I am not near the expert that others on here are, but I would think that you would be well served to return the 2 chokes you bought, and purchase the jelly head. Saves you $10 and you have a better choke, in my opinion, than the 2 you bought would be.
Also, Remington does not recommend a "heavier than lead" shot through this choke...so neither would I. You COULD shoot it, but would no doubt get less than optimal results. Now, through the jelly head you could shoot it...which brings me back to what I said initially. This is just from my experience. Listen to what some of these other folks say though...they have much more experience than do I.
