If you're going to shoot a caliber like the 416 Taylor you should learn to reload. Look for some used equipment. I'd suggest RCBS equipment since their customer service is great. If you ever need a part for one of their products just call them and they will send it free or charge. I'd look for RCBS Rockchucker press, scale and powder measures to start. Start right here with a WTB post. A good reloading manual would be one of the first things to buy.
Shipping will be expensive for the press so look locally. If you have any gun auctions in your area, check them out since they often have reloading stuff for sale as well. There are loads of info. available online from powder and bullet manufactures as well.
Good luck. You picked a great cartridge to get started.
