Hoping to gain some knowledge for my next build. I am building a 338 lapua improved and will be shooting 300gr berger hybrids. I am trying to find out what action and bottom metal with magazine will work for this round. Does defiance make an action suitable for the 338 lapua improved. Also will the seekins bottom metal and magazine work with the defiance action. What have other guys used for this cartridge. I would prefer to use an hs precision bottom metal with magazine for my build but what actions would be suitable for this? Basically I would just like to hear from some other guys on what they have used for their builds. I am set on the 338 ackley version of the lapua so please don't tell me the reason not to build it im just looking for some advice on this build.
