[QUOTE="kiwi49, post: 1904509, member: 82514"] From what I've seen and read here and in other posts/forums - in all of the information, given freely, is this. Bullet jump, powder, brass, primers, technique, posture, range shot, weather at time of the year - can have varying degrees of effect. Just one thing I don't see mentioned here, is the freebore of the 243. I'm guessing it maybe a custom barrel? Jud96 - there's a lot of CBTO change from touching lands to 0.090"-0.100" off the lands and preserving powder space in the case. Can you enlighten me please, as the process sounds well reasoned and has some barrel accuracy life challenges made easier to live with. TIA. PS - I load AR2208/Varget in 308W/7.62x51, and find (for 155gn VLD type bullets), that any jump greater than 0.050", starts seriously compressing the powder column. To the point that CBTO becomes quite variable. Using 45.5gns powder in Lapua once fired to chamber brass (originally virgin at first loading). [/QUOTE]
