Would like to get a Dillon Square Deal B to load .38/.357 only.
I prefer to taper crimp everything I can.
Dillon does not and will not make a taper crimp die in that caliber for the SDB.
Have considered buying a Dillon SDB roll crimp die and trying to get a reloading die maker to ream the roll part of the crimp out to a taper crimp.

Is this practical, and does anyone know any one that would do it?

taper crimp

I have several square deal machines, one in 38/357. in my opinion you need a roll crimp for a revolver round to prevent bullet pull on heavy loads.
I have been using my for over 20 years without any problems.
 
If you are shooting target loads you do not need to crimp,
just squeeze the wall back straight so the cartridge chambers nicely.
You could also probably get away with using a 9mm taper crimp die
You could also taper crimp on a single stage press after the round is assembled on the SDB

Why? Sorry to be nosey, but I really would like to know why you want to taper crimp .38/.357. Especially .357....

Dave Davison over at CH4D can hook you up with a taper crimp die,
you might consider getting a complete set of dies with both a taper and roll crimp die, just in case. CH4D makes excellent dies.
Something I've wondered about, will regular dies work on Dillon presses or do you have to use Dillon Dies with them ?

Square deal press uses proprietary dies. Other Dillon's use regular dies. I wonder how a very light roll crimp differs from a taper crimp as a practical matter. I have been loading double end wadcutter 38 target loads for so long, I've not had to worry about crimp.

I already have a Dillon 550 and that's what I have been doing.
May try the 9mm taper crimp die idea though.

A taper crimp die spreads the area of the crimp over a wider area down from the case mouth, which increases friction and makes moderate variations in case length less of a problem.
Case length variation makes a bigger difference with a roll crimp because a slightly longer case causes the die to really turn in the case mouth more than may be desired.
I don't load full powered .357 loads.
If I'm going to have all that extra blast and recoil,, I might as well be shooting a .44.

All Dillon presses except the Square Deal B take standard dies.
The SDB requires proprietary dies that are made with a much smaller outside diameter so they can be located in a tighter cluster on the top of the press. Don't know if the threads are any different.

With a taper crimp, case length does not cause the variations in crimp tension that a roll crimp does.
Also, I only shoot lead bullet loads that are generally not much hotter than +p at the upper end.

Don't like the extra blast and concussion of full .357.
If I feel the need for more power I shoot my .44. For all the extra noise, might as well have a bigger hole.

Have moderate tinitis already. Even with plugs and muffs, full .357, .30-06, belted magnums, etc. make the ringing in my ears worse at least temporarily, sometimes permanently.
For that reason, I only shoot black powder, moderate powered center fire pistol, .22 rimfire, and center fire pistol in lever action rifles any more. If I am somewhere where someone is shooting really loud guns or loads I get back some distance.
I am probably only about 5 unprotected shots away from needing at least one hearing aid.

Smoothshooter, you might want to consider wearing ear plugs under muffs, if you don't already. Not only does it provide more decibel reduction, it also reduces the possibility of an unprotected shot.
 
smoothshooter,

why not just seat the bullet deeper, where the shortest case when gently roll crimped (belled case just straightened out) doesn't engage the bullet. You will get better neck tension (more bullet in the case) and better combustion with your moderate loads. If using full power loads, WHICH YOU ARE NOT, then you will need to reduce powder charge if using this method.

Scratch that idea , but if Dillon makes a 38 super auto taper crimp die it should work best. But buying a set of Dillion SDB 9 mm luger dies and using the taper crimp would be more practical , if you ever wanted to load 9 mm you are set.

My press is blue but it's marked Bair.
