what constitutes an abnormally long or deep throat?

My son and I each have bolt action 308 wins. Mine is a Savage 10 FCP (with 500 rounds down the pipe) and my son's is a Rem 700 (with less than 150 rounds). Measuring off the ogive with a Hornady gauge, (same lot of Hornady 30 cal Match HPBT), the Savage measures 2.2365" and the Rem 700 measures 2.3480". COAL's to bullet tips are Sav 2.8465" and Rem 2.9575"

Wow, that seems like a huge difference (0.1115"). No chance in this world of feeding rounds through the Remington magazine loaded to or near the lands. I measured with fire formed brass and closing the bolt on the bullet and with the Hornady COL tool and both methods resulted in nearly identical measurements (+/- .0005".

Is the Rem700's measurement to the lands abnormally long for a Remington manufactured barrel, or is that to be expected?

If you can load to the lands and it still fits in the internal magazine of a factory rifle it's not what most would call a long throat. That said, factory loaded ammo is going to be designed not to jam in a SAAMI chamber, so what may not be long to a reloader might be very long to someone buying off of the shelf. In that case some might say that if it's longer than SAAMI spec it's long. In a competition rifle, if you can load to the lands and still seat the bullet in the case it's not too long.

Based on my experience with both manufacturers the Savage's probably short throated while the Remington's EXTREMELY long throated.

Given that the 2 have the same twist , I have seen savage rifles with shorter leades . Remington's have been all over the place , take a low round count 700 in 308 from the 1970s and it'll be shorter than a modern production 700 in 308 .
Also if one is marked 7.62-51 , that change the specs even more .

Welcome to Mrs. Remington's chamber.

I guess this goes all thew way back to when we each purchased our weapons. I opted for the Savage with the expectation it would be more accurate than a factory supplied Rem, and understanding that after a lot of machining and upgrading the Rem 700 could/would eventually be more accurate. But damn, I did not expect the factory Rem throat would be so long as to prohibit the use of a magazine.

I just don't understand WHY Rem would under any circumstance deliberately machine a barrel like that. I mean, what could the benefit or reason be? Seriously, I do not get it.

Lawyers at work. Same reason the Remington triggers are so bad.

Yup lawyers. I was told 30 yrs ago Remington throated their 30/06 and 308’s for 200gr round nose bullets. That’s why the throat is so long. Today I think it has more to do with the lawyers.

The long freebore is not the reason why the R-700's accuracy is not as good as Savage's.

It's the quality of the barrel that matters most. Then the diameter of the freebore matters more than the amount of freebore.

One of my 300winmags is a hunting rifle. The most accurate load in it is with 130gr Barnes TTSX jumping more than 0.200"

You guys are slaying me, make it stop. If I ever wanted to respond to a thread its this one. But I must resist or the boss will toss me and deservingly so.

My one and only is a Rem 700 308 LTR 20" barrel , I shoot it only for benchrest shooting , the free bore was so much if I wanted to jam a round it would almost leave the case neck , so I stuck with the listed OAL for the bullet used ( 168gr Sierra HPBT MK ) and worked up a charge the shot well . After 4000+ rounds changed the barrel to a RockCreek M24 5R 11.27 twist 21" completely blueprinted , bedded , Jewell trigger set a 10 ounces , changed the HS Stock that came with it to the longer an thicker HS 700P stock . Very little free bore on the RC barrel , both barrels are tack drivers but the new one I can play with ogive settings .

in the 70's a certain Miss Boreman set the bar.....Linda Susan Boreman if mammary serves......

All my Remington’s seem to shoot. I must be blessed.

Show off , we all have one of those 3 shot groups , I didn't have the
B _ _ Ls to shoot 4 and 5

Must have been chambered by Harry Reems!

See 3 groups in the middle as explained.


Shot at 200 meters while comparing seating depths.

My brain says I don’t need to shoot 5 shot groups with the rifle, of course your balls may feel differently.
