. Alex Beer here on NE was damned wuick with his Ruger No. 1 single shots in fast repeating shooting as well.
