[QUOTE="boomtube, post: 332648, member: 9215"] Woods, those are some good photos! And I lust for Brown and Sharpe calipers! :D I find the Hornady "modified cases" to be a problem in that they are seated to the shoulder, not the face of the bolt. Shouldn't be a LOT of difference but it's sure not the same as against the bolt. Marking my dowel squarely and consistly is assured by making the muzzle itself a guide for my knife or razor blade. Then, the only ambiguity is my ability to place the points of my dial calipers exactly on those marks! I also have your R-P type sliding collars for my rods or dowels but find the knife marks are just as easy, for me anyway. But, I've come to realise that there is no real need to be all that precise anyway, not unless I'm actually trying to seat AT the point of contact. I don't do that, so all I really need is to be close and then use that OAL reference to set back in .005" steps until I find the actual best shooting OAL. And even that isn't a specific spot, plus or minus nothing. Best OAL is a range, typically as wide as 10-15 thou for me. I strive to seat in the middle of what ever null exists and then slight variations in OAL, either real or to some measurement on the ogive doesn't matter, at least not in my rifles! [/QUOTE]
