Stalking on extremely steep deer forests such as his own at Glencassley, Lloyd was in search of a \"canyon rifle\" cartridge that would shoot exceptionally fast and with a very flat trajectory across deep valleys and over distances out to yards ( m) and more, to make range estimation less critical for accurate bullet placement, and to deliver a hard-hitting bullet weighing a minimum of 100 grains.
