size, I have a hunch that optimum accuracy<br />

in the .44 Mag. will come with cast<br />

bullets held to bore diameter. One will<br />

have to slug his gun's barrel to be absolutely<br />

sure of the groove diameter, of<br />

course, as machining can vary; but the industry's<br />

standard indicate a 0.429-inch<br />

groove diameter for the .44, in which case<br />

0.430-inch would be slightly oversize. This<br />

idea of holding bullet diameter at bore diameter<br />

is especially needed if reloads are<br />

going to be screwed to maximum pres-.<br />

sures, because oversized bullets would suffer<br />

acute deformation if kicked from behind<br />

by intense pressures and rammed<br />

into the rifling to be swaged down at<br />

breakneck speed.<br />

If cast bullets are to be driven at magnum<br />

speeds, a gas check is suggested to<br />

protect the bullet's base from heat and deformation<br />

pressures.<br />

Although much attention is focused on<br />

jacketed bullets and cast slugs, there are<br />

two bullet concepts that lend themselves to<br />

excellent hunting performances in the .44<br />

Magnum: the Speer half-jacket and the<br />

Lyman "Composite" bullet. Ideally, a<br />

hunting bullet will expand (mushroom) on<br />

impact, and that requires a relatively soft<br />

nose. By itself, that requirement could be<br />

easily met by casting soft bullets. But magnum<br />

velocities complicate matters and if<br />

one is going to push high-speed hunting<br />

bullets through the .44 Magnum, he must<br />

make some provision to eliminate leading.<br />

This is handled nicely by half-jackets and<br />

composite bullets.<br />

SPEER HALF-JACKETS<br />

Speer makes two excellent half-jackets<br />

for the .44, a 225-grain HP and a 240-grain<br />

soft nose. Both have the Keith-style design.<br />

The 225-grainer can be moved to 1,525<br />

f.p.s. by 26.01296 or H-llO, while 23.2/<br />

2400 and 18.0/Blue Dot give it about 1,500<br />

fp.s. the 240-grain Speer half-jacket does<br />

roughly 1,400 fp.s. ahead of 24.5-24.71296<br />

or H-llO, and 22.2/2400 registers about<br />

1,375-1,400 f.p.s. Half-jackets should be<br />

crimped so that the roll crimp impinges on<br />

the leading edge of the bullet's jacket.<br />

Half-jackets are not suggested for reduced<br />

reloads and should always be fired at maximum<br />

or near maximum velocities; for<br />

there is a possibility that, given low gas<br />

pressures, the jficket may remain stuck in<br />

the rifling as the lead core continues.<br />

The Lyman composite bullet is an innovative<br />

way to give cast bullets both a hard<br />

bearing surface to eliminate leading while<br />

also providing a soft nose for expansion. It<br />

is a 2-part bullet, in fact. The cylindrical<br />

shank/base segment is cast separately of<br />

linotype for optimum hardness; then, the<br />

nose portion is also cast independently of<br />

pure lead, and the two are joined with 2­<br />

part Epoxy. In.44 caliber, the Lyman composite<br />

bullet weighs about 245 grains, and<br />

it can be reloaded to high speeds because<br />

ofthe base portion's hardness. Twenty-two<br />

and a half grains of 2400, a compressed<br />

load, will give it 1,400 fp.s. with a Remi-<br />
