Over all length
What is the best way to measure the chamber of a Rem. 700, to determine how long to make a cartridge, so the bullet is as close to the rifling as possible without touching it.
I have tried a dumby round with smoke on the bullet, but it does not seem very accurate.
Thanks

What you are trying to do is not an accepted loading practice.
Case length, and overall length of the cartridge, should be determined by data in your reloading manual. Deviations from published recommendations could lead to annoying, or dangerous, malfunction.

I take a bullet and cover it with a permanent marker. then just set it inside the case mouth by hand. Then insert the round into the chamber and close it. Remove the round, (the bullet may be stuck in the rifling and need to be pushed out with a cleaning rod). The bullet will have a scar on it, where it was forced back into the case, and the scar went through the marker. Insert in into your seating die and set it down little by little, until that scar just disappears or lines up with the case mouth. From here, you may wish to shorten or lenghten in .001" increments to find the most accurate OAL. Sometimes it is touching the rifling, sometimes as much as .015" back.
Of course, as nmeyers stated, this is not the recommnded way of doing things. Get good at reloading to SAAMI specs first, and later on try tricks to get better accuracy. Never start with a max or near max load if you are against the rifling, if you have made a mistake, it can be a bad one for you and the gun. the first words on the www.accuratereloading.com site are,....."inherently, loading ammunition is dangerous" so always error to the side of caution.

Do you resize the case first, or use a just fired case?0 -

STONEY POINT MAKES A OAL GAUGE THAT YOU CAN BUY FROM MIDWAY,MIDSOUTH OR MOST OTHER SUPPLIERS.YOU HAVE TO BUY A SPECIAL CASE FOR EACH CAL. YOU NEED.
SOME BULLETS YOU CAN'T GET THE MAX OAL.BECAUSE THEY WON'T FIT IN THE MAGAZINE. THEY ARE JUST TO LONG0 -
Clair, I use a resized case, as I am only looking for an OAL that will put me on the rifling or very close, and I would rather have a case that feeds nicely for this purpose. The VLD (very low drag) bullets will often not fit in the magazine when seated out to the lands, but many bullets have an ogive/taper that will allow them to be fed from a magazine. It is quite often the heavier bullets for each caliber which won't due to the lenght they must have to obtain the weight. An example is a 150gr bullet can be seated out and fed from a magazine in a 7mm mag but the 175 would probably not, due to the aforementioned extra length. All bullets have have different tapers and ogives. Get what they call a bullet comparator and you will see what I mean. It looks like a big "nut" with a hole in each side for different calibers. When you take a projectile and stick it in the appropriate caliber hole, some will go in further and some will not. That shows the difference in tapers/ogives between projectiles of the same caliber.
