[QUOTE="MagnumManiac, post: 980296, member: 10755"] You are correct in thinking that there is a built-in safety margin in your chamber, it is usually set around .035"-.040" longer than the trim-to length, as you discovered. ALL chamber reamers have about the same amount, whether custom, match or standard. I have only ever run into trouble once, in my 25-06, cases were .050" longer than MAX CASE LENGTH, fired ONE cartridge, gas and smoke came out of the bolt raceways and the bolt was locked SOLID, eventually got the action open, no primer to be found! The case had a very swollen head and where the case mouth was pinched was quite discernible. I do have this case on my loading bench as a reminder to ALWAYS check my SIZED cases for length, I have a photo of it, but can't post pics from my tablet for some reason. Good shooting to you. Cheers. gun) [/QUOTE]
