Re: Dillon for match grade ammo

Certainly, good matchgrade stuff can be built on a progressive. The number one issue with the Dillon is the sloppy fit between the tool head and the press. This results in varying OAL's. You can make pretty accurate ammo even with some relatively high concentricities. However, if you have variance in OAL causing some bullets to be jammed and some to be jumped or forcing you to seat way away from the lands to avoid this, you don't have ammo as good as a single stage.
Also, if you have variances of a tenth of a grain of powder or more, you don't have ammo that is as good as handmade. These things can be achieved on a progressive with a few modifications as YAOG mentions above.
I am not usually a fan of learning to walk before you learn to run, but I actually think that a beginner should learn on a single stage and measure everything often. Once you get this down, you can learn to use a progressive to great effect.
You can buy a 550 and use it basically as a single stage. OR you can start on a single stage and buy a 650. Personally, I don't see the point of having a progressive without having auto indexing.
BTW, if you do get the 650, you will need to fix the indexing so it does not index as hard. I don't see why they didn't fix this from the get go. The fix is very simple. </div></div>
Carter,
Yes, I have been using various versions of the Whidden toolheads for quite some time now. What made everything really come together for me was when Redding released the Redding Instant Comparator I bought it on sight. The Redding Instant Comparator overnight allowed me to control shoulder and ogive to the point that every finished round is essentially mechanically identical.
I no longer just blindly bump case shoulders back a certain amount like most folks suggest. I double neck size with a FL size on the second necking. Every shoulder measures the same height from base to datum line and I can measure it to confirm during processing! This came about as I developed my loading workflow and killed one by one the limitations of the Dillon 550 on precision case processing.
