Very sunny Sennybrige today ( 4 AR's present On G Range using (aprox 120 rnds)RORG 92 and could hit everything out to the guy in the window every time (400m I think ) I was extremely happy with my Scopeye M4gery Changed to RG 04 and could not hit him at all.... ![]() Why? Dirty gun Hot gun Me Ammo Anyone got any pointers? Cheers Taffy Was a great day shooting in the sun but the last box of ammo left me confused. |
If that's correct and I've no reason to doubt you then that explains everything...cheers I spoke to someone at the range today who claimed it was the same ammo to same spec and doubted him only because of my results. Thanks Mark Taffy ETA do we have a chart of year of manufacture with differences in ammo |
I hear you . cant dissagree but in these matters I have to defer to those in the know. As this change in RG 5.56 I was not aware of before so God forbid there could be more that I do not know. Don't tell my wife..Taffy |

Hey Tafffy I was on F range at Senny today, weather was indeed awesome I was using '92 vintage RG through the 14.5 carbine & 20" rifle today. Both got consistent hits on the 600m ETR before its battery went flat.... I chrono'd the 1992 stuff earlier this year. M4 - 2950fps 20" - 3150fps Cheers Steven ETA I'll chrono the 04 stuff next chance I get. |

The info in this post is of great interest to me, as I didn't know of the differences Thanks for posting Taffy I managed to make a twat of myself today by taking my 223 PSS with my 308 PSS bolt, Did manage 3rd in our mini rifle comp with the 20' AR and Ciener conversion though Topped the day of with going to see Paddy McGuiness live last night Recomended |
I once got to the range and realised I'd left the keys to the gun case at home, shit happens. Human nature to make mistakes, and some of us are very human Tony |
Well that's better than getting to your cabinet and realising your 700 is still on the point at Bisley |
3150 fps is a little high for RG, the spec sheet quotes just over 3000 fps. From a short barrelled M4 your 2950 seems even more optimistic but there are many variables that can effect chrono measurements. It must also be understood that a chrono available to the average shooter is not a precision scientific instrument and should not be treated as such. |
Yeah, fair one. I'm just looking at the spreadsheet now & I was wrong about the M4 velocities I quoted earlier. That day I measured an average of 2900, not 2950. FWIW 7.62 RG Bisley 'match' averaged 2800fps from my Sako TRG. Cheers Steven |

I've always found RG of all batches I've tried to be OK but there can be the occasional (1 in 10) hard extraction. However, fired 100 rds of RUAG the other evening through my AR, most impressed - no extraction problems at all & very consistant - preferable to RG in a straight pull. I'm a convert, which is annoying... |
|
exactly - v annoying! |
Where can we get some RUAG from
|
Remind you of anything, Mark? ![]() Glad to hearthe rifle is still going well, Taffy. About time you went for a new barrel, isn't it? |
Oh yes, yes indeed I also remember once me and thee setting off for Wareham and only remembering as we passed the Bisley turn-off on the M3 that I'd forgotten my ammo, and us making a hasty detour to Bisley to buy a can of RG |
lol, Wasn't that the same time we went the wrong way on the M27 and wondered why the sun was coming up in front of us and not behind? |
No that was a different day
