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 />
