Wasp jakhammer for elk?

[280rem]

Just wondering if anyone uses these broad heads for elk and what the results have been for you? I’m shooting a 535 grain arrow in the upper 280fps, been kind of tempted to try them for elk. Have had great experience with them in general and been extremely effective on deer for me in the past.

I shot them over 15yrs ago in Montana. Killed 8 Bulls with them with zero issues. All but one was a pass through. It lodged in the off side shoulder. None of the elk made it very far. Blood trails Stevie wonder could follow. Have no clue about the new ones since I’m in Idaho now so only shoot fixed blades.
