I need help IDing a remington 700 barrel in 6mm REM. This is a heavy barrel, over all length, from the threads to muzzle is 27 1/4 of an inch. On the left side it is marked 6mm REM with a diamond mark immediately to the right of this. On the right side, it is marked R (as in registered trademark) with REP (Remington Peters?) in an oval. It is tapped for rear and front sights. It weighs about 5 pounds. I did one rotation in 14 inches with a jag, so I assume the twist rate is about that. It has a very slight taper. No recessed crowning of the muzzle. The rifling appears to be strong, the threads aren't buggered and the chamber looks to be very clean and crisp. Is this a factory take-off? Any info is appreciated. I have no use for the barrel, and am looking to trade/sell it. I handload for .303 brit, Mosins and am a blackpowder/rendezvous enthusiast.
6mm barrel sounds like a varmint barrel but the twist sounds different to me i was thinking 1-10 or 1-9 is what rem put in the 6mm
<<On the left side it is marked 6mm REM with a diamond mark immediately to the right of this.>> I think the diamond mark would be the assemblers stamp if it is on the left side, they all have their own stamp. Is there any letters or numbers? If it is a factory barrel there should be 2 letters that would represent the date code. <<On the right side, it is marked R (as in registered trademark) with REP (Remington Peters?) in an oval.>> "REP" Stands for "Remington English Proof" Which means that a Proof round was fired through this barrel and it did not explode with the eleveted charge. Is there a triangle with a letter in the middle? <<It weighs about 5 pounds. I did one rotation in 14 inches with a jag, so I assume the twist rate is about that.>> Did it come off a M/700 or a 40X Remington not that it really matters, do you have the action? The 6mm Rem was developed to compete with the .243 Win, the early versions had to slow of twist rate to effectively stabilize the bullet weights for which this Cal. was intended for deer size game, Remington later changed the rate of twist to about 1 in 9 if I remember correctly for this reason. It sounds like you have a varmit barrel. Augustis
I would say that it is most likely a barrel off a Remington 40X because the standard length for the 40X barrels is 27 1/4" Since the 40X can be ordered with a bunch of different options from the Remington Custom Shop, the slower twist rate could have been ordered for use with lighter weight bullets.
Gee, I wish I had the action! When I was a youngster, I got my first rifle, a Sako Mosin Nagant (a rebarreled 91/30). My father and mother were hard workers, and I worked a paper route to supply myself with ammo! What we weren't was wealthy... and I'd see the guys at the range with their Model 70's and Sako Super Deluxes. I always wanted a rifle like that, but never could afford one. So I just concentrated on what I could afford, and now that I have grown up and have the means, I just kept on collecting Nagants and Enfields. I don't hunt with a centerfire rifle; I live in a shotgun/muzzleloading state. I stopped enjoying deer hunting with shotgun after a few seasons.. the part of the state I live in is OVERRUN with deer, and it was more like "waiting" that it was hunting. So I got into archery and muzzleloading. My friend, Frank, is a lot more knowledgeable about barrels, twist rates and gunsmithing is general than I am, came over this evening and examined it. I must have made a mistake with the twist rate because he got a different result that supports the 1:9 twist. He couldn't ID it as a 700 or a 40X, but knows someone who could. I'm following up on it. I try to learn something new.. and today I did. And I thank you all for the help. Now if I can just find a good home for this barrel, I'd love to swap for anything I could use for my own hobby :Enfields and Mosin-Nagants and their respective accoutrements. Gentlemen, I hope you have a great holiday!
