Good luck with your quest to load shot shells.
Mec is a good choice, and I am sure there are other brands that will work.
I had some Pacific presses that i sold a few months ago, and it surprised me what the brought.
I actually like the way the Pacific loaded better than the Mec. However it seems awkward, as it was arranged backward.
The 410 is a pain in the rear to load for. Its just so small, and the shot wants to hang up in the drop tube and the fall out on the floor when the handle bumps the top.
With the 410, Its easier to keep the shot bottle empty, and dip the shot into the case, with an adjustable dipper, or home made dipper, made to the correct size, after seating the wad.
Nope. My 2 410 loaders will bridge in the drop tube occasionally. tapping on the side of the press frees the shot up. Once you learn the eccentrics of loading the 410. You can load them almost as fast as a 12 or 20 ga..
Looking at my loading log. Since 2019(when I started loading 410). I've loaded 5633 rounds or 225 boxes. It's not a pain to load for if your machine is setup correctly.
