600 JR MARK V 12ga
The MEC 600Jr Mark V is a fantastic shotshell press. Aside from an accurate scale for confirming powder and shot charges (and the obligatory reloading data and components, of course), it encompasses everything you need to start loading/reloading shotshells. The press is made of good quality materials and comes pretty well adjusted right out of the box (although I did need to adjust pre-crimp and final crimp for the particular shells I was loading, but that's to be expected). Press operation is smooth and easy. Setup instructions are clearly written and easy to follow. I would definitely recommend this press to someone just getting into shotshell reloading, but I think it's also well suited for seasoned reloaders who are adding shotshells to accompany their metallic reloading repertoire.

600 JR MARK V 12ga
I started out handloading individual shotshells -- buying primed hulls, measuring shot and powder charges for each individual shell, roll crimping on a drill press, etc. With the addition of the 600JR, I've been able to drastically increase my efficiency, produce a more consistent and reliable product, plus have a lot more fun in the process. I've been recommended this product by beginners and experts alike, and for the price, I'll have to agree.

600 JR MARK V 12ga
A well made product that works as it should. The addition of the primer feed further speeds up the process. Straight forward quick processing of shells for a single stage unit as long as you choose the proper powder bushings. Very satisfying results using this model. The unit is simple enough for a beginner and useful for the experienced. Due to its size and dimension footprint you can fasten in to a board and make it portable reducing the permanent space used on the workbench. I should have purchased one of these years ago.

600 JR MARK V 28ga
Quick delivery. Well packaged. I knew I would have to reload for my new shotgun as 28 gauge is hard to find and crazy expensive when it is available. Like my experience with other MEC products, the quality is great and the unit functions perfectly. I only needed to make a couple small adjustments to the crimping station to start producing factory quality shotshells. I did add the auto primer feed as it really speeds up the loading process. I have loaded around 500 rounds so far and everything has run flawlessly. Can't go wrong with MEC loaders!
