Bulk Reloading on the Hornandy LNL Progressive Press. Up until now, we only used a single stage press. However now that the brass suitable to work with, we will now complete the process by going on the LNL .

Hornandy Lock and Load Progressive Press
1) Station 1 – Resizing (skipped stepped because cases are already sized. Not just that, but Cartmann never full size rifle rounds on the progressive press, it causes more problems than it cures)
2) Station 2 – Priming (some don’t consider this a station as it requires no dies)
3) Station 3 – Powder Dispenser
4) Station 4 – Powder Check (to make sure cases are properly charged)
5) Station 5 – Bullet Seating
6) Station 6 – Lee Factory Crimp Die (shown as not being used here, but Cartmann now always crimp when he uses cannelured FMJ bullets).



Here Cartmann replaced the Station 4 Hornandy LNL powder check die with the RCBS powder check die. The RCBS die did not stick as much as the LNL powder check die because it is heavier, and it comes with 3 different rod heads to match calibers better. The powder check die is not really used for precision, more to let you know that the case is properly charged, or you did not double charge (which is impossible to do for rifle, but very possible for pistol).
Here, when the top of the rod (white cap) aligns with the O-ring, it means there is approximately 41.6 gr of TAC.



The components we will use for our rounds:
Bullet: Winchester 147gr FMJ
Powder: Ramshot TAC (because it meters nicely, within .2 grains)
Brass: LC (already prepped)
Primer: Wolf LR or CCI400



Primer pickup to load in the Hornandy LNL. We use the Hornandy supplied tubes to pick up primers. Notice Cartmann’s high speed Primer-Flipper-Tool (a Dixie paper plate) to get the primers right side up for pickup.



Once primer pick up tube is full, place other end of tube in the LNL then remove the cotter pin and Primers will fall right into the LNL primer tube.



Here is the primer station in action. Pull the lever and primer tube will feed the primer slide. Push the lever and you just primed the case.



Completed rounds fall into the red bin. For the first round you should confirm powder charge (before seating bullet of course) and the OAL of the round. When using Military bullets with Cannelure, Cartmann likes to load halfway to the cannelure, which is 2.79” for the Winchester 147gr bullet.



See how Factory ammo measures up for even more comparison.



404 Rounds complete! and ready for Duty.



Cartmann was watching the Pitt/WVa game and thought he would be useful by putting the rounds on stripper clips and into the ammo can.

Making Precision Match Rounds

When Cartmann was done with the stripper clips it was not even half time yet. So he thought he would make some precision match rounds using the Single Stage Press Again.

Lee Collet Neck Die -
If you are shooting your cases out of a Bolt Action Rifle, there is no need to full size the case, instead you just re-size the neck. This way you get a custom fit case for that rifle. Cartmann has found that Neck sizing is one of the single greatest improvements you can do to produce accurate rounds. Neck sizing is much easier on the brass than full sizing and does not require lube. So remember to save all your fired brass from your bolt action rifle in a particular box. Here is a pic of the Lee Collet Neck Sizing Die from Lee's site.



Cartmann uses the RCBS Chargemaster to weigh every charge. The Chargemaster is a must have, gets the precise load about 90% of the time. Every once in awhile it will be about .1-.2 grain too high because it trickled too much. .1 grains is good enough for most people, but if not, then just pour the powder back in the dispenser and put tray back on. The Chargemaster will automatically fill the tray each time an empty tray is placed on the unit. It takes about 40 seconds for the Chargemaster to fill the tray with 43.5 grains of Varget, which is faster than I can prime a case and seat a bullet.



If cost is a concern, the only option in place of a Chargemaster is to manually weigh each charge. This is very time consuming.



The better option instead of weighing every round is to use the the Lee Perfect Powder Measure ($20). It works great, but will have variances sometimes greater than +/- .04 grains because stick powders such as Varget will have inconsistent powder drops when using a volume type dispenser such as the Lee Perfect Powder Measure or the Hornady LNL. Pic of the Lee Perfect Powder Measure (From Lee's Website)



Weigh brass and bullets for consistency. Remember we are loading match ammo here so not only are the best components used, but also we make sure the best components have the same weight. Notice how the 175gr SMK’s are exactly 175gr! Actually not all of them were, this box varied in weight from 174.8 to 175.2…. good enough.



Flash Hole deburring -
The saying goes.. this tool makes your flash hole "uniform" so it will get a more consistent flash and powder burn. Normally Cartmann never deburs the flash-hole as part of his case prep. Cartmann is not sure if this tool is even needed or how much of a difference it makes. If there is a difference, he is not seeing it. When Cartmann is making precision rounds, he flash hole deburs every case with this tool, but that's only because it's a simple process and better safe than sorry right? Same goes for adding a drop of holy water to each round, not sure if helps, but better safe than sorry.



Primer Pocket Cleaning - Cartmann only cleans the primer pocket for his precision loads. Just like Flash Hole Deburring, Cartmann is not sure if Primer Pocket cleaning helps, again it's like sprinkling Holy Water, better safe than sorry.

One option to clean the flash hole, is to use the RCBS primer pocket cleaner hand tool.



Another and faster option is to use the RCBS Trim-mate. The trim-mate is a great tool to have on the bench, it comes with a motor that slow rotates 5 "heads". In addition to primer pocket cleaning, this tool can also be used to clean inside the cases (again, for the anal peep), and also an inside and outside the case chamfer after you are neck sizing.



Hornandy Concentricity Gauge Tool -
Difference in weight of powder and bullet seating has very little affect in accuracy. Inaccuracies and "Flyers" come into play when the bullet is not perfectly concentric. This tool right here not only measures concentricity (also called "runout"), but also corrects it. Cartammn was able to get all his test bullets to within .002" runout.

At the range: even though Cartmann's groups did not tighten after using this tool, it seems to work as advertise as he did not get any "flyers" with his 20 test loads. Cartmann would not recommend using this tool to correct the runout! It seems the rounds that he "corrected" caused them to have more of a chance to be flyers.

Jury is still out on this one and more testing still needed. Cartmann has not used this tool for almost 2 years so testing this tool is still on his to do list.



MCR Bullet Meplatt Trimmer -
At 100 yards, Cartmann's groups did not improve with this tool. He was told that only time he would notice is at distance. However, Cartmann is finding the wind (or luck of the wind) to play a bigger role in accuracy than this tool. One thing Cartmann can say about this tool, is it sure does put a nice looking chamfer on the hollow point bullets. So if you are into artistic bullets, than you have already spent your money well . Some guys swear by this tool. One of the precision guy Cartmann knows says we will see a difference once we go past 600 yards when wind becomes more of a factor (noticeable as in .25 MOA). Though lots of precision guys swear by this tool, Cartmann is not sold and really think it does not help much at all (but jury is still out for Cartmann).

Here is the tool, as you can see it comes in 3 pieces, a with a trimmer, an inside chamfer, and the main body that holds the bullet. On the far left, you can see Cartmann placed a bullet inside the body.



Bullets on the left are 175gr Sierra Matchkings right out of the box. The Bullets on the right are the same bullets, but trimmed with the MCR Meplatt trimming tool.



Cartmann likes to label and mark his match loads if they are sharing the same box.



Hornady LNL Quick Change Bushings Adapter -
This thing right here can convert any press with 1 1/4 -12 threads to a press that will be able to use Hornady quick change bushings. Here it is on a Lee Classic Press. No adjusting of dies ever again. Just place in, turn 1/18" turn and the already adjusted die locks into place at the exact same position it was set at before.

However, Cartmann has since ditched this conversion bushing and replaced with the standard threads + Hornady Lockrings, reason is a full size die will frequently come loose with this bushing. Hornady lockrings also works great, no adjustment of dies again, but most importantly is the lockring on the die allows the die to stay put, something the Die Busing Adapter could not do.



Reloading gets messy, so now it is time to cleanup using a portable shop vac, a paint brush, and a oil rag to wipe everything down.



The Cartmann man room is all cleaned and ready to be used for the next time
