We can find great deals in spam cans for the 5.45 there is no doubt about that.
But lets start with simple hard facts so we do not get all wired up with personal favorites and opinions.

- Identify available loads in both calibers with all data about the loads.
- Post data about internal, external and terminal ballistics.
- Options of bullets and specialty loads for different purposes.

Then we can start a comparative and healthy discussion w/o any mythology involved about poison bullets vs bad ass loads.

5.56x45 has a ton more loads available, a TON more loads.

5.45x39 isn't much cheaper it is comparably priced not counting the corrosive stuff that I try to avoid, and from everything I have seen in tests, reading numbers and things like that, the average 5.45 is equal in accuracy, penetration and stopping power when compared to the average 5.56.

give me crap all u want guys, I say the 5.45x39 = the Russian 5.56x45

No man this is not against you man. I understand your point. But I just wanted to post some important info here that otherwise might not be so clear to other people. Again I get your point and I respect your opinion.

O I know it wasn't against me I thought u were starting a discussion thread in the proper topic form so we didn't fill up that guys other posting, haha, I'm not offended or anything, I just figured if other people read this they could discuss with me since they might not have read that other post we were posting in.

Reference...

Cartridge : 5.45x39mm Bulgarian 53gr boattail steel core FMJ

Firearm : Romanian AK74 with 16.5" barrel length

Block calibration : 9.5cm @ 578 ft/sec (no correction applied due to bullet tumbling)

Single shot fired to the center of the block from 10 feet distance. Bullet impacted at 3014 ft/sec, penetrated to 2.5" and turned on its side. This sideways penetration continued until 8.8" depth, at which time the bullet apparently righted itself.

This orientation continued until ~ 9.0" penetration depth, at which time the bullet again turned on its side and continued on in the sideways orientation until bullet exit at 16.0" depth. At this point, the bullet impacted the test stand upon which the block was sitting, and traveled an unknown distance into the polyester bullet arresting box. Bullet was recovered undeformed at 52.9gr.

Another side of the same block:

Holy S. you have all the info!

Most are manufacturer data and I have tested most of the 5.56 anyway. But the 5.45 I have to rely on what I find as I do not have it but the data is out there form manufacturer as well as other shooters with good chronys.
