Has anyone ever loaded 38 148gr DEWC bullets in 9mm cases?
I'm going to attempt it later for a benchrest load.

I have not tried it but I will bet there will be problems feeding it and watch the propellant levels if you have to push it into the brass more than a standard heavy weight RN bullet of the same weight. PS those are usually 147-148 brass grains. Also the brass will taper thicker fast once below the usual bullet insertion depth. I would make a couple test rounds without primer or propellant and see if you get good case neck tension and do not bulge the brass. Then see if they will feed reliably. Oh yeah have fun experimenting.
2 potential problems I see.(although I feel like there's a hidden fact to this question, like it's for a revolver or something)
The bullet will stick out so far it will hit the rifling and prevent chambering or it will have to be so deeply seated that pressures will be hard to control or estimate.
It would make for a very efficient revolver round.

Make that 3, the .357" or .358" diameter bullet could cause the overall cartridge diameter to be too big,preventing chambering, or some combination of all 3.
C'mon now, what's the catch?
Blackhawk with 9mm cylinder?
T/C single shot carbine with custom 9mm barrel? (don't laugh, my buddy has one)

Oh heavens, NO!
Apart from the three very real problems that PO2Hammer already identified - any of which should have you running away from this idea as fast as you can -seating such an oversize bullet in the 9mm case (assuming the distended case would then chamber) would reduce case volume enough to push the resulting cartridge into dangerous pressure territory. See Speer Manual, 11th Edition in which a reduction in case volume by seating bullets 0.03 inch lower than specified DOUBLED the pressure of the round.

If just trying to use up some .358 lead 148s, I'll buy them from you and then you can buy some .355 fmj 9mm bullets.
Just a thought.

You are assuming he will seat them deeper than specified for a 147 grain bullet. He still hasn't told us what firearm.

If it's in a 9mm revolver I can certainly see merit. In semiauto I would not expect great function. Wide flat bullets don't feed well in my guns and I would not expect them to do well in any semiauto without stove piping regularly. As for the diameter, I wouldn't be super concerned provided it still chambered. Lead that soft will swage down when seated in thick brass. If it won't chamber it just adds the step of running loaded rounds through the sizing die with the de-capper rod removed.

I loaded up 25 to an OAL of 1.10" with 3.3gr of Green Dot behind them. They functioned fine by hand so I took them to the range. Half of them wouldn't chamber after firing the previous round, wouldn't quite go all the way into battery, half of them fired and functioned, no problem. No stovepiping, the only problem I encountered was not quite going fully into chamber. Grouping was very very good at 25yds.
I'll think I'll scrap the idea however. I hate to seat them any deeper though I do think this will solve the chambering problem.
