i was on the remington website they list a 6mm rem MAG for a couple years in the 60's, what was it; case, performance ect . ive never seen or heard of one

I would venture that you're thinking of the 6.5 Rem Mag.

For a couple of months in 1962, Remington roll stamped the 6mm Remington 700 barrels "6MM REM MAG". None of the barrels got out stamped that way, that I've heard of, but there were a number that left Ilion with the "MAG" overstamped with an "X", so the barrels look like 6MM REM XXX.

I have a 700 ADL 20" barrel chambered in 6mm with those barrel markings. SN 579xx that has a barrel code indicating a March 1962 production.

Actually about a year ago I saw either a Rem. 7400 or 7600 for sale on gun broker that had the barrel stamped 6mm Mag, I would not have believed it had I not saw the picture showing the stamp. The seller stated that it was actually a 6mm and not a mag. I don't know if he ever sold it but he was wanting alot of $ for it because of the Mis-stamping.

yeah this really got me curious, the rem site lists 6mm mag in model 700 1963 - 66 i believe it was, and its right next to 6mm in their listing of calibers. i was looking up info on the 6.5 in 660 when i found this . must be a short period rename like the 280/ 7mm express

im guessing your bbl code is AI for the 6mm

According to John Lacy's book on the Remington 700, the "6MM REM MAG" stamp wasn't supposed to be used at Ilion, but some barrels were stamped that way and were then "X'd" out when the decision was made to call the cartridge the "6MM REM", rather than the "6MM REM MAG".

The barrel production code on my rifle is "LK", February 1963. I know, "AI" meaning Ackly Improved, not March 1976/1988.

ill have to get that book
going by eariler post AI woulb be mar 62 .
LK would be feb 64
code is first letter month second is yr.
blackpowderx- b= jan x=dec year starts 1954 =A
anyway thanks for info

Hah, i decided to check my 6mm which i am cleaning right now, and low and behold there it is.

but hot damn i didn't know the rifle was from 1962, it shoots .4 inch groups at 100 yards with a 90 grain Nosler BT and 45 grains of RL-19.


Love my 6mil, makes things like full sealed soupcans turn into bombs.

Good logic, except that Remington didn't use all 26 letters of the alphabet until after the date range in question.

Remington used the year codes A thru Z from 1954 thru 1975, but they omitted "I", "O", "Q", and "V" during that date range. I, O, Q, and V were used for 1976 thru 1979 and then Remington started over with A.

1980 thru 2005 used A thru Z.
2006 started at A again.

i may have to rewrite my codes but i have a 660 with XQ and they were discontinued in 71. and i would like to know what yrs the 700 used the flat saftey ( the part of the lever you push) and when did they go to round, alsowhat years did they use stainless bbls that were coated with i believe iron oxide then blued . if you have a book you get good rem info from give me title and author and i will get it . im not that good on computer and some webs drive me nuts

I don't think so!

rem renamed 244 to 6mm and has been that way ever since i guess, rem 280 was renamed 7mm express now its 280 again. so the question is if some 6mm's were stamped 6mm mag then xxx out. where did this thinking come from. and rem lists this caliber on their site, now im not a historian or i wouldnt be asking. was 6mm mag some attempt to make 6mm more appealing than 243 as it appears not to be a new cartridge development at the time according to the posts on this site

I have seen several of the early 700 6mm Remington Mags with the MAG XXX 'ed out after the barrel had been blued. All of the markings except the XXXs were from the original roll marking. The barrels were all 20" long.

the 660 i have is XQ and the 660 was only produced from 68-71 according to the rem history site. this is not a 600 mohawk
now my 700 in 6mm is BR

The barrel code on your Remington 660 is a mystery to me. Perhaps only Remington would know why a rifle made between 1968 and 1971 would have a post-production barrel code.

There are only 2 reasons that I could think of, off the top of my head, for your rifle having a 12/78 assembly code:

1. Your rifle was sent to Remington and rebarreled. The barrel codes are assembly date codes, so a rifle rebarreled by Remington would likely have an assembly code that matched the rebarrel date.

2. Your rifle was rebarreled with an 18.5" 600 Mohawk barrel. The 600 Mohawks were in production between 1972 and 1979, so a barrel with a 12/78 assembly code would fall into that range. I've bought and sold several 600 Mohawk barrels over the years and spinning a different barrel onto a Remington 700 family action is pretty easy work.

A concise answer to your question: Remington decided that it had made a mistake in giving its .244 a 1-12" rifling twist, which would handle spitzer only up to about 90 grains. The competing .243 Winchester had a 1-10" twist which would handle the popular (for deer hunting) 100 grain spitzer. As a result, Remington's advertising and promo people decided to rename the .244 and give it a 1-9" twist to handle any bullet. At first, they decided to cash in on both the metric designation (which had worked well in their highly successful 7mm Remington Magnum), and to ride the coattails of the "magnum" craze of the day. Just as they had called their stretched .222 a ".222 Magnum" without it having any kind of belt on the case usually associated with the term "maganum", they at first decided to rechristen the .244 the "6mm Remington Magnum". However, the rising sophistication of shooters, who were by that time voraciously consuming a raft of information from relatively new gun magazines, cause something of a "naming backlash" since the cartride had no magnum belt and was otherwise identical to a cartridge that had been identified for years as a non-magnum. As a result, after an initial tentative trial run renaming the .244 the "6mm Remington Magnum", the company copy writers simply dropped the magnum and started calling the cartridge the "6mm Remington".

The long and the short of it is that the .244 Remington, 6mm Remington Magnum, and 6mm Remington are all the same cartridge. The difference is that the SAAMI standard rifling twist for the "English" designation is 1-12", and the two Metric designations (including the now renounced "magnum" one) use a 1-9 twist.

As other posters have conveyed, a few guns stamped "6mm Remington Magnum" either left the factory that way or had the "magnum" x-ed out to comport with the officially revised designation. I'm surprised that the Remington website still acknowledges the "6mm Remington Magnum" in that the company propaganda tried to bury the initial renaming faux pax in a flurry of press releases and advertising.

I wonder if Remington ever made any "6mm Rem Mag" ammo, with a "6mm Rem Mag" headstamp?

Never saw any, but that doesn't mean that it doesn't exist.

well i guess the mystery is solved on the 6mm mag . thanks all for the good info
and to 260remguy im willing to bet the XQ on the 660 was a screw up on the part of someone doing the stamping process. i once had a smith 586 that missed the heat treating process, the bbl. blew off at a shooting range . ripped the threads rite out of the frame. smith replaced it . so you can never say never
