Are you able to post a photo of your 47 x 376R Cartridge?

Find a brass bell that will fit over top of your case, a longer bodied bell will have a better shape than a short angular one. By placing the bell on top of the case and striking it with a mallet you will force the bell down over the case and this will resize the top of it,, which seems to be the problem, I use one all the time on 37mm cases, you do this until the fit is what you want, this will work on the top 1/4 of the case, You can't go much farther than this or you will curl in the top too much The longer and less severe the shape of the bell the farther you can go). But this method helps and from what I see may be all you need. Annealing as described is a good idea first. The bell has to be smooth on the inside or it will leave marks.

Perhaps easiler to find a 37mm projectile (any 37mm proj) and just invert into the case mouth after heating to cherry red tapping around the case circumference - yes may take a "few" goes until perfection!

(of course don't go using a nicely painted one!!!)

to do it correctly, you fill the case 1/2 way with water or place in jar with water to 1/2 case length, you will need to heat the top 1.5 inch of the case with a touch to red hot. let cool if no cracks at the mouth, if cracks, you must repair these while heat treading, , clean with liquid brass cleaner, apply hight temp flux, place hose clamp around lip, lighten until crack close, use a low temp brazing rod, heat red hot and apply rod just enough to fill crack, this will also heat treat the mouth of the case. , now you will need to machine or have a shop do it. you will need a round stock of steel about three inch OD and at 5/8 inch thick. you will machine a taper hole in the center of the round stock. only first 1/8 inch has the taper . hole ID is your final OD you wish on the brass case, plan on 0.005 over the size of the projectile, plus the total case brass thickness, now you have the case ready to resize. best to use a lathe, as i sometimes place a projectile of the proper size nose first in case. open chuck so not to touch projectile, carefully place case into the steel ring, slide projectile hose first into case. , move lathe post base slowly forward to push on the base of the case -keeping all align . now you must move the lathe base forward to push the case into the die you made. carefully remove the assembly, remove lose projectile from case. now you will have to drive the case from the die you made. i use a piece of pipe, place ring on top of open vise, pipe into case, insure case will fall free,, drive out the case and catch it before fall to the floor. use grease on die and projectile so you can get it apart. joe gatz CWO4 RT
