Believe you can also use the early WW1 Vickers links for the 1915 Colt-Vickers in 30/06 for the .308. They are also pricey and hard to find. I've been lucky to find about 200 of these links and I use them for display with a WW1 Vickers and my 1917 Machine Gun Carts
I could not physically push a .308 into a 30-06 link.
Im sure I could force it, but it’s better to have the correct equipment. The pitch is different on the 30-06 link also. Much wider than the .308.
Feed block stroke was significantly altered in the SA .308 conversions accommodate the closer pitch of the SA links. The SA links are copies of the US M13 .308 M60 links but with the tail on top not the side as with the M13s as can be seen in the pic.
If you have a .308 SA Vickers feedblock, just cut off the tails on the M13s and insert cartridges to correct depth to function. FWIW
