Unless that .270 is at least 2 pounds lighter than both of those other two rifles, it DOES NOT kick more, but it might feel like it does, as explained by Vapodog. Stock design makes a big difference. My buddy has a .300 Rem Ultra Mag and a .300 Weatherby, and both are a lot more pleasant to shoot than a .308 Norma I once had on an ' 03 Springfield action with a custom Paul Jaeger stock that had a Niedner steel buttplate! Ouch!!
