Does this seem right to you

[pyplynr]

I'm loading for my factory R700 AAC-SD .308

I just bought a Hornady Lock-n-Load OAL gauge. Here's what I'm getting.

For a 175 SMK - OAL of 2.928 and 2.355 For the casehead/Ogive measurement.

For a 178 amax - OAL of 2.958 and 2.332 For the casehead/Ogive measurement.

2.928 and 2.958 seems real long when both my Hornady and Seirra book both say 2.800 OAL

Do you think that the barrel is chambered to deep?

Is that to the lands or a little off? Either way it doesn't really matter as my SPS Varmint is basically the same measurements as yours. The reloading manual gives you the SAAMI spec which is pretty much always going to be shorter than your measured specs. I wouldn't worry about it.

yeah that was into the lands. What would you recommend for the length, Mag length?? My mags are 2.900 so that would be a .058 jump for the amaxes and .028 for the SMK's. wouldn't that be too much of a jump?

How much of a jump do you think there is with factory ammo? They chamber MOST factory barrels deep for that reason.

If you are going to load long, then count on loading by hand.

If you want to feed from the magazine, as in hunting or rapid fire matches, load to the magazine length -about .062" Some rifles with factory chambers actually like a little long jump.

Thanks for the info. Only reason it was screwing with my head was that my 22-250AI likes to be seated about .007 off the lands. So .058 seemed like a mile.

Thats a remington for you!

You know, those projectiles should be giving you similar results. How many readings did you take (head to ogive) for each projectile type?

Typical Remmy chamber (throat, actually).

All Remington 308's should be nicknamed "Linda Lovelace" for their deep throats.......
