I have a 6.5x55 Swede on a long action MRC 1999. Custom order before MRC would build a Swede on short action. I did a test with 8 different bullets. Could get every bullet but two to kiss the lands at COAL less than the MRC 1999 Short Action magazine length of 3.125"
The two exceptions were a very pointy Berger VLD bullet (no surprise). And the Hornady 160gr RN. Seems that the Hornady 6.5mm 160gr RN bullet actually has a certain amount of taper, apparently to reduce bearing surface. It does not become "full bore diameter" until at least half way back to the base. OTOH, the Norma 154gr RN fills out to full bore diameter very quickly and would not have any trouble touching lands in the MRC SA 3.125" magazine box. Long story short, not all RN's are created equal...
