Slow twists are uncommon today, but they still exist. 30 caliber cartridges designed for longer bullets have a 1:10 twist. Roundnose bullets are shorter for weight than sharp-pointed, spitzer bullets. Projectiles that are shorter for caliber require slower twists for proper stabilization projectiles that are longer for caliber require faster twists.
Rifling twist is expressed as a complete rotation per inches of rifling, as in 1:10 (one turn in 10 inches). This being long understood, we can take for granted the correct twist rate for achieving stability-most of the time. Of these, projectile length, or at least the bearing surface that contacts the rifling, is critical. The formula for determining a proper stabilizing twist considers the length, weight, and shape of a projectile. Rifling twist imparts gyroscopic stability to a projectile, enabling much greater accuracy than a smooth bore. Yep, it’s light for caliber, but it stabilized, and I’m able to push it to almost 3,200 fps with no pressure signs. My friend Kyler Hamman directed me to Hammer Bullets in Idaho, which makes a 67-grain 0.257-inch copper bullet intended for the old 1:14 twist. 250 Savage rifles were barreled with a slow 1:14 twist for the initial 87-grain load. I should have known that before 1920 all. I have dies, so I loaded a few 90-grain GMX, but if the bullets hit paper at all, they hit sideways. Thing is, I wanted to use it on the Central Coast, but there are no California-legal unleaded factory loads in. Between my eyesight and the irons, I’ll never know how well it really shoots, but it grouped just fine with 100-grain Hornady InterLocks. 250 Savage from my buddy Joe Bishop’s widow-clean, in great shape, flip-up aperture.
