A question about AP ammo and DR

After reading few damage formula posts, is it safe to say that AP ammo is not very effective for those weapons with high damage each shot (Black Widow for example) ?

I mean, since DR from armor is 50 in insanity, it is just ignorable for weapons that can easily deal 600+ damage each shot, unless you really really want that extra 1 meter wall penetration.

Thanks

I'm using the Raptor and Avenger for my infiltrator run with AP ammo. I use the Raptor most of the time. Is taking the additional 10% (total 30%) damage to health and armor better, or the additional 25% (total 75%) armor reduction better at the 6th level of evolution?

The Raptor sort of falls in the middle with a pretty fast fire rate but also decently high damage per shot, so I'm not too sure which one to take.

It depends on what you are talking about exactly.

In general, if you have a high damage weapon then you get better damage against armor with Warp Ammo than AP Ammo because of increased damage bonus as opposed to "armor piercing" or "armor weakening." The only thing that matters in this instance is damage per shot, rate of fire is irrelevant.

However, if you have AP Ammo anyway, then with a higher damage per shot weapon just take the Damage evolutions instead.

I calculated break even points for these in some other thread... that is to say at what damage per shot Warp Ammo and AP Ammo were the same, and looking at just each one, where the point was for the difference in evolutions.

Here were the numbers:

if I ran the numbers right, theoretically AP and Warp would give the same damage per shot (if you take damage over piercing or armor weakening) if the base damage is 125. If it is higher, than Warp gives more damage, lower AP Ammo does. If you go max armor weakening, they are equivalent at base of 166.667, AP better below and Warp better above.

For the two evolutions of WA, base damage above 100 should favor damage evolution, and below would favor weakening evolution. For AP it would seem that base above 125 favors damage, and below favors piercing.

This is purely against armor, not against health. Against health the damage evolution would always be better of course.  The Ammo Power damage should be applied to armor first, and is supposedly immune to armor  damage reduction. At least that is the theory.  Additionally, the armor weakening should stack with Piercing mods, and Warp ammo weakening should apply what is essentially a "debuff" that also allows squad members to benefit when they take their shots as well.


edit: I did these calculations a while ago, and the statements only refer to the bonus damage itself if I recall correctly.

What kind of damage bonuses do I get from disruptor ammo?

You get 0% bonus to armor. ;)

Otherwise, look at this:
Disruptor Ammo

What about as a tech burst?

I charge them up with disruptor ammo, then I use my incendiary blast.

If you are talking about on an Infiltrator specifically, I agree and I prefer to run Disruptor Ammo and not take an ammo power for my bonus power. I don't know what the numbers are, but that is how I like to deal with armor as an infiltrator as well.

However, AP Ammo is really a better choice for more punch against armor with SMG's or even shotguns since the former has no piercing mods available, and the latter has a poor piercing mod.

I don't know exactly how much damage a Tech Burst from DA actually does so it would be hard to tell if a Widow shot with DA followed by Incinerate and a Tech Burst really does more damage than a Widow shot with the AP Ammo spec'd for Damage (bonus is something like 300pts) followed by Incinerate with no combo. That is an interesting question.

Ahh thanks, capn233. I believe the Raptor does around 80 to 90 something base damage. My question is now how would bonuses from armor and passives affect this? Or not at all?

Power damage bonuses add to the ammo damage bonus (supposedly), whether those power damage bonuses are from armor, passive or intel. I do not believe that they would affect armor weakening or piercing whatsoever.

In any event, I am not entirely sure how their math works with that, but I believe the effect is relatively small.

That is to say, suppose you had 30% bonus to armor from AP ammo and then you have a 10% power damage bonuse.  It would end up being more like a 33% total bonus rather than 40%.
