M1917 Barrel Trivia
During WWII two companies made replacement barrels for the M1917 according to General Hatcher in the March 1947 AMERICAN RIFLEMAN Magazine’s, ‘Dope e Bag ‘ column”
Hi-Standard (HS) made 61,250 – 4 groove barrels
Johnson Automatics (JA) made 81,571 – 2 groove barrels
FWIW

I have a new RIA marked 1917 barrel.

[Cosine26]

I have heard of those but have never seen one. Is it 4 groove? Is it dated? I have no onformtion on how many were made.

[chuckindenver]

Winchester made replacement barrels dated 9-19

[Devil Dog]

Were all the Rem, ERA, WRA barrels 5 groove?

[jjrothWA]

Yes the WWI barrels were modified from British spec to handle the Cal.30 ammo.
WWII barrels were made for both the 03 and 17 to the upgraded spec of _two groove rifling as it allowed faster manufacturing and meet accuracy sped.
HS did make barrel for the 17 only ( careful, I had been known to be wrong! :) ) using the four-groove specs.

Did see in 2005 a Rem 17 with a "19" date Win barrel. Didn't buy it for I didn't have the cash.

Yes the WWI barrels were modified from British spec to handle the Cal.30 ammo.


British: Bore diameter .303, Groove depth .0055

US: Bore diameter .300, Groove depth .0050.

I saw this thread the other day and remembered that I had a new 1917 barrel somewhere in the piles. It is a five groover, marked Eddystone, with a date of 12-18. There are other markings if a photo would help anyone.

I just found a mint, uninstalled 5-groove Winchester 1-19 barrel. A 95-yr old virgin. The rifling cutter marks are visible, the lands razor sharp. It's going on a D&T'd Winchester action for a modified military cast bullet match rifle. I will size a little over groove diameter - Can't wait to see how it will shoot.

My HS barrel is the best shooting 17 barrel I have seen. If I do my part it will put five together that I can cover with a 5 cent piece. If memory serves correct it is a 4 grove WWII production barrel.

[Fred Pillot]

I checked the Johnson barrel on my Remington M1917 and it is a 4 groove.

[Rick B]

Anyone have a close up of a Johnson Barrel as this appears to be one but I want to compare a good shot of the Flame. I see what looks like a light stamp "A" top and I put it on my early 4 digit. Rick B

Three rounds fired at 200 yards yesterday with Remington rebuild with JA 2 groove. The only limitation on mine is the "nut" pulling the trigger

Here are images of the flaming bomb on my 4 groove JA barrel that is on my 4 digit Remington.

[RC20]

I checked mine. Its a two grove.

The bomb looks like the rest.

The P is on the eft side of the barrel and at 90 degrees counter clockwise to what the Ferris picutre of the RIA P would be, same general locaiton distance wise from sight.

[RC20]

Add in that the crown is almost non existant. A very small re-bate more than what I think of as a crown.

Here is a picture of the marking on a new RAI barrel.28847
