I am planning a build with my model 11 in 300wsm I want to change it to a 6.5x284 for my girl friend. right now it is a CRF how hard will it be to change to a push feed and what parts will I need to swap out, besides the bolt head? is it even possible to swap it out? I already have the barrel ordered and need to figure it out soon before the barrel is already finished. Thanks Jay ???
