MrUnderwood08 Posted July 15, 2021 Share Posted July 15, 2021 Looking to develop load for 627 using 158gr to 170gr coated bullets. Are you trimming down 38 special brass and if so to what length? I'm using TK moon clips for starline and will probably cut down brass I already have if it is okay to do. I seem to remember reading that some were experimenting with a length around .900 (between short and long colt). What dies are you using and accessories on Dillon (I'm running a 650). IE do 38 special case feed components work with the shorter brass? Thanks for any help. Link to comment Share on other sites More sharing options...
Fishbreath Posted July 15, 2021 Share Posted July 15, 2021 It's my understanding that you can't trim .38 Special to Short Colt because the web starts too high in the case, and you can't seat bullets. 'Mid Colt' works, though. I actually just ordered a 750 plus casefeeder, so I'm up to the minute on the right accessories. According to Dillon, you need: * The small pistol casefeed plate * F (9mm/.38 Super) powder funnel * .40 S&W purple casefeed adapter * Remaining parts from the .38/.357 caliber conversion kit I plan on using Lee dies for size/seat/crimp.

MWP Posted July 15, 2021 Share Posted July 15, 2021 There’s no advantage to .900 over going all the way to short colt, other than there’s more case to send in and out of the gun. Get short colt brass, put a 38special die in the sizing station, a 9mm die everywhere else and send it. Link to comment Share on other sites More sharing options...

The 9mm factory crimp die works fine for me, with the adjustment dialed almost all the way out. Puts a nice straight-wall crimp on. The carbide final-sizing ring isn't a concern like some people say (or hasn't been for me), because the sizing ring has to accommodate the largest width of a 9mm case, which is .390". Plenty of room for a .379" .38 case to fit in without getting squeezed. Link to comment Share on other sites More sharing options...

The only other thing I change is the Case Feeder Plunger, I use the Medium rather than the Small (which I do use for 9mm). Makes the S1050 run a lot smoother with less times of the cases hanging up on initial feeding into the press. Also with 38 Short Colt brass keep the oal of the load above 1.170" with those heavy bullets. I use .358 160 crn from Bayou, BBI and if loaded shorter they will occasionally create a bulge midway down the case that won't chamber. Due to the web.

'Mid Colt' works, though. I tried trimming 38 special to 38 super length. I averaged one keyhole on the target per cylinder. I believe I was into the web of the case at a length of .900.

On the 1050 with a case feeder it's the part that retrieves the case from the tube and seats it in the Shell Plate. https://dilloncdn.com/manuals/dillon-super1050-manual-english-page-31.pdf Link to comment Share on other sites More sharing options...
