Help deciphering target barrel markings

[jonh172]

Hey guys, here’s the barrel I picked up for my L42 clone.

Can you guys tell me what all these markings mean? The internet has helped some but I’d like confirmation.

Thanks!

A 1970 barrel manufactured by Enfield.
Barrel part number CR1470

Two arrows 'back to back' with the S = Sold out of service (surplussed)

There's something seriously wrong with your breeching-up job there. The breeching washer should be sitting on the shoulder machined in the barrel and there should be no gap between the rear face of the barrel reinforce, the washer, and the front face of the receiver.

Presumably the inside diameter of the washer is too small to fit onto the shoulder. Your choice which one to alter!

I noticed that too, but presumed it may have been unscrewed a turn.....

It is perhaps worth confirming to the OP that he has the correct pattern barrel for a L42A1; the CR1470 Ministry of Supply part number is exactly as one would find on a genuine L42, & 1970 was the first year of large scale conversion.

[Surpmil]

Yes, and those sale marks were not applied to all them from what I've seen around here. Perhaps only the earlier ones?

A very popular and well-regarded barrel in the target shooting world, with a long life too. Different twists were available, so that might be worth checking.

Thanks guys!

The barrel is not installed yet but thanks for looking out for me!!

It times at almost 45 degrees so I will be shaving a few thou off the shoulder before cinching her down.

This is exactly what I was hoping hear thanks Roger!

Thanks Surpmil,
I’ll figure out the twist and report back!

It is also a 4 groove barrel, not sure if that was standard??

Yes, I believe they were all four groove. IIRC the lands have a noticeable bevel on the outside edge which could be mistaken for wear at a glance. Pretty sure they came in 10, 12 and 14:1 twists with 12 being the military pattern. They could also be bought without any threads or Nock's Form.

I'm sure there are people here who have more precise info.

What loads are you planning on using in this rifle.

What loads are you planning on using in this rifle.

I Haven’t even begun to think of what I might use yet.

I do like flat based bullets for up to 675y.
But I also like Hornadys ELD line up.
I’m a certified “fanboy” of the 147eldm’s in my tikka t3 varmint in 6.5x55!!

I will see what twist I have and work around that.
