Page 4: Loading Data
LOADING DATA Use only laboratory tested reloading data. We highly recommend the current Speer Reloading ® Manual. OBSERVE ALL WARNINGS ABOUT THE USE OF MAXIMUM LISTED LOADS. WORkING WITh CARTRIDGE CASES • Examine empty cases to be sure they are in good condition before reloading. Thin, split, deformed, or badly corroded or pitted cases may be structurally weak, and result in a dangerous condition. -
Page 5: Main Features
Adjustments made using the large poise on the main beam, adjust from 0 to 1000 grains, in 20 grain increments. The medium poise on the top, adjusts from 0-20 grains in 1 grain increments. The small poise on bottom, in line with the main beam, adjusts from 0 to 1 grains, in 0.1 grain increments. The M1000 utilizes magnetic damping to eliminate unnecessary beam oscillation. It features a rugged die-cast base with a large adjustable leveling foot for extra stability on the bench. Self- aligning ceramic bearings support the hardened steel beam pivots to guarantee sensitivity to 0.1 grains. - Page 6 Photo 2: Beam placement Photo 3: Placement of pivots onto ceramic bearings Photo 4: Place pan support onto shackle Photo 5: Place pan onto pan support...

To accomplish this, remove the pan support top from...

The poise run is from 0-1000 grains and the equally-spaced notches divide this distance into 50 equal parts so that each subdivision is equiva-...
- Page 11 Photo 17: Main poise set on zero To increase weight values, move the poise to the left and line up the indicator with the desired graduation. Always make sure the pawl is seated in the notch. For example, the correct setting for 160 grains is shown below (Photo 18). Photo 18: Main poise set at 160 grains Do not attempt to set the main poise at any position except firmly seated in a notch.
- Page 12 Photo 19: Medium poise set at 14.0 grains hOW TO USE ThE SMALL POISE (1 GRAIN) The small poise functions the same as the large poise. This poise run is from 0 to 1 grains and the equally spaced notches divide this distance into 10 equal parts so that each subdivision is equivalent to 1/10th (0.1) grain of weight.
- Page 13 Photo 23: Bottom pointer at 0.5 grains below reference target load MAGNETIC DAMPING The M1000 scale is equipped with magnetic damping which causes the beam to come to rest quickly without affecting sensitivity or accuracy. It operates on the principle of a permanent magnetic field resisting the motion of a non-magnetic, aluminum damper vane attached to the beam.
- Page 14 Add powder to the pan until the beam balances. For efficient and effective results we recommend using an RCBS® Powder Trickler-2 (sold separately). When making repeated weighings in this manner, avoid weighing errors by making sure that the poises remain in their correct positions and are not accidentally moved.
