new acme coated 125 grn fp 38 special no crimp groove better or not

[tk71]

I use acme 125 grn fp with crimp groove but i noticed now they use a 125 grn fp with no crimp groove. Has anyone used these or this type of bullet and what crimp do they use.

I use a taper crimp in all revolver cartridges.

I assume you're using for 38/357. Likely Acme wanted one bullet for 38/9mm to speed production, 9mm uses a taper crimp. Suggest using either a Lee or Redding taper crimp die after seating the bullet. Note do not over crimp.

what Gun are you loading for and what power?

 

All of my 38 spl have a moderate crimp into the crimp grove because they also get shot in lever action rifles (CAS).  This is to prevent bullet setback from the magazine spring. 
 

For a straight sided bullet, I would probably try a moderate taper crimp (38 Super FCD comes to mind).

I shoot a  357 single action revolver 125 grn fp acme coated lead  light crimp in the groove 4 grns titegroup. These bullets shoot really good. I use a lee die set using a fcd roll crimp for the last step. The new bullet is flat point no groove.
