Swapped out for a slightly lighter AR15 hammer spring at 4.5 lbs and going to go thru every brand I have but was wondering what factory ammo is generally considered the hardest to ignite? I would think a reletively small decrease wouldnt have much cause and effect but checking anyway.

CCI is usually the hardest primer, not sure what factory ammo uses them.

CCI #41 (small rifle) and #34 (large rifle) are the only DoD certified primers.  They're the hardest primers to ignite.  Federal M193 and M855 both use #41 primers.

Why are you going to a lighter hammer spring?

For a lighter trigger pull, i would assume.

good to know, thanks.  would you know about ADI primers?

no particular reason other than its a 2nd spring that came with a tg I got a while back. just want to see how it feels, if it promotes more accuracy/follow up than the current spec one,altho  not that its too bad now. just playing around with extra parts.

You'd have to ask them.

Aren't the Russian primers (Tula and the like) harfer than even CCI's?

IM not sure but the #41 are specifically harder for 5.56 military applications.

 

Standard CCI primers arent all that hard

I don't know for sure.  Based on what I've read, some seem to think they aren't necessarily harder but less reliable, requiring a second hit to detonate and thus being interpreted as harder?

+10000. That. I agree with from what ive heard other shooters at the range say.
