Remington 700 .308 Varmit with an OAL of 2.87"

[bigjoe8565]

I wanted to determine the OAL for my rifle, so I purchased a Lee Collet neck sizing die and Hornady Bullet Comparator to help me determine the OAL. I neck sized fired brass putting enough tension so the case would hold the bullet, but loose enough so I could move it with my figers. My average OAL using this method measuremed 2.87". I then checked the dummy rounds using the bullet comparator and I'm showing it's hitting the lands around 2.24".

I know that 2.87 is significantlly longer than any book calls for, but I'm trying to determine if I followed the right directions to determine my OAL.

I'm sure this has been discussed numerous times, but any help or feedback would be greatly appreciated.

Coat the bullet with black magic marker and do the same...when the bullet is pushed into the case by the lands and then extracted, if the lands pull the bullet out a bit, you'll find a mark encircling the bullet where the case mouth reached. That way you can check and see if your length is correct. I have a rifle that measures 2.872 to the rifling.

I was attempting to find depth to the lands on my Rem 700 .308. I don't have the numbers with me but it was exceedingly long!
Found out after researching it on the forum that you will most likely not be able to load anywhere close to the lands with a factory Rem chamber. Im sure others with more experience will give more info..

You did not give the bullet. {168 SMK, 175 SMK, 155 Scenar, 155.5 FullBore,...} Each bullet has a different OAL to ogive mesaurement.

However, My remmy (and many others) have a very long throat. Mine measures OAL = 2.963 with 155 Scenars. This is way to long for magazine length loads to be anywhere close to the lands.

I'm using 168 gr Hornady AMax to determine my OAL.

I've used the Hornady (was Stoney Point) OAL gauge to measure my rifle. My 700 w/ 168 SMK ends up being 2.925, 2.940 w/ 178 AMAX. I would say your barrel's throat is shorter than mine so that's not too bad. I've been told this is common for Remingtons. IIRC, my rebarreled M14S w/ M852 chamber measured around 2.890

"... 2.87 is significantlly longer than any book calls for,"

The book doesn't "call for" anything, that's just the length they used to develop their data in their rifle, it's no more a law than the powder charges they list.

Mine mics like fngmikes. 2.940" for 178 A-Maxs. Pretty long but they still work in the AI mags with the spacer removed and the receiver notched.
