Hello,
I measured the length of the throat in my rifle and it comes in at 2.906. Is this a safe OAL to set my handloads to? Is this excessive for a remington 700?
Any suggestions would be appreciated.
Thanks

My Lyman 49th Edition Reloading Hnadbook has the OAL of the .308 Win cartridge as 2.820", the brass is 2.015"
I hope this helps, but I am not exactly clear on what you are asking.

My Remington 700 VS in .308 measures 2.91 with a sierra 150 sp prohunter bullets. Your overall chamber length will between different manufactures bullet because they have different ogives.

every bullet will have a slightly differnt ogive ,having said this what will matter is where the bullet will first contact the lands a round nose would theoreticly touch before a spire point would but not as quick as a wadcutter and the spire point would theoreticly be longest of the 3

Thanks for the replies. It is my understanding that the less jump the bullet has, the more accurate the rifle is. If I load my bullet with an OAL of 2.900 is that going to be too long? I'm using a Sierra 168 Grain HPBT. Is this not safe? How deep do you have to seat a bullet?

Depending on the load, some powders you may have a compressed load, but I put the bullet in deep enought so that it fits the magazine and chambers. I tried many loads loads and seating of the bullets, and I am just slightly below the 2.82" spec for my M1A

Thanks for the response. I press the bullets in at that length for my M1A. I also have a remington Mil Spec and would like to load it one bullet at a time, so I'm not limited by the mag length. Can you safely load at 2.900?

If it fits and doesn't show signs of pressure, try a few rounds first.

You will just have to play with your overall length. Some guns shoot better with the bullet seated further away from the lands then they do closer.

I have taken the "science" out of which bullet does the best arguement. I buy a box of what ever brand that says they can do better, load them up and try them on my range.
My rifles vary a little too much to use one standard for all of them.

When I buy bullets, I do weight each one of them and have 3 different piles. Each pile goes to a different rifle. But I generally use a Sierra 168gr Match king and some Barnes 168 gr TSX bullets.
But knowing the bearing surface is dependent on what type of bore you have. I know how my rifles shoot with the two different bullets, when I tried some Noslers, the M1A was that good with, but my 40x did great.
