[QUOTE="Long Time Long Ranger, post: 281962, member: 505"] J E has an exceptional point. I have built rifles for 35 years on all kinds of actions and currently own excellent shooters on virtually every action out there. Like J E said they all can be made to shoot very well if the guy knows how to work on that particular set up. The remington action is the most mass produced action in the world with the most aftermarket parts and the primary action most gunsmith schools teach on. So remington gets the most talk because that is what most smiths are familiar with. I have heard them badmouth the crap out of wby's for 35 years because they don't know how to work with the wby's and want to hold onto there customers. For 60 years the gun world has been chasing weatherby's and trying to compare to a weatherby. There are a lot of smart guys out there who figure if everybody's been comparing everything to wby for 60 years then I will just get a weatherby. Now for your question. The weatherby mk 5 action is the best commercially produced action available for the big 338's. It is the only one designed for such cartridges with a great trigger while the others tried to make there action fit the big cases and are just not a good fit.
