Hornady Lock-N-Load AP looks like a nice piece of kit.
Not the full-blown Ammo Plant, just the basic progressive.
In the videos, it looks like it runs smooth with that 1/2 and 1/2 index feature.
So I realized I haven't read much about crimping,I've looked thru the books and I feel like I'm missing something or not reading it right.it just says how to get a light or heavy crimp,I don't see any info on the loading data either.so how do I figure out what kind of crimp I need,where to put it and if I did it right?
You can have flush primers but they are not seated all the way in. I recently had some Fail to Fires, where the firing pin struck the primer but only pushed the primer in all the way. They had been flush.
Yeah, it looks like you get A LOT for your money with that one...best deal for a progressive, looks like to me.I just picked up a LNL and loaded my first 350 rounds in about an hour. There are a series of videos available via youtube on hints and tricks for the LNL that I watched before setting mine up. I didn't have a single misfeed, powder issue, or alignment problem. I know everyone raves over the Dillons, and they are no doubt very good, but so far so is the Hornady LNL and for a lot less dough.
I thought he was clear on the difference between roll crimp and taper crimp.45ACP Crimp(?)
The crimps pictured are for a revolver round that head spaces on the rim, NOT a 45acp, and do not apply here.

Great post, @Dyjital ! That is a beautiful example of a roll crimp.When it comes to crimping...
The below image shows just how little crimp and belling is needed. I created this a while back for my Instagram account to show the differences in the steps.
The rounds shown are .357 Magnum and use roll crimp and not taper crimp. The concept is the same though with amount of flare and crimp. Overdoing case flare/belling will result in cracked cases and overworking the mouth of the case leading to cracking when fired. The idea is to use 'just enough' to get what you need done without going overboard.
#1: case unmodified
#2: case with bell/flare added so Bullets starts to seat properly
#3: bullet should sit inside case a little bit. On this setup the bullet is actually nested .110" inside the case.
#4: bullet seated to near proper depth. Because the die crimps AND seats the bullet you cannot fully seat without crimping in one step, that's why it's not fully seated.
#5: seated to proper depth and enough crimp is added to remove the earlier case belling as seen in photo #4 & #3. The top of the ram is where the die is dialed in for the crimp and seating

With your .45 you have a taper crimp. The taper crimp ends up doing similar but no roll in at the very top of the brass as seen below:

Your dies manual has a LOT of this information and how to set your dies up to deliver perfect crimp every.single.time. Believe it or not they (die instructions) will be invaluable at this step.
I may do one in .40 or 9mm down the road for comparison.
I never thought of a revolver as having any headspace at all.45ACP Crimp(?)
45acp is not really crimped as much as "de-flared" as it head spaces on the front edge of the case.
The "press fit" of the bullet into the expanded case holds the bullet in place, NOT any crimp.
The amount of "de-flare" is a diameter that is the sum of the bullet diameter plus 2x the case wall thickness measured at the case mouth of a completed round.
Going smaller will only deform the bullet.
Of course you should always do the plunk test too.

Your receipt plus the order form off their web site (get loaded). They also have it that you get 100 bullets if you buy a die set.Yeah, it looks like you get A LOT for your money with that one...best deal for a progressive, looks like to me.
And with the current promo you get 500 free bullets. Deduct that value and you're right around the cost of a Lee.
Did you get a certificate or something for those free bullets ?

On the cartridge drawing there is a measurement at the mouth of the case. In this case it is .473 for 45 auto. After you crimp measure the case mouth with calipers. .45 auto usually crimps between .473 to .470. That is about where you want to be so the case mouth headspaces in the chamber properly.

Lee Factory Crimp die.Most semi auto rounds have enough taper on the inside to hold bullets in pretty well through neck tension. A slight taper crimp removes any bell, seals the case mouth, and is extra insurance against bullets moving. The factory crimp die will give you instructions on how to adjust it properly, just a little is all that's needed.
Lee Factory Crimp die.
I don't have one, but I know that they are very popular.
What is the finished product difference between the LFC die and a taper crimp die ?
