[QUOTE="SteveBurton, post: 1260708, member: 59541"] I have a factory Remington 700 in .243 Win. In the pursuit to get the best accuracy and to limit throat erosion, I measured the chamber length. I did this with a brand new case that was FL sized and a Sinclair Chamber Length Gauge. I found the chamber in my rifle to be 2.080". The maximum case length for a .243 Win is 2.045 with a recommended trim length of 2.030-2.035. That seems like a lot of free space in front of the case to me but I would like some more knowledgeable reloaders to comment on this. The .243 is notorious for case stretching and throat erosion. Will this free space contribute to throat erosion? Should I let me case necks grow in length to fit my chamber? What should I trim the neck length to? Thanks in advance for any replies. [/QUOTE]
