RE: Remington 7mm Ultra Mag
I have a 7mmultramag and two 7mmstw's.The extra case capacity of the 7mmultramag only adds 50fps to 75fps velocity over the 7mmstw despite burning significantly more powder.People are realizing that the large ultramag case doesn't add much using 7mm bullets so sales are slow.On the other hand the 300ultramag is doing much better sales wise.
