Order a magnum powder bar from Dillon. Problem solved.The only issue I have on my 550 is consistent powder throws with big charges, like over 45 grains or so. I weigh every one and trickle what is needed. Pistol and smaller rifle charges are on the nut.
You are using your Dillon past it's capabilities. I applaud you.Tool heads are set up as follows: Station 1 Body sizing die, Station Two open, Station 3 Bushing bump die, Station 4 Mandrel die.
Seating tool head: Station 1 blank, Station 2 powder drop (using a V4 to measure powder to .02 of a grain), Station 3 bullet seating.
This guy is doing it RIGHT. Armanov floated and all. The dillons are more than able to load precision, setup like this. I’m running a 750 very similar, auto trickler V4 for powder (about to try out the super trickler), but I seat my bullets on an inline with an LE Wilson.
I am a P-dog shooter so need to load lots of ammo for a trip each year, about 3000 rounds. All rounds are loaded long and then seated in a arbor press with a inline seating die the day before they are used. So evening goes like this, clean up, eat dinner, then prep rifles for an hour soak, break out ammo for the next day and seat bullets, finish barrel cleaning with JB bore paste and Kroil. Run patch of denatures alcohol thru bore, let dry and then a patch of HBN2 mixed in a slurry of alcohol. Bullets are all coated in HBN2 to reduce copper fouling and keep carbon build up down.
With 223 you can increase production with the case feeder from DAA, Case feederI have my 550's 223 toolhead set up as assembly only (powder fill, seater, factory crimp) and I do all my case prep on my single stage/hand prime. When I'm trying to build a load I throw/trickle and fill before I load them into the press.
