It's time I chimed back in on this thread. I'll add a few comments about how I use my XL 650.
I don't bother with the standard dillon measure for rifle loading. I use a Hornady case activated measure for all rifle loading.
For shells that have been trimmed the loading before, they get checked for case length. If they're not too long they go through the entire process, station 1 through 5. Since I don't crimp .223, theres no need for exact case length.
So that puts me in league with others that use the best parts of both worlds.
For pistol, I find the dillon sliding bar type measure adequate for my loads. Most are shot very quickly at short range into a silhouette for IDPA or IPSC.
I suspect if Hornady would ever come out with the AP WITHOUT those @%*! LNL bushings, I would buy one! I've just seen too many threads here and on other forums about the poor quality of those inserts/collars/bushings. People claim that they NEED the quick change feature. Then say nothing about whether they hold the dies as well as the dillon tool head. By "as well" I mean has anyone done any runout measurements, Hornady versus Dillon? If the tolerances that Hornady holds is so far off as to allow bad bushings to get sold, causing powder measures to loosen up, then how would they hold a die straight and square?
If the top of the Hornady was tapped 7/8X14 so you could thread dies into it, I suspect it could out do the Dillon 650 for runout measurements.That only leaves the shell plate/ram to hold the shell solid.
I guess I get defensive about my choice for loaders. If I hurt any feelings, then I'm sorry. But I naturally have to call a spade a spade, sometimes I get carried away!
