Remington .308W Throat

[BV700P]

I 've got a Remington 700P in .308W with about 300 rounds through it. I measured the OAL with Hornady's OAL guage and found that with the bullet (155 scenar) just touching the lands it gave me a COAL of 2.960. However, my max COAL is actually 2.830 due to the magazine well. That gives me a jump of about 0.130 which seems like alot.

Does Remington make .308W chambers with a long throat ?
Is a jump of 0.130 too much ? Hornady recommends 0.020 - 0.040.

Just shoot SMKs and don't worry about it, they don't mind jumping.

In my R700 SPS Tac. 155 Scenars touches lands in 2.991" COAL. I am making ammo with 2.950" COAL and have no problem with accuracy

Here's typical 100 yard accuracy out of my long throated Remington, with bullets seated to mag length and jumping about .150" to the lands.

The long throat typically results in lower pressure/velocity than a load "should" yield. It can also let you load more powder before reaching pressure should you be so inclined. If you understand how it changes the pressure dynamics you can make it into an advantage of sorts.
