Yeah that would be me! I would only load special rounds. I’ve stocked up on number 1 buck and slugs already but experimental rounds would be me all the way. My JM pro eats cheap bird shot all day. I got a good one. Shot 100 cleaned gun and I did that 3 times. Since it never jammed I shot 100 3X in 3 months and never cleaned it. Still no jam but it was a ***** to clean. Love my JM PRO 10 shot tube also. Now I clean after every session to make it easier. Thanks for the advice I may just buy the sm82Western Field 550.... Nice! MEC SizeMaster82 or any of the MEC shotshell reloaders are good.
Is it worth it? It depends on the person, what you're reloading, and why you're reloading. For me it's more about the mental exercise and joy of doing it. Second to that is being able to reload ammo that has disappeared from store shelves or is hard to find. It gives me many more options. For experimental loads I often use a Lee Load-All II or a roll crimp tool and drill press. It saves having to readjust my MEC for experimental loads. 😉
For most, 1 1/8 oz and 1 oz trap and skeet loads are not worth it anymore. Many of those guys are just buying the 100 round value pack at Walmart. Some are more picky or want a light recoiling load to meet their power factor, so they reload 3/4 or oz 7/8 oz 12 gauge loads.
Field loads, not much saving here.
Buckshot & Slugs, oh yes if you are shooting a lot! This is where the biggest saving is. Many are casting their own.
Novelty and specialty loads, yes if you enjoy shooting them or cannot find them on local shelves. If you are just interested in shooting a few, War Wolf Ordnance loads good stuff. For Specialty hunting loads that don't use lead, it can be hard to find exactly what you want on shelves in Mississippi. Reloading, Roto Metals, Ballistic Products (BPI), and Precision Reloading can provide a solution for making your own.
