Dan, well, STW will be about maybe 200fps faster than a remmag, and RUM about 100fps faster.
I get 3100fps with 160gr accubond out of my STW. I am not pushing it near like wildcatters used to do.
I have ownedthree 7mmremmags,three 7mmstws and a 7mmultramag and have firedseveral other 7mmremmags,another 7mmstw and another 7mmultramag.My own chronograph reading have shown the 7mmstw to top the 7mmremmag by about 250fps with the 7mmultramag being another 50fps to75fps faster than the 7mmstw.
