Not including Z-Moves, what is the highest base power move with no negative secondary effects?

Question

By “negative secondary effects,” I mean things like recoil damage, stat reductions, etc.

I am also not including moves that take a turn to charge, like Sky Attack.

Many attacks with 150 power. https://pokemondb.net/move/all

Are you counting multi turn moves such as rollout or other things such as round, which needs multiple attackers?

How many of these count? https://bulbapedia.bulbagarden.net/wiki/Category:Moves_that_have_variable_power https://bulbapedia.bulbagarden.net/wiki/Category:Moves_that_power_up

Most moves with 150 BP take a turn to recharge, which counts as a negative drawback.
Any move, including ones that vary in power or receive power boosts under certain conditions, is fair game as long as it is not a Z-Move or has a negative drawback. If that’s too difficult to answer, I can narrow it down more.

If you’re looking for a reliable strong move with o secondary effect Earthquake has always been my go-to move for that.

Answer 1

Rollout can reach the highest base power of all moves, tied with Ice Ball; if the attacking Pokémon has used Defense Curl and Rollout hits for a fifth consecutive time, its base power will reach 960.

That’s right. But seriously, how can anyone ever makes it to the 5th turn?

It's nearly impossible in competitive battles, but it answers the question.
