An excellent source of diminished-load data is Lyman's cast-bullet manual, which may be employed for both equally Solid and jacketed bullets.
The thin, rectangular canister usually takes up considerably less space in my powder storage than currently’s rounder plastic accurate 5744 load data jugs, so when it’s depleted I refill the can.

(In the event you don’t believe this, Look at a variety of sources of data for Solid and jacketed bullets. The maximum cost is Usually fewer for Solid bullets of the same body weight, although muzzle velocities will often be equivalent.)
A further good resource for definitely- lessened data is Lyman’s Forged-bullet guide. Its loads also perform with jacketed bullets due to the fact, contrary to what numerous handloaders think, jacketed bullets actually result in fewer tension Along with the similar loads, due to the fact they don’t seal the bore as fully as softer cast bullets.
