Happy to help. RE: British MoD L129A1 ammo selection.....

"the British requirement was for the Sharpshooter rifle to fire standard 7.62 x 51 L2A2 ball ammunition produced in the UK at Royal Ordnance Factory Radway Green (RG). According to Greg Felton from LEI:

“The ammunition criteria stated by the MOD was that the rifle was to be able to use both RG 155-grain sniper ammunition, plus M80 ball and tracer, including de-linked machine gun belts. In the end during their trials with the various competitors, they found that the 155-grain fired so much better than the standard ball that it was made the official issue ammunition for the weapon. As to what it is “matched to,” [Karl & I] designed the rifle to use both standard ball and 168-grain Match. With a 1:11.25 inch twist it works well with these weights, however, the heavier 175-grain projectiles need a faster twist for best results at longer ranges.”
