RG chrono results: and comparisons to other MilSurp

Sumoj275 · June 27, 2001, 18:57

Picked up some Radway Green ammo and had problems in three rifles. Two were Century L1A1, one never has had trouble with SA, and the other L1A1 was new. Also did not function very well in DSA Carbine, SA has worked fine before. Is it me or does it seem to be less consistent, and weaker? Made he day a little rough considering that was the only ammo there. Going to try some other stuff this week and see about it. Just wondering if anyone has had any experiences with it.

BTW, when did get to function it was on 1.

Thanks

I have fired close to two thousand rounds (85-89 Mfr. dates)of it without so much as a hiccup or a stutter. It has always been reliable and consistent from my perspective. There is always the chance that ammo from that lot may be the problem. Being surplus it could be and is most likely attributable to storage conditions. Hard to say without benefit of testing.

Jim

Hey Sumo,
I have shot a lot of Radway and found it to function fine. I think velocity is down a little and it is not as clean as Hirtenberger or even SA, but if a rifle functions with other NATO ammo, it should with radway also. I have 5 cans of 84 manufacture Radway which is supposed to be questionable, but the 6th can gave me no problems. As far as consistency, I have been pleasantly surprised by accuracy in a couple FALs, but have not ran any thru a chrono to verify consistancy. While I would not rate it as great, I have not seen anything that would give me reason not to buy more (when the price is right). Consistancy has (so far) not been a problem. The powder is not as clean as some. My .02

Mr Clean · June 28, 2001, 09:49

I have been shooting the ammo in my STG kit
rifle, and I find I must set the gas at 3.5
in order for this to function. I made some
hand loads - 147 gr FN bullet & 42 grs of AA2520 and the gun shoots at 4 or 4.5.
Otherwaise, the Radway shoots fine. John

Charmedlyfe · June 29, 2001, 23:59

I've got some 88 RG, and in my DSA carbine it won't extract on fully-closed. Denel 99manuf. gives no problem. UMC works.

stargazer · July 01, 2001, 05:23

I've had (2) failures to extract using RG. All other ammo so far has had no problems. Using Entreprise Scout Carbine. Not much more "RG" to get rid of. Seems too light a load and dirty burning powder. It works in my rifle "most" of the time, but I will choose another brand in the future. Glad I only had 200 rds. of it.

So is the RG the benchmark, or is your handload the benchmark? Are you using too much AA? Have you compared MV of each on the same day, same time, same weather.

For ALL you contributors on this thread-

Let's add some meat to the discussion.
- Year of Manufacture (YoM)?
- Other benchmarked Surplus ammunitions, and their YoM
- Sources
- other facts AND observations

Dirty is a good observation. Low report is a good observation. MV is a great observation. 1979 vice 1991 is a great observation. Sealed tins vs. loose pack vs. cardboard boxes in open tray is a great observation.

I just want to narrow down and eliminate the intangibles. I'm not saying you aren't observing the symptoms you guys note, but help us gather the ammunition 'data' a bit, will you.

BTW- comparing handloads to brand new milSurp (liberated MG stock from a certain 70t weapons carrier is my favorite benchmark) is like comparing apples and oranges. Nice to know, but we still don't 'know jack' (Paul Reuben where are you?).

Comparing MilSurps is a bit tricky, and old MilSurp is likely to have a spotty logistics bibliography or resume.

Choose wisely grasshopper.

Grinder · July 01, 2001, 12:23

Now you guys did it. I'm going to have to getout my chrono this week and set up a test shoot. I have British + RG89, Israeli TZ80,
Spanish 7.62X51 SB78, Argentine 7.62X51 01FLB83, Portugese + FNM 76-31. The rifle will be a std. length STG on Imbel. The rifle will run on a "5" gas setting. It should give a good baseline for surplus velocity specs. I will leave the rifle on that setting for all ammo. Any specific requests? No accuracy testing please due to time and open sights

. Maybe I'll run them through my FMP XG3S also.

**EMDII** · July 01, 2001, 12:36

Now you're talking. We need MV and SD, along w/ the spread, for at least 10 rounds of each kind, 20 if your budget allows.

**BUFF** · July 01, 2001, 16:13

One of the beauties of the FAL design is the adjustable gas system.

I have my L1A1 set up to cycle on RG, have shot up a bunch from three or four different headstamp years and lots. Never had a problem, and I like it a lot. It should work, my L1A1 is Enfield except for the Entreprise receiver. Gun and the ammo it was made to shoot!

I know some other types of ammo need a bit less gas to cycle reliably, but so what. Velocity has not been subpar with the RG, so if I can get the same velocity at what appears to be less pressure, to me that is a good thing.

When I shoot milsurp, I have a simple system or practice that works for me. I try to buy 1,000 rounds or a case at a time. I open a lot or batch of ammo, and zero and adjust the gas system if need be for that lot of ammo. I then shoot it all up unless I try something else, and then set up the rifle for the next lot or case of ammo, unless it is the same lot purchased at the same time from the same dealer. 1,000 rounds lasts me an outing or six. When I find ammo my rifle likes, I try to buy what I can afford, rather than buy a bit of this and a bit of that.

Oddly, my new DSA STG likes Hirtenberger!

Grinder · July 02, 2001, 21:19

My chrono will only do 5 at a time and calculate. Figuring 20 shots will be easy for average and extreme spread, but what about SD? Someone have the formula handy?
I only have 15 rds. of the Argentine, but 20s will be OK for the rest.

dan · July 02, 2001, 23:08

I have had problems with the radway green in stg 58 rifle. the emhty shell case would fail to excract . but works fine with fn ammo.

Did you readjust your gas system when selecting the RG?

The FIRST cause of FTX malfunctions is incorrectly adjusted gas system.

Just give the break on each 5-round set. That'll give everyone an intuitive feel for SD.

Finally got a chance to chrony my 84 RG and here are the results.

1st 5 rnd group AVG 2784.2 SD 12.6
2nd 5 rnd group AVG 2759.8 SD 9.6

The 2nd group was fired after I had shot 8- 5 rnd groups of reloads.

I was using a CED chrony which I know is on the money for calibration.

Fired thru a Stg

Have read some posts about this brand being a little light and the 84 stuff having problems.

Thats kewl! Have had no probs with RG89 with Fal or M1A1 so the reports of low power were puzzling. This thread would be good for the FAQs, subject gonna come up again

ricochet · July 04, 2001, 20:03

Good info guys,
I just got back in from the range and tried a little testing,altho nothing like yours. I shot my old eggbeater R1/Imbel, a kitbuy Imbel/Imbel, an Entreprise Gov't, and my newest build a British L1A1/Entreprise. I carried RG84, RG87, Hirt89, and DAG85. To make a long story short, it all functioned fine except the RG'S. The R1 and Entreprise Gov't will eat anything and are happy. The Imbel/Imbel did fine once I threw the POS Century hammer in the woods and put an EAI back in it's place. The L1A1 would only function with the Hirt and DAG, and only spotty at best. It didn't like it's own ammo worth a crap. All did seem to function best with the gas open more on DAG and Hirt, close off a little for the RG. And the RG does seem to burn dirtier, but it grouped, for me, the best. The little R1 Frankenfal was putting little clusters at 50 yards with RG, and about 1-1/4" with both the Hirt and DAG.
So my data is seat'o the pants stuff compared to this other stuff you guys did, I can see that some like some ammo better and that there was a functioning difference with the RG. That said, I'll still gladly buy RG, but also gotta work on that British L1A1.
Together with you guys, I am learning. And the Century hammers are not the place to save money. Overall I had a good 4th (after working my 12 hour day). I had my own fireworks

thanks to our forefathers...

ricochet · July 07, 2001, 21:25

Guys,
When I said "good info guys", I meant yours, not my simple function tests. I didn't mean to kill a good, informative group of posts. My stuff was merely a function difference that I found that day. I was surprised by my results, and am glad your chrono tests show RG to have more velocity with lower pressure (my guess).
Keep it coming

Grinder · July 08, 2001, 13:53

Hey, I ran out of ammo

Seriously, I only showed my batch of RG 89 was up to snuff. I would like members to chono the lots/ years which are showing signs of being underpowered and report. If you don't have a chrono, buy one or have someone else test in.

I have never had any problems with RG, but it seems that the Port and Hirten' are cleaner. Also would like to have info on the Malaysian surplus(chrono data). It has been very consistent for me. Gotta get a new chrono!

Not being a Chrony guru what does "ES" stand for? And I guessed "SD" is standard deviation?
Thanks!

PS what happened to that second batch of Argentine Ammo? Kinda strange numbers.

Grinder · July 10, 2001, 22:38

ES is extreme spread. The highest velocity minus the lowest. I was surprised at that group of Argentine also. Unfortunately, I only had 1 box I traded for for testing. I would have liked to try more. That is why 1 group means very little in accuracy or ballistics testing. It can look a lot better than the average you are really going to see day in and day out.

Pretty neat info you guys have collected. this report becomes a keeper! __________________ "The Spartans do not enquire how many enemy there are. The SPartans merely enquire WHERE they are." E.M.

Save your data in the field and download and save as a spreadsheet at home. I believe one of these outfits include the pc cable and a spare set of skyscreens. A spare set of sceens real handy in case ya happen to ping one, like I did once. (always carry ductape)

TF PS what happened to that second batch of Argentine Ammo? Kinda strange numbers. __________________ Tenderfoot Will work for brass,steel,lead,iron,wood,powder and etc.

Unfortunately, I only had 1 box I traded for for testing. I would have liked to try more. That is why 1 group means very little in accuracy or ballistics testing. It can look a lot better than the average you are really going to see day in and day out.
