[QUOTE="25WSM, post: 2072435, member: 38048"] Well first of all seating a bullet long and jamming it in and closing the bolt is going to give you max jam length. This can be as much as .025 thou from zero jam. And it won't be consistent. That's why so many have said to use the wheeler method. It will be the same number each time you do it. Very repeatable. All that max jam tells you is how long your cartridge is when the bullet jams so hard it quits moving forward and the case slides up the bullet. The reason this measurement is so vastly different each time is the bullet is stuck in the barrel and sometimes it slips in the case before letting go and sometimes depending on neck tension will stay in the barrel and the case will come out with out it. There is absolutely no reason to not do the wheeler method. You don't need any special tools. Except to take the firing pin unit out of the bolt. You probably already have that tool. Look up the wheeler video and try it. It's easy and works. Will get you your zero point number to work from. Shep [/QUOTE]
