Didn't see this mentioned but could have missed it. The original 6.5x55 FMJ was an extremely long bullet with straight sides and a round nose. Nothing anywhere near its case size has a bullet that sticks out nearly as far. The 6.5 Sil looks like it was made to be shot in Swede chambers. Not sure you could ever seat that boolit deep enough to not hit the lands in a .260 of any flavor. This is a soft point but has the same shape.
