I bought a MEC 600 JR in 1976 for about $60 new. I've loaded approximately 25,000 shells on it and it still works like new. The head of the bolt that pushes the shell back out of the sizer is badly rounded off but that doesn't affect function at all. Great machine for a hunter.
I have had and used 3 of these machines for many, many years now, and never unhappy with the wonderful, factory like results. This machine may take a bit of getting used to for the crimp settings, but due to it being almost, "too simple". My crimps, both 6 & 8 look as good or better than the factory rounds on all of my 2 3/4" & 3" loads. The other wonderful function of this simple, inexpensive unit is that of being able to "feel" your shot load and wand compress. I also load my Lee cast 1 oz. slugs in this machine with the greatest of ease, using multiple brands of 12 gauge hulls. I can't imagine any shotgun shooter without a MEC 600 Jr .
I'm about 3 weeks into the learning curve on my Mec 600 Jr, Mk 5 in 410 bore. The machine is very well built, easy to understand and easy to use. I've made about 200 rounds so far with no hitches whatsoever. All I needed to add were reloading supplies and a good reloading book. And for sure, there a significant cost savings when reloading 410 bore.

I have 5 of these and they are awesome machines! Behind every great progressive loader is a mec junior to fix the screw up! Great product at a great price and even better customer service!
I have had a 600 Mark V for a number of years. I also have a PW machine as well. I recently added a new gage to the 600 (16 gage). The final crimp on station V rod stem threads on the machine were inoperative as I could not thread the stem so as to attach the final crimp cylinder on to the bracket. Luckily I had a 5/16 x24 tap to rerun the threads. Worked great after that. The MEC machine is a lot easier to unload the components (shot, powder) . Tilt it back put the caps on the bottles and store them away. The MEC does make a better crimp than the PW.
Thank you for taking the time to comment. The threads in the turret head may have been a little rough for the crimp punch. It was a good idea to tap the hole for the new punch. You can email and call us directly if you have any further comments or questions. 800-797-4632 or reloadersales@mecoutdoors.com .
My dad bought he’s Mec jr when he was 14 years old ,he’s now 70 years old. I grew up using this press and stile continue to use it to this day and now my son is using it with me the old girl stile makes a great reload , I need to freshen it up a little and get some different size powder bushings . One of the best presses ever for a working man
EXCELLENT video. Thank you for showing me how easy it is to reload with the MEC 600 JR Mark V. 12 gauge is plentiful to find, but feeding my several .410 bore tools is challenging. I just wish MEC would sell the .410 reloader with apparatus to reload 3” AND 2.5” shotshells. An additional $199.99 seems like a whole lot to require for the ability to shoot both versions of the same bore, particularly when no additional fee is required for 12 gauge 2.75” and 3”. Grace and Peace
Hi Jun, No I'm sorry we do not have a video on this. However instructions should be on the packaging and if you have any questions or need further help on this, please email or call us at: reloadersales@mecoutdoors.com or 1-800-797-4632
Just received a 600 Jr. Looks like from the 70's ? Any way to tell the age? Also looks like the original had it set up for 20ga. And way to set it up for 2 3/4 " shot and slugs? Thanks in advance for your time
Thank you for commenting. The resize ring on the 600 JR Mark V may be worn out and may need to be replaced. This is a part #8465 and can be ordered through MEC if needed.

Hi Nathaniel, Thanks for commenting. The single stage reloaders such as the Mark V and the Sizemaster models can be converted to different gauges with an additional die set.

do you have something that shows what collar to put in for 2 3/4 or 3 inch powder charge? I have a 12 gauge press, im looking to get a 20 gauge press. I'd like to load both 2 3/4 and 3 inch shells
Hi Thomas, The MEC powder bushing chart will show all the powders and the amount they will drop in grains. This chart is only an average received on a single stage reloader so it needs to be verified with a grain scale before using. The MEC powder bushing chart can be seen and printed off from the MEC Outdoors website (link below) The amount of powder to use will need to be obtained in the powder manual. If you have any further questions, please email us at: reloadersales@mecoutdoors.com www.mecoutdoors.com/Content/Images/uploaded/pdfs/PowderBushingChart.pdf

Hi J R, We do manufacture a charge bar for 1 ¾ oz. of lead shot #302134. This can be used on the 600 JR Mark V although the loads I saw in the powder manual were for a 3” shell. The Mark V will come with the parts needed to convert the press to 3” if needed. If you have any further questions, please email us at reloadersales@mecoutdoors.com or call 1-800-797-4632
Hi Anthony, The conversion for 3” are different depending on the model reloader you have as they are different for the 600 JR and the 600 JR Mark V models. The 600 JR will require the conversion kit #63 to convert to 3”. This kit comes with a longer support tube and instructions on the adjustments needed. The 600 JR Mark V model comes with the extra 3” spacer needed and does not need a longer support tube. The instructions for the Mark V 3” conversion will be in one of the back pages of the manual. If you have any further questions, please email us directly at reloadersales@mecoutdoors.com or call 1-800-797-4632 we are available Mon-Fri 8-4pm central time.

I have a 600 Jr. What's the difference between the 600 Jr and the 600 Jr MK V? Can my 600 Jr be converted to a MK V? What would be required? I just retired and I'm wanting to get back into shooting clay birds. Any Assistance would be greatly appreciated.
Hi Todd, The 600 jr was manufactured between 1968-1982. In 1982 it received modifications to the crimp dies and wad guide and was renamed the 600 JR 82. In 1985 this model was once again updated to the Mark V. The Mark V contained all zytel crimp dies and a U shaped eject bolt which now worked with high or low brass shells and could easily be converted to 3” shells if needed along with a couple extra parts in the parts bag. The 600 JR can be converted to the Mark V by replacing the old steel dies with the current zytel dies and then also changing over the deprime station to the current U shaped eject bolt. If you have any further questions, please call us at 1-800-797-4632 or email us directly at reloadersales@mecoutdoors.com. Thank you
