You wont go wrong with a Hornady Lock N Load single stage press. The lock and load inserts make it a snap to switch out dies. Buy an extra three pack of bushings. Horandy makes a great press. The RCBS rockshucker is an old standard, and you can get the Lock N Load conversion kit for these! You wont go wrong with either one of these.
For a scale, I would go with the Lyman Autoscale. It is inexpensive, and is great for working with sitck powders (they dont meter well in a powder measure). The auto scale automatically meters out a perfectly weighed charge with a puch of a button. The autoscale costs as much as a standalone digital scale.
Hornady, and RCBS make good powder measures. However, I would go with the LEE perfect powder measure for twenty bucks. They work great, and cost a little.
Dies... Hornady, RCBS, and Redding make great dies. No matter what you do, order an extra decap pin/rod with your die sets, they do ocasionally break.
Case lube (you will need this when resizing) Go with imperial sizing die wax. This stuff works great and 1 $3.00 can will last you thousands of shells.
Trimmers. I would go with the basic Hornady trimmer, as it uses the shell holder from the press.
RCBS also makes a good one. RCBS and Hornady shell holders are interchangable. Get a deburring tool to go with this, I use a Lee deburring tool, which works great.
Primer tool, get a Lee auto prime, they are cheap (around 15 bucks) and they work great. I have two of them for each primer size.
Buy a universal powder funel, and a loading block to hold the shells.
I started with a progressive, but I quickly bought a single stage press for loading rifle rounds with stick powders. They both have there uses. I use the single stage more than the progressive.
For the M1 Garand: You cannot go wrong with IMR 4895, as this is the propellant that was predominately used for that gun. Also, it produce the correct pressure cruve for the gas system.
Bullets: I like the Sierra 168 BTHP matchking, or the 155 Hornady AMAX. The 168 AMAX is another possibility.
Bottom line, you will save a LOT of money, and learn a LOT from reloading. It is an addictive hobby!
