First post. Hi everyone and thank you for all of the info I have gotten from this website.
I recently purchased a Savage 12 LRP in .243 Win and am just starting to reload my own ammo. My first step was to determine distance to the lands in order to establish bullet seating depth. Well I didn't get very far before I ran into a problem. The ogive of the bullet is jamming into what I call the freebore area of the throat. In other words, the cylindrical part of the throat immediately forward of the chamfer leading from the neck area to the beginning of the chamfer of the rifling which I believe is call the leade area. It appears that this freebore area is the same diameter as the groove diameter approx .2425". The Hornady 105gn bullets I want to use are .243 in diameter and so won't go in far enough to contact the lands without considerable force. I reduced the diameter of one bullet to .242 and I am able to touch the lands easily. My question is this: is the freebore area supposed to be sized like this or should it be larger/tapered?
Just as a side note I have some 75gn V-Max bullets where my COAL measurement was actually 5 thou less than the factory round with the same bullet and sure enough, when I chambered a factory round and removed it without firing, it had visible ring around the bullet ogive.
