I use an old(er) designed Rockchucker press, same one for the past 29 years. It handles my 300 RUM and 300 WBY just fine.
If the newer ones are even bigger - all the better.
You have bigger things to think about. Start at the Sinclar web site - order one of their catalogs, take a careful look at the case prep goodies.
If you are thinking about a 416 Rigby or 378 WBY based wildcat in the future, taking a look at one of the larger presses may not be a bad idea. However, the long stroke of that press when only loading a 308 based short cartridge will wear you out. I recently went to Wyoming for a PD shoot, it required 1800 rds for 2 shooters. The thought of running that many rds thru a x-large press makes my arm hurt just thinking about it.
