The Short answer is "Yes". I might be assuming to much but if you don't already have one and are new to reloading, I'd not recommend as auto-press, they are way to complicated, will confuse your data stream, at a time when you need total concentration.
If this is the case get a descent "O" press and you'll have it forever. After you get your feet real wet with experience, you'll use the O-Press with the Dillon type, to compliment your Ballistic endeavors nicely.
I personally have two RCBS Rock-Chuckers and have had one for more than 40 years. I can't imagine, even with all the high-end reloading equipment, being without a good O-Press too.
Just for grins Lee makes a pretty good affordable O-Press too,there are others and don't be afraid to buy a used O-Press, you can't wear them out. Case in point.. I'd love to buy a wore-out RCBS press (I've seen them for $15 bucks with the die threads broken/stripped out), with RCBS customer service being as it is, they will rebuild or exchange it for new..
