[QUOTE="AntiPattern, post: 2048717, member: 114161"] This information and lengths I ams spouting off are for my 6.5 Creedmoor. Ok. What I figured out is that some of the bullets I was using to reload would measure 2.805 but the CBTO (Base To Ogive) measurement was at 2.30 which is the jam point on my gun. I actually had to shorten some to get the pressures to go down to normal. So, I have learned to measure both COAL and CBTO when I start using a new bullet. When I loaded up some 156gr Berger Elite hunters at 2.805, the CBTO is way back at 2.10 and if I push them to my sweet spot of 2.20 which is where I want my CBTO, they are too long to fit in the mag and the COAL is around 2.90 so I would probably end up loading one at a time if I wanted these or push them back from my current sweet spot of 2.20. 140 gr SPEER, I have to load to around 2.72 COAL to get a 2.20 CBTO. There are HUGE differences between bullets which is something I wasn't aware of as a newby. Be sure you aren't jamming the barrel if you are measuring COAL. Depending on which bullet you use, one could be jamming and one could be too far back on CBTO while the COAL is the same length. I really scratched my head on this one for a while folks. Thanks for all the info along the way! [/QUOTE]
