North Fork 458 

The primary use for this bullet is in Ruger #1 rifles chambered for 45-70.  The lighter weight and subsequent higher muzzle velocities, together with the lower initial opening velocities of the bullet, makes the #1 a viable 200+ yard bear, bore, and elk gun.  The bullet will withstand anything that a 458 Winchester Magnum can dish out, but the sectional density may be a little low for initiating up close and not so friendly confrontations with a half-ton of brown bear.  That situation would be better served with the 458-400 grain bullet.
