What EV spread should I give my Heracross?

Question

Planned set:

Heracross (F) @ Assault Vest
Ability: Guts
Nature: Adamant
- Megahorn
- Revenge
- Stone Edge
- Knock Off

I'd like to keep the Nature, as its already bred... but if it should be changed that's fine.

EDIT: I also want it to be a bulk sweeper, instead of just a regular, fast sweeper... sorry! Should've mentioned this the first time...

Answer 1

252 Atk, 252 Spd and 4 Sp. D. Adamant and attack EVs will boost its sweeping power, and speed will help it go first. Sp. D Is for that Assault Vest you gave it. You may want to change up Adamant for Jolly for the extra speed boost, though.
