Mongo... if you plan on reloading rifle cartridges, make sure you get a press with compound linkage, and standard 7/8x14 dies...if you plan on reloading a lot, then I would suggest something like a progressive Dillon 550...if you choose a single stage something like a RCBS Rock Chucker... if you go with a single stage, you will do the same operation to a batch of cartridges (say 50/100)...size/deprime/prime... change die, bell/charge...change die seat/crimp bullet...you pre-set the dies and they have a lock ring to maintain depth, so only need to loosen and change
reloading press...I've had experience with only RCBS;CH, and Dillon
dies... 7/8 x14... carbide sizing dies... if you shoot a lot of autoloading cartridges would suggest a Lee sizing die, as they size farther down the case... for rifle dies, you will need to lubricate...carbide bottle neck rifle dies are more expensive
powder scale....magnetic or oil dampened... weigh out charges from your powder measure (which drops by volume) to adjust the weight dropped by the measure...weigh out 10 charges and divide by ten... eg. ten charges weigh 42 grains, divide by 10, each charge is 4.2 grains) adds more precision than using the .1 grain scale....mark a place on your reloading bench that is as level as possible, and sit scale in the same place...do not use on top of a styrofoam packing box, as static charge may affect reading...calibrate with factory bullets of varying weights if you don't have a calibration mass pack...if you go with a single stage, the powder measure is a separate piece of equipment
powder measure... rotor or sliding bar types, allows you to adjust the powder volume...some of the rotating units have a tendency to "crunch" tubular powders...Dillon comes with sliding, RCBS a rotor
dial or digital calipers... to adjust the seating die, and get the correct overall cartridge length
primer flipper tray...DO NOT look down into the primer tube while loading primers, a detonation could be deadly... wear safety glasses
case trimmer/deburring tool... if you load bottle neck cartridges, the neck will grow and needs to be trimmed... if allowed to get too long, when the bullet is seated and crimped into the cannelure, the shoulder can be pushed back, making the cartridge hard to chamber into the rifle....pistol caliber cartridges shrink
case tumbler... if you use found on range brass you might invest in a tumbler to clean brass... not really necessary
propellant... most intermediate burn rate shotgun powders work well for pistol calibers... a 12ga will use about 5x the powder a pistol cartridge does.... I use Winchester ball process powders, as the graphite coating produces a cooler burn, and less deformity on the base of the bullet...the base controls the accuracy... I like Win Super Target (WST) and Win Super Field (WSF)... they can be found at good prices at trap or skeet ranges
shotgun...used to load on a MEC Grabber, but with the price of shot increasing, can buy promotional 100 packs at non competitive rate for me...only shoot 3 gun and not too much sporting clay
general suggestions
stand up, get a roller handle.. helps prevent tendonitis of elbow
place a light over the charging station, and look into each case... if single station is used, check a complete tray for charges, for progressive loaders check the height of powder,and if you have a case feeder, that the new cartridge doesn't have any debris in it....a double charge on an autoloading cartridge is pretty easy to spot, not so easy with a tall cartridge like .38/.357... an undercharge, typically a small charge in a large volume case... where the entire propellant charge is ignited at one time..does not burn progressively but instantaneously ...is catastrophic
lead is poisonous... dont eat, drink while reloading.. wash hands
stop if you are interrupted by someone
I currently load on a 1050, bullets are 147grain 9mm from Delta Precision, WSF....you will appreciate the ability to produce custom loads, using premium components for certain situations
good luck
