What's the difference in RCBS single stage presses? I'm looking at getting a Rock Chucker. But I'm interested to to know what is different between the RC, RS, and JR. The roman numbers (e.i. RC IV) behind them I'm guessing are just newer versions. Any Info before I buy one would be appreciated.
You couldn't beat(not really there were better presses then too, they were just priced out of range of most human beings) it forty years ago, but you can easily beat it now.
The RC JR and the RS(first model) were basically the same press, I know this because I have one. They were made of cast iron and didn't have the best or strongest linkage around. They were and are still pretty good little presses. When they came out with the RS 3 it became an aluminium RC, for all intents and purposes.
As Sam says the Rockchucker is a solid press which will last a lifetime.
I have one but I also have a Lyman Turret press which I reckon does all that the Rockchucker does just as well and then some! (both are over 25 years old and both still going strong with no breakages so far.) (My Lyman turret handles up to 30-06 and 8mm no problems.)
I tend to use the Lyman much more than the rockchucker so I would tend to suggest if you are going to buy a Rockchucker you think about spending the extra $8 and buy the Lyman T-mag Turret instead, it is much more convenient.
If your mind is set on a RCBS Press, then definitely go for the Rockchucker Supreme, no point going for the lower models, you can't beat cubes
How can I 'Soar with the Eagles' when I'm working with such 'Turkeys'!
I bought something called a Partner Press - not sure if this is a US press under a different brand name for Australia - and so far have no real issues with it (hasn't been all that long using it, mind you, but am happy). The one problem I DID have - the primer arm not putting the bloody primers into the cases properly - I traced to the cases (S&B .303 British - some may swear by them; I'll swear at them).
I'll tell you in forty years whether it's still working. I don't intend to give it away anytime soon.
