Very much doubt the VC had any shortage of ammo that caused 'em to make teak bullets.
No offence to your buddy, but Korean vets have also claimed the NKPA had .30 Carbine bullet proof frozen quilted jackets.
Like 44 AMP says, there is such a thing as wooden bullets in 6.5 x 55, but it was nothing but blanks.
Years ago, CIL made a 12 gauge dog trial blank with a 2" wood fibre wad. Had the word 'BLANK' in big black letters right on the shell. Said 2" wad would go right through a 2 x 4 at 10 yards. Crowd deterrent baton rounds fire rubber balls and are only aimed at the legs.
