How much damage would a Weavile using beat up do in this scenario?

Question

I have 5 Kartana fully EV/IVtrained in attack in my party, Adamant Nature. Adamant Weavile with 252 attack EVs and Max IVs in attack uses beat up.

Is there anything that wouldn’t ohko( not counting boosts and held items).

Answer 1

Base power = (party member's base Attack) / 10 + 5

source
Weavile's base attack is 120, and each Kartana's base attack is 181. So the effective total base power would be around 120/10+5+5(181/10+5), which is 132. (note that I'm only rounding at the end, which might make this calculation inaccurate) I shall now demonstrate its power against the second best Pokemon in OU.

252+ Atk Weavile [132 BP] Pursuit vs. 252 HP / 252+ Def Quagsire: 178-211 (45.1 - 53.5%) -- 39.5% chance to 2HKO
