I came across a pretty good stash of 16 Ga. 2 1/2" RST Hulls but have been frustrated trying to get a good reload on these. Have tried both roll crimps and star crimps; they are kind of light so they tend to collapse. I fill them with popped popcorn to get the right volume, then an over-shot card. To get a good seal, I use parafin. I have not chrono'd them yet. My production rate is low and it may well be that they take more time than it is worth. any thoughts? thanks, Gil

They’re Cheddite hulls….should load up just fine using a SG16 type wad. I don’t put hardly any wad pressure when seating the wad….as soon as the wad passes the wad guide fingers on the press….I drop the shot. Should crimp just fine after that. I load 3/4 Oz shells for target 16 gauge loads.
I find that you’ll probably get 5 to 7 reloads out of each hull before you gotta trash em.

DR16 wads are next to impossible to find.

I don't know how much experience you have roll crimping or what type of crimper you have.

Once fired shells rarely roll crimp well unless you can cut away the star crip or iron out the roll crimp to look new.

I use a BPI crimper and warm it up on some throw away hulls and lube it with just a smidgen/dab (yes that is a unit of measure) of anti-seize lube . Start the crimp slowly and you can feel when the crimp starts to roll then move the crimper down a little quicker.

I like to have block of loaded rounds ready so the crimper doesn't cool between rounds.

Star crimping be sure you have the correct crimp starter in (6 or 8 point) and your machine adjusted correctly. I use a regular MEC 600 16ga with a short shell kit in it. Star crimping once fired roll crimped shells rarely works well unless you ironed out the roll crimp to look new.

After the first shot the rest are just noise.

Another question, this regarding the loader--a MEC 8567 Grabber. I tried getting the 3 crimping stations adjusted to handle the 2 1/2" RST's. I must have spent 2 hours fiddling with them (probably the first time I have needed to do that on any of the MEC loaders I use for the other gauges). I can say I didn't do very well. I think I have it back to where it was before but not even too sure about that.

I have done roll crimps by taking them out of the assembly line before they get to the crimping stations but am trying to avoid that. (Rolling them by hand and that worked fine.) So I am wondering if there is a better way to adjust the loader(using the crimping stations) to handle the shorter hulls and not doing the roll crimps. Thanks for the input! Gil

I've loaded hundreds of the 2 1/2 16 g RST Hulls. I use a Mec 600 jr setup for 10 g to de-prime and prime and load shot and powder using a Lee Load All for the shot and powder and finish by roll crimping use a drill press.

I think part of the problem may be your use of popped popcorn to get the right volume and when you go to roll crimp the popcorn deforms/compresses in an unpredictable manner.

I'd suggest a different wad and/or adding fiber wads and cards to get the right height. Otherwise try a different filler that is more predictable, such as grits, cream of wheat, etc

It sounds as though you're trying to remedy the crimp issue
from the top down instead of the bottom up.
Are you using the "Short Kit" ?
No fiddling necessary.

BPI has a vise too for about the same price if you decide to drill or drill press them too

Definitely get the BPI Vise if you use a drill press
