I am debating getting a LNL AP and have heard a lot of good and bad about them. I was just wondering what the cons of this press are? And if I can use my lee and rcbs dies with it?
I think there stuff is expensive ...
I appreciate the detailed fix list for the problems I listed. The LNL was my first progressive press and I still have it on the bench, but it is no longer used for any volume caliber. The OP asked for a list of CONS, and I listed the ones I encountered to the best of my recollection, even though I was reasonably satisfied with my press for some time, and only switch to another because Hornady was unable to solve my priming issues. Many issues as you know have fixes, but not all will be easily diagnosed and addressed due to tolerance stack and other issues between presses. The mgf. tolerance control is not as tight as it could or should be coming from wherever Hornady has the machining done on the LNL.1.) Primer seating stem lacks leverage, and on some presses, will not seat primers reliably no matter the fix tried
If you're having problems with this, you don't have the primer mechanism polished and adjusted properly so the primer is coming in centered over the punch/under the primer pocket. To properly polish and adjust the primer feed mechanism, you need to polish all the rough parts (not a lot of work) and adjust the primer indexing bar in the X, Y and Z orientations so the primer pick up hole on the carry arm is centered perfect under the drop tube when in the "back" position and the indexing/timing cam rod is oriented so the primer carry arm is traveling straight and parallel in it's trough. During this process, you need to blue loctite the nut underneath the press and the screw holding the plastic piece at the top of the indexing/cam bar. Once that's done, your primers will be situated to seat properly. Once that's done, your primers will will feed properly and seat properly from now on, as you've got the adjustments correct and loctited in. To insure the last primer(s) in the tube feed, add a brass or other material rod above the primers to simulate the weight of a full tube of primers. If you use a thin enough rod, the rod will slip into the primer carry arm hole and "lock up" the primer carry arm, preventing it's travel and letting you know you're out of primers.
If, at that point, the primers are still not seating to the proper depth, it can only be one thing - how far the primer shaft is coming up. If the primer shaft is not coming up enough, it can be shimmed (I've never had to do this.) by placing and glueing/tapping/drilling/screwing in a small metal shim or adjustable screw underneath the primer punch mechanism.
If this does not resolve the issue, your primer punch is of an improper length and needs to be replaced. Of course, if this is the case, the primer punch mechanism needs to be replaced with a primer punch mechanism where the seating punch is of the proper length. Doing this eliminates the need for the mod mentioned in the previous paragraph.
2.) Primer slider will bind and stick if not perfectly clean
If properly polished and adjusted, this is pretty much a non-issue. With the primer mechanism polished and properly adjusted, the amount of powder/dirt needed to cause the primer mechanism to hang up is likely the operator having an improperly adjusted press in many areas, there by making many other errors/mistakes, spilling lots of powder and failing to clean up the spills, then failing to take the time to polish, properly adjusting their press's operating mechanisms and failing to learn how to operate their press in general.
Most complaints I've seen of the Hornady LnL are by folks who owned a different brand of progressive previously and didn't take the time to get to know and learn their new and different LnL like they did their other progressive press when they first got it. They also allowed themselves to blame the press for their lack of diligence in learning their new press. The Hornady is auto advance, a different mechanism/operating mechanism and requires a learning curve.
It seems odd, but is true, but those that have the most problems and dissatisfaction with new progressives tend to be those coming from a different brand or progressive to a new and different one. I include myself among these folks. The important point is to realize one may be among this group and to take the time to learn how the mechanisms of the new press work, how to adjust/tune those mechanisms and how to properly operate the new press.
If one doesn't do this, dissatisfaction is sure to occur.
3.) Lack of decent roller handle compared to a Dillon
Very high quality, better than the Dillon roller handles are commonly available from several aftermarket sources. The Dillon roller handle will fit with very minor tweaks, but why do so when these excellent aftermarket handles are available.
A mistake many press owners make is wanting to buy or source all their reloading equipment from one manufacturer/supplier. This limits what one can get as well as limiting the variety and over all quality of the reloading experience. All the companies out there have good stuff. Once can improve it greatly by mixing and matching.
4.) Die bushings will back out, Hornady will supply shims; they still back out
In a decade of buying Hornady die bushings, I never had a single one back out. If they do back out of some press, it is likely not the die bushing, but the tolerance between the bushing and the bushing receptacle that is the problem. The press should be returned to Hornady for replacement of the die bushing receptacles or Hornady should send out new receptacles.
A simple tolerance/manufacturing issue, easily resolved. One should not accept a bandaid like shims to resolve a manufacturing defect.
5.) Case feeder is an afterthought with many design flaws:
Unlike the Dillon casefeeder, the Hornady case feeder is designed to feed both rifle and pistol cartridges and comes with all the parts to feed many calibers. Because of this, it is not an easy mechanism to adjust because the variety of available parts and Hornady's granted "needs improvement" documentation doesn't explain it well.
To get it to feed properly, the operator should first have a properly adjusted and smoothly running press before attempting to add the feeder.
a.) 9mm will fly off the platform
Only if the feeder is improperly adjusted or the wrong feet/etc. are used.
b.) cases will get caught at the top of the case feed wheel and bind
This is a known design flaw and the fix is available with excellent pictures. The name of the forum escapes me at the moment, but it's a simple fix and with a minor tweak, the problem is eliminated. Shouldn't be there, but there case feeder is a fairly new product for Hornady. Dillon had many renditions of their press before finally settling into the "not perfect either" presses they offer currently and even these presses have had modifications over the years to improve some aspect or problem found in the field.
c.) cases will get caught in the case feed funnel and jam
Not if you've got it setup right and using the correct tunnels. In some calibers such as .40 S&W, one may have to fabricate or get fabricate some adapter parts to get better tolerance between case and case tunnel. Unfortunately, this is where having a case feeder that is designed to feed everything rather than selling caliber conversions for each caliber can cause problems. But the solution isn't a difficult one to come up with.
d.) cases will fly out of the case feed and hit you in the head
If one is slamming one's press around enough to get cases popping out at that velocity, one might consider rethinking how one is operating one's press. Remember, the main object of any reloading press is to produce improved ammunition over what the factory offers. This is true even when one is reloading progressively. If one is slamming one's press around in an attempt to get speed, one probably isn't reloading quality ammunition.
e.) 9mm will not feed into the shell plate without tipping, Hornady sends replacement shell plates but they do not completely solve the problem
This is an adjustment problem and the cause is likely the wrong feed foot. Improperly adjusted press with off time indexing contributes greatly to this problem.
f.) 9mm will not feed into the shell plate fully using the supplied v block
Try another v block, you may be using the wrong one. Hornady's instructions aren't always clear. Additionally, your press timing/auto advance can affect this, as well as the adjustment of your case feeder's cam rods.
g.) cases will bind in the drop feed mechanism
Again, an adjustment, tuning and tweaking issue. Take the time to figure it out. Once you've come to understand the mechanism, polish/tune it up and loctite the permanent parts down, most of these type issues are gone permanetly.
h.) cases will get stuck at the junction of the funnel and drop tube
Again, tune, adjust and tweak. Learn the mechanism.
i.) will not work reliably in any combination with .40 S&W
A known fix with pictures has been posted on this board. To get a feeder that works with all available calibers, you have to pay for "caliber conversions." Again, the Hornady is made to be "once size fits all," but when you buy it, you have to realize it's going to need tuning/adjustment/tweaks. Even mechanism designed to feed a specific cartridges are going to need tuning/proper adjustment/tweaks, so you aren't missing much. At some point, Hornady engineering will likely resolve some of these caliber type issues, but until then and while the feeder is still new, it is going to need some home made resolution.
Since Hornady did made engineering tweaks on the Hornady Projector to improve it to the Hornady LnL, it is reasonable to expect they'll continue to improve their product line. See Dillon history, 300/350 to 550 for an example of this.
6.) 9mm will not eject 100% reliably with EZ eject
Polish the shell plate, properly adjust the auto indexing for smoother operation. Blue loctite pawl screws.
7.) Index pawls will round off and press will no longer index consistently, which is a hard problem to diagnose
Take the time to learn how to adjust the indexing (does take a bit of time, proportional to one's mechanical aptitude, but most folks can resolve this issue permanetly) by carefully going through the auto advance mechanism until the shell plate rotates smoothly and locks into it's detent ball locations without "bounce."
8.) Shell plate bolt will back out if not tightened down tightly, but when tightened down tightly, cases will not eject reliably
This is a tolerance issue and I'm not sure the EzJect nub is the final solution. Modifying the press to eliminate the ezject nub (file it off) and adding an RCBS style ejector (L shaped spring wire with a small set screw mounted in the base plate) may be a better solution. This would not be a hugely difficult modification and would resolve all ejection issues.
I still do not understand why Hornady eliminated the effective ejection mechanism on the Projector, except it may have been a cost reduction effort on the part of the bean counters.
The drop tube is not long enough for the short 9mm case to prevent it falling off the side after dropping down to the sub plate. Modification needs to be made to the drop tube to make it longer so the case is unable to fly off. I used PVC tubing, based on a tip off another forum to extend my drop tube to the necessary length.
not all will be easily diagnosed and addressed due to tolerance stack and other issues between presses. The mgf. tolerance control is not as tight as it could or should be coming from wherever Hornady has the machining done on the LNL.
Two words for that problem: Teflon tape, a few winds around the LNL bushing will fix that.The LNL bushing for the powder measure backs out and comes loose.
