Reloading Question - OAL Measurements

[Steinmaster]

Very good information. Thank you for taking the time to explain this. I measured my Remington 700P OAL to the lands and I do not have enough room to seat the bullet (SMKs and AMAX). Looks like the throat length is pretty long. Looks like I will seat the bullet to .308 minimum and go from there.

Out of curiosity, with say a 168 SMK touching the lands - how long is the OAL of the loaded cartridge?

Using the Hornady OAL gauge, I measured 2.339 off the ogive. If I were to use this minus .020 inches, there is not enough bullet left to adequately seat (.308), so I just used COAL from reloading manual. I'm getting superb accuracy from the SMK by the way.

What is the total overall length of the loaded cartridge? (Base of case to tip of bullet?)

Wow and that is new factory barrel?

Yeah. Brand new. I've had some other forum members say Remingtons have longer throats. I was surprised when I measured to the lands. The gun shoots 0.5 MOA at 100 hundred years so I'm not going to do anything to it.

Thats stunning - I use an Obermeyer 308 reamer in most of my 308/762 bolt guns and to give you an idea / comparison - with a 180 SMK (old style) .005 into the lands - my aprox OAL is 2.840". My son has a Remy 700 SPS in .223 and it has an astoundingly short throat (probably a straight .223 Remington) - I'd love to figure out what goes through the minds of Remy engineers when they spec a reamer for consumer guns.

I'm waiting for my GA Precision .308 bolt gun. Should be interesting to see what the measurement is and whether I can play with the OAL.

in general, SMK and Amax are usually very jump tolerant. It's not unheard of for them to jump .110+ and still group very well.
