   Fisherman liked post by Puffin On thread : Bullet seating centricity any tricks and tips?

   New Lapua brass can be quite undersized in the neck generating heavy neck tension. Some seating dies may deal with this better than others. Things could straighten up on once-fired brass when you get...

   Thanks Guys, some useful information. This is a great topic and now that we have grown tired of discussing ladders, OBT, OCW, and 3-shot groups, doesn't this deserve its own thread at some...

   I've offered to help out at one of the stations and do some spotting for you guys as required. To be clear that means in this case confirming where shots have hit. It will be good to put some names...

   If going with a short action then - as has been pointed out - the 6.5x47 gives the most flexibility for bullet seating. To provide some figures I load 140gr VLDs out to 71mm (70.6mm is just touching...

   Agree. I'm assuming that time is fixed, but no figure has been given, and then the crossing of the data plots in figure 10-33 is unintuitive. Also online searches reveal a differing in opinion over...

   For steels, not for brass according to the literature. Not completely unfortunately. The head around the perimeter for the few millimetres where it emerges from the chamber - from the upper...
