chrispti Posted July 17, 2010 Report Share Posted July 17, 2010 Crispti That is the conclusion I keep coming back to. Do you know if the xtrema 2 is lighter than the xtrema 1? have a good weekend all I dont mate. Im sure you would be able to find something on the internet somewhere :blink: The 400's kick off (KO) is very soft and will ''activate'' (if you like), with a moderate pigeon cartridge, as it is designed to do as its an upland/game gun. A heavy goose load will just ''bottom it out''. The Xtrema2 KO is much stiffer and only really activates with heavier loads making it ideal for wildfowling / goose loads Hope that makes some sence Quote Link to comment Share on other sites More sharing options...
retromlc Posted July 18, 2010 Report Share Posted July 18, 2010 I think the A400 kick-off is probably "softer"at the butt pad as it has an additional third dampner which is struck by the bolt after the shell is fired,pre-obsorbing some of the energy,the A400 has a different type of gas vent system,which lets more gas escape with the heavier shell,i've seen one stripped down,I think this all adds upto a completly different way of dealing with spent gas and energy from heavier loads over previous models,From those I've spoken to who have kick-off's on their guns they all bottom out Quote Link to comment Share on other sites More sharing options...
