Would it be good on Sambar at an appropriate distance ?, yes of course it would. The English used it on Sambar in India as it was quite a popular cartridge in its day. I probably wouldn't use it past 150 yards though as is only around the 2000fps mark, however if loaded with the Woodleigh 270 grain RNSN bullet it will be a ripper deer cartridge.

Waidmannsheil.
