RE: $300 budget to get started in reloading, Help?
Check Ebay, research prices for new items from sites like midwayusa or cabelas then go to ebay so that you have an idea of what is a good deal or not. Often you can pick up a kit for about half of new. To start on the cheap there is absolutely nothing wrong with Lee products. Most presses will handle magnum length cartridges I personally use a Lyman Tmag 2 turret press now but started out with a Lee autoindexing turret that I still use when loading pistol cartridges.
