From personal experience, and each hand loader using RCBS equipment in his own time will also find this out, RCBS stands behind their equipment 100%. If you break it in the normal course of hand loading, they will fix it and won't ask you why. If you jimmy it up, twist it off, shear it, drop it, bend it, cross thread it, or just plain booger it up, they will fix it or give you a new one. I suspect they are experts at renewing used equipment.
De-priming pins are a primary target that get bent. They will send you a couple of spares and neither charge you for the spares nor for the shipping.
I purchased RCBS .270 caliber Winchester reloading dies through Midway USA. My 0.277" bullets would not fit snugly within the reformed case necks. Turned out that the resizing die contained a 0.281" neck sizing reamer. I called RCBS. They shipped two (2) 0.277" reamers to replace the too large one. No charge. Stuff happens.
On another instance a 270 case head separated from the case holder due insufficient lubrication on the Rock Chucker ram's upstroke. All of the now destroyed case was hopelessly stuck within the die. An attempt was made to return the ram to the predamaged case position which only exacerbated the damage...now to the resizing reamer itself. The resizing reamer would no longer extract through the top of the die. It was bent in three places inside the die. I was stuck and stuck BAD.
Eventually I worked out the stuck case and bent reamer, called RCBS, and within days they had shipped me a new reamer no questions asked. I offered to pay. They said "No way." Can't argue with that.
RCBS is quality and customer service at its best. For that they deserve and engage our continued purchase of their products.
