I have a stainless .338RCM Ruger Hawkeye short action and I want to lengthen the magazine up to around 3.1" for a useable OAL of 3.050". I want to switch from 225 grain to 250 and 300 grain projectiles. I know its been done before, does the bolt stop/ejector have to be modified? What else besides a longer box needs to be done? Thanks.
