There are measurements that need to be taken.

The J broke on one spoke so I removed it and measured it. I come up with 296mm but wanted to ask.

I am re-building wheels right now for my 78 G.S. The spokes that I took off the rear (Tipo hub, Ambrosio clincher rim) had 295-6 for both drive side and non d.s. My bike didn't come with a front wheel.

How huge are your hub flanges? I'd expect a number much closer to the 296 that the O.P. reported.

Next question, where can I buy a few SS spokes and nuts?

I am pretty sure I had them replaced in 2000.
I noticed the spoke I pulled the end has been clipped off at the end of the nut. They are all like that. I assume the shop that did the work did not have the correct length spoke? Or is this normal?

If you have a reputable bicycle shop nearby, that would be a good starting point. Bring your wheel in. If they suggest you get a new wheel, say no. If they insist, tell them, "no thanks" and try another.

I just had the drive side spokes replaced on my 1977 Competition GS at my local bike shop. It cost less than $40 total. I had a derailleur (fall apart)fail that allowed the chain to jam the spokes and gouge them. The bike shop cuts and threads the spokes to length required. Joe

What is the correct spoke length for a '79 Raleigh Competition GS?
Depends on the paint color and height of the head tube.

That's your answer. they usually break right at the bend, which is close enough to where you measure from.

Post your location, odds are you're near other BF members. We like to show off our bikes, see yours, encourage you to buy more (we're a sneaky lot and like to spend OPM), talk about bikes, work on bikes, heck, I even use Bike Forums to recruit people to go on bike trips with me!

I had multiple thoughts in my head on what to post, that's more creative than some that I thought of!

Maybe we should start a recurring meme for non-sequitur replies. I nominate this:

a 265 spoke is about 10 7/16" that is really really short for a 700c or 27" wheel. unless deep deep aero rim.

to answer the original poster-
correct length spokes would NOT require the ends to be clipped. The spoke should engage the nipple fully or to the to the base of the end slot (Torrington have no slots- hex), a turn beyond is OK.
Assuming 3 cross or 4 cross, 700c rim, 36 spokes, high or low flange, things do adjust around. but for normal rims of the era or not aero deep section, the range could be roughly, and this is approx, 294-302
Rim brand and model means much +/- 3mm
next is cross and flange, they can +/- 3 mm
Drive side spokes on the rear wheel can be 1mm to 2mm shorter due to the wheel dish.

If the spokes are clipped and the wheel has a broken spoke on the rear wheel drive side.... I would rebuild the wheel. the original spokes were too long, (shop had limited stock, did not know/care)
clipping spokes reduces the amount of adjustment later. less threads to utilize. In normal circumstances, meh.

This reminded me- I bought a bike from the original owner whom had the wheels rebuilt by a shop local to him. It was at the time before 700c was popular for clinchers.
There was a period of time where there were many more 27" tire options around than 700c.
Wheels were built with 27" Super Champion Gentleman rims. Original were tubulars.
Tires were dead so I removed them and found the spokes were way short.
The nipple head was empty.
Not a good wheel.
So, I replaced the rims with 700c similar section rims. Perfect.
I got off cheap. And now, much more choices of tire in 700c than 27".

I agree %100 . Whenever I go to my local bike shop there seems to be another C&V type bike person who is just as passionate about bikes as me. We are an odd bunch, where my new bike shop is going is an industrial area and I am clearing a section of my shop to build up for bikes and memorabilia while continuing my tool grinding business. The neighbor asked my wife if I had always been a bike hoarder! I guess seeing all my vintage racers lined up where there used to be CNC machines seemed odd to her.

I was thinking about trying some Tannus solid tires.
I watched a few reviews and they seem nice although expensive.

Can anyone give me feedback?

My inflatable tire size is 700x25c, 16mm rim.
Tannus recommended 700x28c which I dont understand.

Also, why and when would a semi slick be preferred over a slick?
