I have loading dies of several makes, mostly RCBS. The last two die sets I have bought have been three-die Redding sets for rifle cartridges. I look forward to using the Reddings because they are easily the best looking dies I have ever seen, and seem to operate a little smoother than others. (That may be a subjective impression.) Recently, I was gifted a sample of Saeco 352 boolits for trying in my .35 Whelen. This boolit has a flat point and the seating punch in the Redding die, which has always worked well for spitzer and roundnose bullets/boolits, could not seat the 352s to a consistent depth. I looked at the punch and realized it was a big, fat,1/2"-13 thread. That is SAE, available at any hardware or auto parts store. My "machine shop" consists of a 3/8" drill and a good Baldor grinder. I got lucky and ground and filed the threaded end of a bolt down to .400 (reasonably centered) so it would enter the die, and hacksawed it to length. This made a flat point seating punch, good enough to seat the trial boolits consistently. If I decide to add a Saeco 352 to my mould collection, there will be time to order a proper punch from Redding, but the Tru Valu bolt got the job done. Lyman also uses 7/8"-14 threads for seating punches.
