The difference isn't great, for sure, JB. I can't load to pressures that would allow my 25-308 to match the Bob because my Rem 788's rear lugs allow for too much action stretch if I lean on the powder measure. I can get 3400 fps from a 75-gr -- 3450 if I don't care about case life. That's a good 100-150 fps behind even standard-pressure Roberts loads. I load heavier bullets to regular 250 Savage speeds, because that's plenty and the lower pressure babies my rifle.
I had the chamber neck cut so I can form 25-308 directly from Winchester 308 or Rem 7-08 cases just by sizing. And now there are 260s (which came about after I'd built my 25-308). So brass is abundant no matter how we look at it.
'Sides, anybody can have a Roberts. I'm the only kid on my block to have a 25-308!
