I too voted prior to brass being an option.   The RMC are stout and I bought 10 eons ago (less than $4 a piece).   They take the 209s well.

I have an oddish loading.
Drive spent primer out with dowel, fitted with blunt nail.   It is a 5/8 dowel and taps the spent primer out easily.    Next, thumb seat 209 primer (after cleaning of course) and use a 2nd dowel that is dished to seat with just another tap.   Pour in 80 grains of ffg, through a 24 inch drop tube.   Place card stock over and seat with dowel.   Add fiber wad, seat with dowel.  Using the 80 grain measure (I made it from a plastic tube), measure and pour in #7 lead shot.   top with a card stock and seat.   Then run a bead of elmers white glue around the edge to seal. 

I do the same with plastic hulls that have had the crimp portion cut off.   

I will say, I have never patterned them.   We do not shoot a lot of shotgun in NCOWS, but we do a texas star with shotgun, rifle and pistol.   with the brass shells, it is the one of the 3 I will take all five targets out with.   

Less than two weeks to go. The weather looks pretty good, forecast is for mid 60's to low 70's with low rain chances. A reminder that we'll be providing a grill for Sat. night, bring what you like. Looking forward to seeing everyone.

The third gun sits in your guncart as a spare for the one you're shooting...

If you really really really like something you better get 3.
Because 3 is 2
And 2 is 1

And if you really really really really like something, i guarentee they will stop making it.

Forget who said that…..

Since I already voted, it won't let me vote again for brass shells.  But I also don't use them very often these days, partially because they slow me down on loading into the SxS (no crimp), and they don't always eject as well.  I know some of that is the old Rem-UMC hulls needing to be annealed, because even though they go in round, the mouth is a bit out of round after firing.  However, Mako (with one dorsal) I have not had any problems with lack of oomph out of my brass loads.

But I do still like shooting the all brass at times.  My reloading has been split between two locations with limited time for a while now, but that is changing as I get things consolidated and moved over the next year, so hopefully will get some more brass loading done.  I've also got a lot of Alcan brass hulls, which are thicker than the REM-UMC / Winchester / Magtech but not as thick as RMC.  They use a Remington 57-style primer (I think that's it) that looks like a 209 but is smaller.  Fortunately I have a couple thousand of those.  One problem I have with those is that a lot of them 2.5" but some are different lengths up to about 2.75".  When firing them, I have to pay attention that I'm shooting the longest ones first, followed by shorter, or they will stick in the chamber from prior fouling.  They need to be all trimmed to 2.5" but I have no way to do that.

Mako, yes the RMC hulls are the machined ones with the same internal dimensions as a plastic hull and use 209's. They're still around, last I looked those were about $8 each.  I have a half dozen of them but don't use them much any more because the primer pockets are so tight that priming and depriming are both very difficult.

Yep.  Found what I needed.
