How to seat bullets with minimal axial error? I am loading 308 boat-tailed 150 grainers, and these ones have fairly short cylindrical portion of their length. There is always a question in my mind whether they seat perfectly straight or not. Apart from machining a custpm seating plug, what can be done to ensure the perfectly straight seating. Another question is how to evaluate the centricity of a loaded round. I am trying to roll the round and watch for wobbling, same as I do with crossbow bolts. But bullets are much shorter and do not show much wobble ever. Any ideas/suggestions are welcomed
 
Get one of these... Hornady Lock-N-Load Ammunition Concentricity Gauge or similar.

I also reload 150gr BTFMJ's as well as 155 BTHP, and 155 A-Max.

I too have wondered the same as you. I have considered purchasing a concentricity guage.

One thing I like about Hornady dies is the floating bullet seater that begins guiding the bullet and aligning it even before the asing has entered the die. Makes more sense to me than a fixed seater as found in other dies.

^^^ Exactly. You need a die that indexes off the ogive, not the point. Here is an excellent comparison done with various dies. http://riflemansjournal.########.ca/2009/09/reloading-seating-die-runout.html
