As I said, if you have the recipe and the components, almost anything is reloadable....once.
What you really want in a reloadable hull choice is something that can be loaded again and again.
Remington ribbed hulls are not known for their durability or friendliness in this department.
My shotgun, a mossberg 500, absolutely loves the cheapy Remington 1 oz slugs. I can buy them cheaper new than I can reload them...so when I can find them priced just right, I stock up. I've fired about 24 or 25 different types of slugs to come to that conclusion though.... I was just lucky it really likes what is frequently the cheapest of the lot better than everything else. I was not satisfied in picking "x" brand slug because it came recommended well, or had "y" price point... I did a lot of testing. I recently found a great deal on "q" brand slugs, but still bought 2 boxes at wally world to test them out.... they worked reasonably well, so I bought the lot of "q" shells because the price was too good to pass up.
Their premium shells such as anything in the Nitro and STS lines are a great choice. They Generally (Nitro) come with birdshot, but can be reloaded with Shot, Slugs, or Buckshot very easily and repeatedly....which is the key.
Generally speaking quality hulls are difficult to come by in Buckshot and Slugs. Manufacturers do what they can to keep the cost per shot down. Lead, Powder, Primer, and Wads are pretty much standard for costs.....where does that leave room for cutting cost ? You got it, the Hull.
I would seriously consider buying a few boxes of various types of shot, slugs, etc and testing to see what works best in your gun. Not all Buckshot, slugs, and especially Birdshot shells are created equal. Mix in choke types, and you have a lot of experimenting to do.
You would be very angry to purchase a case of "X" brand Buckshot at say, 75 cents per round, only to find out it functions horribly in your shotgun, wouldn't you ? The pattern could be bad, they might not feed correctly...... you might luck out, but odds are more in favor of you crapping out.
Granted, any shell is better than no shell....... But I would never consider buying a substantial amount of anything based solely on conjecture, good faith, and hope. Test, test, test.....then buy in bulk.
