Lethality of 5.45x39 vs. 5.56x45... - AR15.COM
2005年10月22日 · The real Russian 5.45x39 7n6 loading is 52 grains with a mild steel core with a little lead peice above it then the airspace. It's starts to yaw/tumble within 2.75 inches of peneration. With a total peneration of 20 inches. The yaw/tumble isn't velocity dependent like the fragmentation of 5.56mm.

2016年8月9日 · Plus the cost of 5.45x39 is greater than 5.56x45. Talking the 7N6. That is a fairly recent transposition, of course, but not likely to reverse direction in the future IMHO.

2003年9月11日 · 5.45x39 is an attempt to improve upon the 5.56x45. The longer bullet (nearly a full inch in length) has a hollow cavity under the tip moving the center of gravity further back causing much faster yawing upon impact than any of the other three rds.
5.45x39... Pros, cons vs. 5.56 - AR15.COM
2011年10月4日 · Good About the 5.45x39: - It's Cheap (if you don't mind steel cased & corrosive ammo) That's about it. Good about the 5.56 : - MANY MANY more options for ammo (bullet types, weights, & manufacturers) - lots of domestic production (no import issues like we've seen in the past) - full industry support (for things like magazines & bolts)

2010年3月4日 · I prefer the 7.62x39, but it's not like it totally beats the 5.56x45 or 5.45x39. The 7.62x39 does better for lethality and barrier penetration then either of those cartridges, but does not have the flat trajectory of the 5.56x45 or 5.45x39. With that said, there are cartridges out there that beat them all in the catagories I named.

2015年5月4日 · Same goes for 7.62x51, 7.62x39, 7.62x54, 5.45x39 - bullet diameter followed by case length. Comparing the brass between .223 and 5.56, I think people have found more variation between brands than .223 vs 5.56. They are NOT the same round, though. 7.62x51 vs .308 is much the same issue but I think the .308 is hotter.

2009年12月12日 · Uh, yes, the 5.45x39 mag can be used in the Bulgarian 5.56x45. You need to use the follower from Robinson arms, and shave a little off the top of magazine. They worked fine on my Saiga .223 and SLR106UR.

2007年7月1日 · If we are going to call out specific kinds of 5.56x45 ammo, then we should also call out what kind of 7.62x39 and 5.45x39 ammo--IIRC the flat-based Yugo 7.62x39 tumbled more violently and produced nasty stellate exit wounds in pig tests . . .
