I bought a 1914 Model 8 in .30 Remington a month ago. I checked the web for ammo, brass, and dies, then ordered it. I love that freakin' rifle.
Unfortunately, not one of the vendors actually had any brass in stock, and Remington says it might be a year before they run any more. Nothing else has a base diameter close to the .25-.30-.32 cartridges, other than various rimmed cartridges. Some of the guys on the "greatmodel8" forum have been de-rimming and cutting extractor grooves in .30-30 Winchester brass, but it seems there has been a run on that, too, other than a few people who think range pick-up brass is worth a fortune. Sorry, I'll just wait it out...
Meanwhile, I need to make a wrench for the barrel nut and shroud nut so I can take it apart.
FN and Remington made the 1900, Model 8, and Model 81 across 40 years, but I'd never even heard of one until the other day.
