Description: 357 Herrett


The empty case on the right is where the 180 XTP should extend down to having an OAL of 2.040. The red line underneath is where the 28gr max charge of 1680 should rest.


The case on the right:


I set the seating die to set the 180 XTP’s .010 off the chamber. The OAL is 2.41. The black line on the right of the case is where the base of the bullet is. The black line on the left of the case is where 35gr of 1680 rests at...


I have set a 200 FTX and a 180 XTP in dummy rounds and they only seat in the brass by .1 of an inch. They will hold, but they are REALLY far out. This is also going to mess with my all of my reloading charts...


The XTP bullet has an OAL of 2.41
The FTX bullet has an OAL of 2.725


Worst case scenario, this becomes a 35 Rem Rimmed and I buy a new 357 Herrett from MGM. LOL
