[QUOTE="trickytune, post: 968733, member: 69289"] Hi I have been reading as much as I can and just done some testing now I need answers! Quick run down first Rifle Savage 16FCSS Weather Warrior 260 Remington Projectiles Berger 140 VLD hunting and Berger 140 Hybrid's The rifle is brand new unfired as I am waiting on my Forster Ultra seater dies to be made. So while I wait Im trying to do as much as I can and my aim is to develop a load with as few shots fired as possible or at least be pretty good. As I can't go down the seating bullets in a cartridge road yet I have used a cleaning rod (very carefully) to mark bolt face to end of barrel then I measure from end of bullet tip to end of barrel and using a short piece of arrow shaft to lightly hold the projectile in place i take a measurement. These measurements I can take almost 100% repeatable. With the VLD I get 2.893" COAL and hybrid I get 2.948" COAL. Then with a marker pen I make the projectile black and get a mark from the lands gently as possible (done on both). Subtracting the measurement from bullet tip to ogive from COAl should give me CBTO. And if all done right I would expect that no matter what bullet you do this with they should always give the same CBTO as this is the measurement of the rifles chamber not projectile. BUT... the VLD gives me 2.185" CBTO and the hybrid gives me 2.216" CBTO!! So I am taking a stab at this (and this is my main question) the VLD seems to be more pronounced contact of the lands due to its secant ogive (therefore probably the better one to get the measurements from) and the hybrid has a tangent ogive so I probably can't feel it as well and end up pushing it in further and throwing my calculations out? Was planning on starting around .010" off the lands. Measured my magazine and it looks like I can squeeze up to 3" COAL max. [/QUOTE]
