Greetings all,
I do find it amusing that a fast twist .270 WCF is greeted with so much fuss when Wilhelm Brenneke had completed all the work by 1917 in his 7x64. This cartridge has projectiles up to 174 grains stabilized by a 1 in 220mm twist (8.66"). The .270 was clearly a rough copy of the earlier cartridge. Both the .270 and 7x64 plus the .30-06 were all descendants of the 7.92mm (8 x57) from 1888.
Regards Grandpamac.
