Elk is identical to our Bangladeshi sambhur deer in size , so my favorite premium bullet for them based on personal experience , would have to be Winchester Silvertip soft point bullets ( if they were still being manufactured ) . My clients from America used to LOVE Winchester Silvertip ammunition for sambhur deer and other soft skinned game , like Neelgai , cheetal deer , panthers and royal Bengal tigers .
If you were not a Winchester man , then the Core Lokt soft point bullets from Remington were just the sort of thing for you.
For thick skinned game , the heavily steel jacketed metal covered solid bullets from the American company , Hornady were considered to be the best. However , this was all 50 years ago . Modern ammunition choices have made these bullets obsolete.
I have read glowing reports about the Swift A frames now as being THE BULLET for soft skinned game in modern times. Among bullets for thick skinned game like elephants , the solid brass monolithic bullets have completely pushed the old metal covered lead core bullets of my time out of the picture. Recently , l saw a friend bring some Barnes Banded Solids in the calibre : 9.3 × 62 Mauser and l was really impressed by their construction.
