Re: Whidden bullet pointing system???
Some observations...
A while back, I got the meplat trimming head for my Giraud trimmer. Life was simple (insert bullet or loaded round into the 'pencil sharpener' until trimming stops, remove, repeat with new round, etc.) Made groups a little 'rounder', no real noticeable difference in come-ups.
Somewhere along the line I happened to measure some 6mm S107MKs before trimming, noting the wildly varying OAL. Then measured them again after trimming. Still varied quite a bit. Not as much, but still more than I liked. Since this unit (Giraud) indexes off the ogive, I presume that the variation is showing up there as well... which is a bit disturbing.
Later I got the Whidden pointing system with the meplat uniformer. I really debated over the latter part, as I already had one (the Giraud) and most if not all the other ones I've seen index off the ogive like the Giraud, Tubb, Sinclair, Hoover, etc. The Whidden meplat trimmer is the only one that trims based on OAL, which seemed a little odd.
I must have misread the directions or something, because I started out meplat trimming then pointing. Got damn near perfect consistency though. Along the way someone pointed out that the directions recommended that trimming along with pointing wasn't really necessary. So... went back and tried just pointing. I got absolutely horrid results with the first few. Looking at the tips, I realized that this particular box of B105VLDs had big snaggle-toothed meplats (kind of like SMKs, only worse) and the variations were causing the pointing process to be inconsistent. I tried trimming them after the fact, but the tips were so bad that some would catch on the cutter blade and start to 'unfold' - not cool. So, I went back to trimming first, then pointing, and life was good.
Later I started in on a different batch of B105VLDs, and these had the nice small fairly uniform meplats that I normally expect from Berger. With these I could 'get away' with just pointing and not trimming.
From what I've seen so far, trimming before pointing helps make the pointing more consistent - if necessary. Trimming after pointing does also... but the amount removed is so miniscule as to be negligible.
YMMV,
