260Remguy, nsaqam, I have no doubts about more velocity equals more pressure. The link was wrote by Bob Jourdan in 2003 and is one of many articles wrote about the 6.5X55 Improved case, others are PS magazine May 2002 which compairs the 6.5X55 Vais to the 6.5-284 claiming them to be "ballistic twins" and again in PS magazine Aug. '92 another Bob Jourdan write up compairing the two cartridges. Dr E.L. Arch also did extensive testing of the cartridge with excellent results, yes.. twist rates, powder, barrel length and bullets used will all effect the results as we all know however the 6.5X55 B.J.A.I. is no underdog by anymeans. The benifits are proven with a Improved cartridge and loads don't need to be at the max to obtain supurb accuracy. I built my 6.5 on a Swede M96 military action that was sportorized and have had no issues with pressure signs. Accuracy was excellent even during fire forming with 85grn bullets.
