Why would they not continue to offer the APS/primer tube choice in the new Pro Chucker Progressive press. They would have given their APS base something to graduate to and in the same time increase the customer base from primer tube traditionalists. Who knows, at some point they might have left the dark side of the force and tried APS.
The why is simple. Tube users are the majority. Because RCBS wouldn't share the APS technology, all the competition, blue & red, pooh-poohed the technology. Most new progressive customers listened, rather than trying out the new system for themselves. No matter how much APS customers raved, the numbers weren't enough to create the sales & market share that RCBS wanted for it.
The blame is totally on RCBS! They refused to put serious money into marketing a new technology....word of mouth is not enough....nor did it help to alienate all the competition..
So....they let their engineers loose to build a new progressive system. When they looked up, they found that they were designed to be tube-fed only. Only then did RCBS brass ask the engineers to make an APS option. Engineering said no, they'd have to start over. You see, you can make an APS design feed tubes, but not the other way around. On the new presses, the primer shuttle is
aimed directly at the ram. With APS it needs to be aimed
beside the ram so the empties come out the other end. Pure and simple......and stupid on their part.
So if you want nothing to do with tube priming you have two choices, hand prime or buy the Pro 2000 and APS primers and/or strips while you still can. The only cast iron progressive other than the Dillon 1050 will last 2 lifetimes at least. APS strips too if you take care of them.
APS strip longevity tricks: Store strips flat so they don't get a bend, and don't force them to feed and end up mangling them. When the occasional high primer anvil happens to protrude enough to stop advancement in the press, just pushing the high primer down a tad with a primer-sized rod, dowel, allen wrench or whatever, puts it back on line. You won't have that problem if you rub or roll something over all your stips, several strips at a time, (anvil up) before you mount them to the press. I used a wall paper roller before I modded my strip loader to do it automatically.
