I am building from the ground up on a CZ550 Safari Mag. originally in .416 Rigby......I could use a 1/8" twist if I want to. Planning on having Kirby turn it into a .338 Allen Express.

Nothing wrong with that if you do go with a 1/8 and want ot hunt with it you could use some of my 280's or 300 grain hats...

MC,

If you are considering a 1: 8" twist, there are two 6.0 caliber, 265 grain, engraving-band solid copper 338 projectiles, which will be available for public release within the next three months. They will function well with a twist as slow as 9.5", but require the faster twist between 3,000 - 3,500 fps.

The target version will retail for ~$1.30 each at current copper prices. The hunt version has virtually identical trajectory, and is designed to peel open nicely in three distinct petals out to 1,500 yards, with full weight retention.

Best,
Noel Carlson

Noel, do you have a bore rider hunting bullet that would work with a 10 twist?

Dave,

None of my designs are bore-riders. There is a maintenance issue entailed with the use of these, which is entirely circumvented by an engraving-band bearing surface configuration.

A 1: 10" exit-twist falls just outside of the rate necessary to take advantage of the copper density value. For example, the 265 grain, 6.0 caliber, banded copper solid essentially matches the 300 grain Scenar in trajectory with equivalent muzzle velocities, falling .2 mils lower at 1,200 yards (~8.4"). It requires a minimum 1: 9.5" twist however, and barely fits into available magazines even in the Norma Magnum loading. Given that the ZA338/6.0-Cu costs 40% more than the Lapua, the only justification for it's existance is extremely consistent, single digit ES, zero fouling, high accuracy, and superb expansion properties of the hunt version.

It is only when a 1: 8.0-8.5" twist is used that the ZA338/6.0 can surpass the 300 grain Lapua in BC by taking advantage of 3,500 fps muzzle velocities, and at that point it makes much more sense to move up to the 6.5, or 7.0 caliber ZA. In this region, copper has the perfect density to properly fill optimal aerodynamic forms.
