Thanks Castaway,
Will there be any limitations to a RCBS such as a Rock Chucker as far as length of caliber that can be reloaded with it?
The Rockchucker does have a hight limitation when dealing with long rounds such as the 416 Rigby, 505 Gibbs and the various 3-3 1/2" NE rounds. The advantage of the rockchucker is it uses a 1 1/4"-12 bushing threaded 7/8-14" internally so that you can use larger dia dies.
The only round I load on my rockchucker is 500 Jeffrey, as the dies have a 1-14" body, so require a press larger then the co-ax. I do have to finagle bullets into the seating die, but it isn't an issue.
I'm personally a huge fan of the Forester Co-ax. It is an expensive press, but it is much faster to change calibers for then the traditional screw in single stage press, and the shell holder jaws are also faster then a conventional shellholder.
I load 50-100 rounds a week on the co-ax, and have never felt that I need to get a progressive due to speed. If you load 500 rds a week, then sure, go with the progressive, but 500 a year, you'll spend more time converting from one caliber to another then you would loading on a single stage press. You can always upgrade in the future.
While RCBS has a good warranty, and reputation, I think to some degree their products are over-rated, and they certainly aren't top of the line. Redding and forester make much higher quality products, and the price isn't much more. On the other hand, I've found Lee products to be very servicable, and they make quality ammunition for a minimal cash outlay.
