Anyone else had problems with their LNL ap press throwing inconsistent powder charges?. I purchased the press new last summer and have had issues from day one even after cleaning the case activated powder drop,powder measure tube & pistol rotor at least a half dozen times with hornady oneshot dry lube as well as non-chlorinated brake parts cleaner to make sure I've removed the anti-rust tarnish film that hornady applied at the factory.
My powder problem begins when I try to run the press as a progressive
(shell in each station) then eveything goes to hell.For example I have the press set-up for 9mm using winchester 231 powder. I verify the set-up charge using a single cartridge that throws 4.2 grains consistenly validated on two different calibrated electronic scales.
Then run 20 shells through the press as a progressive and this is the results I get.......
1 4.52 gr 2 6.20 3 2.32 4 4.36 5 4.80 6 4.04 7 4.50 8 1.0 9 8.00 10 7.9 11 3.34 12 5.30 13 3.96 14 3.66 15 3.88 16 3.88 17 3.92
18 4.72 19 4.72 20 4.32
As you can see this is a big problem since the max load per the speer # 14 manual is (4.5gr) using 124 gr hp bullets.Win 231 powder meters very well and before I start loading I usually run some powdered graphite through the hopper.........I tried using a spare hornady powder dispenser as well as a RCBS with the same results.I've had hornady send me another 9mm shell plate thinking it maybe warped but it didn't help.
I'd had a few squib loads with the bullet lodged in the barrel and at this point I just don't feel confident using the press without weighing every single round :banghead:
What's worse is I purchased a hornady case feeder that sits on the floor of my reloading room because I can't use it with this press........ Anyone with any ideas what's going on I'm all ears and would appreciate any help.
