Sometime in the last year or two, I read an article or post about how to size/prepare a case to accept a bullet with a near-slip-fit. The idea is then to put that case, with a bullet of the type you are developing a load for, but no powder or primer, into the gun for which you are loading. You leave the OAL quite long. Then, when you close the bolt, the ogive of the bullet will bump the rifling and begin sliding back into the case Carefully extract the case and bullet, and measure... that should be the OA length that gets you just on the lands. Set up your dies and adjust from there as desired/prudent. Well, now I can't find that article/post. Does anyone here use this method? If so, how do you prepare the case for this use? How do you avoid putting back much neck tension... after all, we're not trying to jam the bullet any distance into the lands... just touch them. Any help? Thanks in advance.
