1903A3 Remington 4/43 barrel
This may be a dumb question but how do I tell the number of grooves in a 1903A3 barrel? it is marked RA a bomb and 4-43
Looking down the barrel it looks like 6 grooves but I have always heard they were 2 or 4. I assume it is just try to count the grooves or the lands?

That's right, you look down the barrel to determine how many grooves the barrel has. IME, it's easiest to see what you're looking for when you look from the muzzle end.

Count the number of grooves.
Remington used a four groove barrel at the start of production. The Ordnance Dept approved the two groove barrels in Oct 1942. Remington had switched over to the simpler to manufacturer two groove by early 1943. Both two and four groove were used concurrently after that point. The Smith-Corona A3's used two, four and six groove barrels from two different manufacturers, High Standard and Savage (through HS). |

But some of those 6-groove barrels were used for replacement barrels, so a Remington '03A3 could well have a 2-, 4-, or 6-groove barrel.

Can you point me to some documentation on Remington A3 six groove barrels? I would like that for my data base. All documentation I have, Canfield and Harrison, say Remington A3's had four or two groove barrels only.
OP's barrel is marked RA 4-43, I doubt it's a replacement. I hope the OP posts back what he finds. |

You misunderstood what I said. I said that 6-groove A3 barrels were used as replacements, so ANY '03A3 could have a 6-groove REPLACEMENT barrel, just as ANY '03A3 could have ANY other REPLACEMENT barrel.
No, an original RA barrel would not have six grooves, only 2 or 4. Jim |
