pumpkins seemed to have worked very well in demonstrating 5.45's flipping and large exit hole.
believe it or not, try using a popcan as a test. barnaul 59gr flips before exiting the rear wall. |

Chuck, thanks for the link/info. Unfortunately it doesn't provide any insight into a bullet's performance after encountering chance barriers like wood or clothing or glass.

You think the bullet's performance will IMPROVE after penertrating a barrier
 ? That would be interesting!5.45mm Soviet's only wounding mechanism in addition to its diameter is the bullet tumbling. No fragmentation effect. Penetration is likely to be less after barrier penetration. 5.56mm is. -- Chuck |

Hey, Chuck! I think it's time you dropped that low-fiber diet!... hatLighten up, this is just an attempt to answer some "what if?" questions...

Not particularly. The performance of the 5.45 round is inferior in just about every way when compared to the 5.56mm M193/M855.

My apologies for spouting heresy in the Church of 5.56, it's apparent that rational discussion is not possible when reasonable questions are answered with the "5.56 is superior, period" mantra. If the 5.56 is so superior then there's nothing to fear from comparison testing, is there?...

How about average chrono readings? I'd like to know real velocities for different bullet weights from real AKs in 5.45.

What standards are we using? Accuracy? Penetration? We need something to penetrate.
1 inch pine boards, 1 inch apart. Wet phone books. |

Thx, Only_Hits_Count, standards are exactly what I'm trying to come up with. For the AK I'll be using a 5.45 SAR-2 w/16" bbl w/iron sights. Which AR(s)should be considered as an "equals vs equals" comparison? Obviously no optics or match/varmint setups. Someone suggested 16" AR but what about 20"? What commerical 5.56 loads would be considered M193/M855 equivelants for testing purposes? Accuracy isn't really an issue (5.56 should be more accurate, that's not an issue) but group sizes will be noted anyway during testing. One inch pine boards sound good as well as phone books behind them. Start with a single pine board and phone book then start adding additional pine boards?

LarryG, if you want to make intelligent and constructive suggestions to this thread then please do so.
If you have to view everything from a "us vs them" perspective then please go rant somewhere else. I, for one, consider the 5.56 to have superior ballistics to the 5.45 . However, that doesn't mean I'm not curious as to how the 5.56 & 5.45 military loads compare in different situations, especially since true military 5.45 is rather expensive to come by. Others may be curious as well, regardless of caliber preference. Tomac |

Remind me tonight and I'll post 5.45mm chronograph data. It's on the other PC. Not that it means much, the bullet is "just another .22" like 5.56mm is at longer ranges.
Unless someone has several dozen blocks of 10% ballistic gelatin to place behind walls this will remain an academic question. We already know that pistol bullets are more effective wounding devices after wall penetration than 5.56mm Ball. -- Chuck |

Tomac, can you get hold of a SAR-3 also? I think comparing AKs to AKs in the two calibers would be useful. Velocity, accuracy should be compared. For the .223, some 55gr S. African will do or some Q3131, and then some M855 or SS109 of common availability. If you handload, I would like to know how the AK in 223 shoots 69gr and maybe even 75gr slugs. You don't need to compare the AK to an AR, we already know which is our favorite!

Tomac,
If all you have to "test" is 30 rounds, you don't have enough ammunition to do anything meaningful. Any "data" you come up with will be statistically insignificant due to the lack of a well-planned testing protocol. Just get some water jugs or something else that will give up the ghost in a spectacular way and have some fun. |

Dude you are a tool. Everything you have said is freak'n moronic. Tomac comes on here to discuss some intelligent tests that he wants to perform, and you start whining about how your caliber is better than his. Get a grip dude. -SS |

LarryG: "Tomain", that's original, I like it! Now, go outside and play, that's a good little boy...
Dave_G, I agree that 30rds isn't sufficient for a truly scientific testing. For that I'd need thousands of rds of various ammo types as well as all the various ARs w/various barrel lengths and conduct the tests under strictly controlled conditions at all significant ranges with all the barrier/target types we want to see tested. Unfortunately I don't have those kind of resources (wish I did!) I don't claim that this is scientific or will show us anything we don't already know about either caliber but am inviting suggestions to allow us to possibly look at things that haven't been looked at before or just to satisfy some idle curiousity.

Tomac: If you want some commercial ammo that is M193 spec then buy some Winchester Q3131 or Q3131A. This 'White Box' ammo will be marked as 5.56mm (not .223 as is another White Box load).

You can't test for accuracy AND penetration at the SAME time.
So- 15 rounds for accuracy;3 groups of 3 rounds each and 1 group of 5 rounds-doesn't sound like a whole lot that way, does it? That leaves 15 rounds for penetration- I'm looking for inexpensive test media that will let you recover the bullets. 3 rounds into wet phone books, 3 or 4 PB's deep! 3 rounds-wet PB's with a denim jacket & tshirt 3 rounds thru scrap piece of local wall material-sheetrock, etc with a 4X8 sheet of plywood spaced 1 foot behind 'wall' 3 rounds thru 'wall' with 4X8 plywood 10-12 feet behind 'wall' or try the wall w/ phone books behind it, but they would have to be close to 'wall' or use series of 1-inch pine boards, line them up behind one another, in 1-inch slots cut into a 2X4 or 2X6. Anyone ever heard of a 'Fackler Box'??(SP?) |

i know this is going to sound kind of stuopid, but here is what i do sometimes, i have a friend who works in the meat dept of a store here and, when they get hams, yes i said hams, the kind you just ate last week, and use them as test matter, they will IMHO, give you the closest resemblance to flesh, and hell youll definitely know what kind of penetration your getting, damn i bet the tumble of the 545 will just devastate them there hams.....snipertaz out

Someone once posted that 1/2gallon milk cartons (paper, not plastic) filled with water reasonably duplicate ballistic gellatin.

Good suggestions, thx! The wife and I are having a new house built so scrap drywall, plywood and such shouldn't be a problem. Got a source for phonebooks but might take a little time to acquire enough for all the testing. Will check with the local meat suppliers for possible sources of "old" meat as well.

wasnt it Jeff Cooper that used to use wet telephone books as a test medium in the days before ballistic gelatin. easier to procure, easier to manipulate, and not as sensative to temperature variations. i would like to suggest that the test be performed with rifles that are close to mil-spec as possible. like a bushmaster 20inch and a suitable AK clone.

DvlDog, I've got a 5.45 SAR-2 (correct bbl length, about as AK-74 as I'm going to get) and have a 5.56 AK available as well (16" bbl). Will have to see if I can beg/borrow/steal a 20" bbl AR.

for purposes of equalizing velocities and accuracy, i think a 16" ar barrel should used alongside the ak carbine.
if you are going to procure a 20" ar for the test, the rpk-74 should be the rifle matched to it. sight radii and bbl. length will affect ammunition performance characteristics. carbine vs. carbine or full length rifle vs. full length rifle would be a more accurate method of extrapolating ammo performance. |

The Fackler Box is a rectangular box made from plywood, and open on the top. Approx. dimms: 3ft long X 12 inches high & 12 inches wide. Inside the box, you line up(front to back) large Ziploc bags filled with water. You can shoot this pretty easily at 50 yds. Did that make sense?
For phone books, look for a PB 'recycling center'-AKA big yellow dumpster. Call your local phone company and ask where you can donate PB's. Unlimited supply. |
