Early 700P twist rate.

[desertrider]

I recently purchased an older 700P with a 26" barrel.

Searching the web I came across several different sources stating a 1-12 twist rate.

I decided to call Remington to find the exact date of manufacture based on serial number. I was told a manufacture date of 2000. I then asked what kind of rifling and twist rate, to which the reply was standard rifling (not 5R) and a twist rate of 1-10.

I know that current SPS models with the shorter barrel is 1-10, but I've always understood that the longer 26" barrel 700P used the slower twist rate of 1-12.

Anyone here have an older 700P with 26" barrel with documentation that states twist rate?

what caliber?

i have one in 308, 26" bbl with 1/12. purchased...i think it was 2012/13

Just stick a cleaning rod with patch down the barrel, watch a rotation, and measure.

I have one I bought in 2012....its 1/12 Order No. 25709

Sorry about that. It's a 308.

Seems like the general consensus here is 1-12 for the 26" pipe also.

I should have thought of that. I know what I'll be doing tomorrow.

If the Order No. is something I can get from Remington when I supply the serial #, I'll call back and see if it includes model specific details like twist rate and barrel length.

Thanks for the replies.

I'll bet it's 1-12 twist. Called it.

But it really shouldn't be a concern. Nothing wrong with 1 in 12 for a .308. You're not going to be flinging 215 gr bullets out of it.

Don't know about all the generations, but circa late 1990's, I had one that was 1-12. Regardless, 1-10 will do you just fine.

Well, checked it this morning. Definitely 1-12.

Not sure why the Remington rep on the phone insisted the rifling was 1-10. I know the SPS is 1-10, but since we were specifically discussing an older 26" barreled 700P there's no excuse for him to give inaccurate info.

Just an old salesman's trick. If you don't know something, just sound confident.

True. But now that I know for sure it's a 1-12 I'll focus my load development in the 155gr~168gr bullet selection range.

In 2000, your rifle was probably a 700PSS.
That would be a 1:12 twist with a 24" long barrel.
Around 2006, the PSS was replaced by the 700P.
That should be a 26" barrel with a 1:12 twist.

Measure the barrel length from the center of the gas relief hole on the side of the reciever.
Does yours have a 24" or 26" barrel?

They don't know so they just look up the current info.
They might not have even looked up the correct barrel length as the length effects what twist they use.
26" 308's get 1:12.
24" 5R 308's get 1:11.25
20" and 22" 308's get 1:10

26" 1:12 308's usually run 175's very well.
You don't need to worry about 175's unless you had the barrel shortened to 20" or if you are running the velocity lower than common match ammo.

Most factory Remington barrels won't shoot 155's well.

+1

Or, for a more detailed explanation, start a patch or brush in the rifling. With a sharpie, mark a line along the top of the rod for about 14". Mark a ring around the rod at some repeatable point (where it enters the receiver, rear of the stock, whatever you choose.) Push rod into the bore until the line along the top is back at the top. Mark another ring at the point you used the first time. Remove rod and measure the distance between the rings.
