Hello Members,
I am posting a link that partially shows the Ammo manufacturing operations at ELEY...It is a very long post but people who don’t know how ammo is produced, please consider reading it to the end...
Other more informed members please find the link at the bottom...
Background: Over the years I have read and heard many stories about EXTREMELY environmental controls (Temperature, humidity, etc.) inside specially designed and miracle rooms where miracle things happen with the machines producing the ammo...
Some other tales about ultra high tech very sophisticated equipment checking every single case and weighing it for giving the best consistency/ improving accuracy as well as some other kinds of equipment checking whatever you can imagine and many other fantastic stories...
I had the opportunity of visiting CCI's plant (Idaho) in the past and Eley's plant in England back in the early 80's during a tour with the ISSF management team.
The operations at ELEY and CCI are pretty much identical in regards to how the ammo is produced...The difference is that CCI is not into the Match Ammo market...
CCI has everything to produce the best ammo, but it is a profit center and its business is selling high volume of cheap and medium priced ammo... This is very understandable...
CCI produces 4 million rounds/day and ELEY 200 million rounds a year... CCI produces about 7.3 times more ammo than Eley...Eley is a much smaller plant and its operation is limited only by the capacity of their machinery...Technology wise both plants have the latest and the best equipment available and both plants use identical methods of production...
In the past around the mid 90’s, Federal (US) produced probably the best and most accurate ammo that I have ever seen... UM1 and UM2 (different velocities) .
The outstanding characteristic about this ammo is that they shot very well with almost any rifle, from cheap plinking guns to very high tech and sophisticated rifles.
Benchrest shooters used it widely with excellent results but I wasn’t into BR at the time (I was in ISSF) and I can not provide any BR personal experiences utilizing this ammo...Maybe some members reading this thread will remember and can give us an insight.
Federal’s UM ammo won many International championships and I believe they also got a Gold/ Silver at the Olympics but I couldn't validate this info at the time of this posting, so please don't take this as a fact and just understand that it was among the very best ammo produced in the world...
CCI and Federal have had the latest and best technology and equipment available but unfortunately Federal abandoned their Match ammo production for unprofitability.
Anyhow...Using this short video I wanted to show it people who don't know how .22 RF ammo is produced in order to straighten some tales and misconceptions...Mostly all ammo plants are THE SAME everywhere around the world...NO MAGIC, NO SPECIAL ROOMS, NO SECRETS heavily guarded by armed people outside of a bolt... You will see that ammo cases are all fed to machines in BULK using PLASTIC 5 gallon buckets and the Plexiglas around the machines is what people have confused in the past with magical rooms and enclosures...Nothing more than fixtures for protecting the employees feeding the machines.
Bullets are fed the very same way (in Bulk) and only the powder has a tighter control for loading the feeders for obvious reasons (Safety) ...But unfortunately this operation is not shown in this short video.
I want to point out that the weakest part in the .22 RF is the CRIMP...This is probably the factor that has more influence in consistency/accuracy...Then goes the PRIMMER compound, then the POWDER formulation and lastly the bullet design and lubrication...The bullet has very little room for improvement given the shortness of the cartridge but mainly because of the crimp limitations.
No room for boat tails...The little improvements available are in the ogive design and maybe in the alloys used for the bullet...Primmer compounds and powder mixtures are in continuos development.
The powder formulations come either from Vihtavuori or from DuPont but the former is the one mostly used by Eley, Lapua, Fiocchi and RWS...There are other smaller players but these two are the main suppliers...
I could not validate the primmer compound suppliers so I will not post this info...
About the primmer in .22 RF ammo...Keep in mind that the compound uses ABRASIVE materials to ignite the mixture because there in no anvil in this cartridge to detonate the compound as it happens in centerfire...
The abrasive compounds are SILICA based and other mixtures...
Keep this fact in mind for ALLWAYS cleaning your barrel with a WET patch first (with whatever solvent/bore cleaner you use)...
My recommendation is TO NEVER EVER use a dry patch after the gun has been fired...You don’t want to rub “Grounded Glass” layered with bullet lubricant in your barrel..
