My oh my. I go TDY for a couple of weeks and all hell breaks lose in the WT. Let me put some light of the subject for ya! First this pup of a weapons troop, "Load Toad".
<BLOCKQUOTE id=quote><font size=1 face="Verdana, Arial, Helvetica" id=quote>quote:<hr height=1 noshade id=quote> In regards to "Ammo Splicing." It's not allowed. It hasn't been for quite some time. The UALS come preloaded to us Weapons troops straight from Ammo, and we are only authorized to put those rounds into the jet. According to the TOs and AFIs, that's the way it's supposed to work. That's not to say that sometimes it doesn't happen like that, but personally I've never seen it before.
Now I may be mistaken about this because I've only worked on F-15's before, but I know that if your ammo comes from a UAL like ours does, splicing is not authorized. If you disect a gun system, and look at the "last round switch" inside you'd understand why. Cycling the gun system (as is necesarry when swapping UALS) leaves at least one or two empty elements in the system. Once these empty slots hit the last round switch, the gun system stops spinning to prevent a gun jam

My dear youngster weapons toad there are absoulutey no simularities between the UALS used for 20MM loading and the GFU-7. Ammo does not come from the MSA already in the loader. Read your CDC's. Splicing is exactly what the 2 and 3 man do during an ammo load. The CIU of the ALA is connected to the CNU cans. The 30mm rounds are in LTC's which are linked by "ties". The 2 and 3 man have to splice the LTC's from the CNU to the ones on the ALA with these ties. You load 575rds from one can and stop. Move the CIU to the next can and splice onto that belt of ammo and start again. While this is happening your spent brass is going into LTC's and back into the can you just loaded out of. By the the knucklehead that said we reload 30mm shells is wrong. The spent aluminum cases are turned it for recycling not reloading. If he seen a shell that said 1975 or whatever it was surplus that was finally expended.
When the A-10 first came out it could hold 1350 rds of ammo. The problem was the inner drum, "Helix", was to fragile and needed to be beefed up. GE did this but the trade off was less capacity. The system then could only hold 1174. Yes that is a weird number but that is correct. Of course you have you plus or minus in there.
Now for the combat mix controversy. I loaded tons of the crap in DS ONE and to tell the truth I cannot remember if it was 4:1 or 5:1. I do know that ammo troops process the stuff and per their TO's set the ratio. We also loaded loads of all HEI for CSAR missions during the storm.
One last thing for Toad. The last rds switch is not to prevent jams. It is for what is says. Last rd is detected, counts a predetermined number of elements and shuts the gun down.
Oh by the way my credentials for GAU-8/a gun system knowledge are this. Gun backshop, RAF Bentwaters 82-85, Gun Shop, Myrtle Beach AFB 85-86. Weapons Maintenance/Load Crew Chief, Hot Gun Super MB AFB 87-92. Same at Shaw 92-95. Attended every FTD available during that time frame for gun system. Was also Ammo augmentee at Bentwaters. Processed ammo and built up bombs during Phase II exercises.

Hands clear. All switches off, safe or normal. Gun hot or cold? No limit, you bet.
