Rem 783 and Savage Barrel Differences?

[hoz53]

Hello All--I have read and heard differing info about the difference between Rem 783 and Savage barrels. I see the manufacturers are selling separate barrels for each so their must be something different. I know the tenon threads are the same. So does the Rem 783 barrel have a counterbore and what are the other differences? Thanks Hoz

I'm assuming you are referring to pre-chambered barrels. I think the reason they differ is because of the design of the bolt head. Requires some
smithing to interchange barrels.

The rem 783 will interchange , just use REAL headspace gauges .
I've done about 16-18 dif rifles for myself and a few friends .
Originally , the rem bolt head had a deeper edge to face ( aprx .002-.003)
Deeper than the savage . But your still safe ON MOST pre fits .
One pre fit had a bolt head , barrel interference , that one required the barrel to be cut to give clearance .
Sorry for rambling , not enough coffee yet

I'm not sure I understand. Are you saying that the Savage Barrels can be fit to a Remington 783 with no modifications?

What is the bolt to breech clearance?
I have not found diagrams of the 783 tennon.

 

[Ggmac]

Yes same , the dif if any are in bolt nose to bolt face depth . If using HEADSPACE gauges , you'll be fine . I've done 7 rem mag to 338 win mag , 300 Weatherby , 30-06 (4) to 6.5 creedmore , 6 br , 308 win long throat , 8 mm mauser , 308 rem 783 to 6.5 Lapua (2) 6.5 creed . Also converted a few to left feed right eject .
Bolt nose may hit rear of barrel if you use the full length sized case as a gauge .
Pm me if any more questions

Barrel nuts and recoil lugs interchange also . The bolt heads DO NOT interchange .

Hi Riesel--yeah knowing the difference in prechambered would be fine. Thanks for the bolt head info. I don't have a 783 to check but I think I'll fix that soon.

Hi jfseaman. Yes I want to know the stuff you are asking.

Hi Ggmac. I read some of your other posts on this. Thanks for chiming in. I've got a savage but no 783 yet to compare it to. I plan to get one soon. I always use headspace gauges. I think you've provided me with about all the info I need. One more thing the 783 does not have a counterbore right? Thanks again. Hoz

 

[Ggmac]

No counterbore , it's flat like the savage NOT at all like the 700.

The 783 is a better rifle/action than the price reflects. Built a 6.5 Creedmoor on this action and it is a dang fine shooter with much better than 1 MOA out to 500 yards. You'll be pleased, especially if you snag the rebate.

Thanks Riesel- from everything I can find out I believe you are right about the 783 being a great value for the money. I will try one and see how it goes.

All this and not one direct reference to the term Chamber Protrusion...

The term refers to the distance a chambered cartridge extends out from the chambered barrel's breech face. This protrusion distance is based on the cartridge base recess in the bolt face and a factor for bolt to barrel clearance.

I watched a heated battle proceed on another site some years back about whether or not a Savage drop-in barrel would work with a Mossberg receiver and bolt. They will thread together, but the protrusion mismatch could result in a case rupture at the gap where the case is actually unsupported for a small portion of its length in that application.

Protrusion is a key measurement, and must be correct.

You are indeed correct sir, reference my reply #2 about some gunsmith (meaning qualifying) the barrel fitting.

Hi Jarhead After thinking about it a bit I edited this post. I thought when I posted the original question the only difference between a savage barrel and a rem 783 was the depth of chamber. I now know the rem 783 has no counterbore like a savage and the boltface to end of bolt nose dimension may be different. I dont know about chamber depth. I just stuck a go gauge in a savage 243 takeoff barrel so i could see how much case protrusion there is. Now that I know that, when I buy a 783 in .243 ,i will check the barrel the same way with the same gauge. Then i can compare. Thanks for bringing it up Hoz

 

[Ggmac]

Jarhead read my posts #3 and 5
And Mossberg will not fit a savage , your were referencing the Marlin / savage interchange !

 

[JarheadAZ]

Yes; and I defer to the actual professional's experience.

Greg

 

[Ggmac]

Da ! I still pay liability ins after 8 years of retirement , from almost 30 yrs of riflesmithing .
So how many Mossberg barrels have you tried to install on a savage ? Consider that the savage is a diff diam and tpi .

 

[Ggmac]

Thanks guys , sometimes I just have to vent !
