In about the late '80's I had a Winchester 100 in 284. I sort of wish I had not let that go, but it threw brass and I got tired of looking for the sort of expensive brass. Handy little rifle with a punch. If a guy were a factory ammo only guy, that would be one good way to go, in my opinion. However, besides the brass, the trigger took some getting used too.
I'm sort of heavy on the 7mm's now and prefer bolt or slide actions in my 7mm's. If I were to make up a 284, I think I'd buy a 'surprise' 700 and re-barrel it. I'd avoid a controlled feed action as I think there would be some feeding issues that would have to be done to feed those fat cartridges. But maybe if one were to buy a short fat cartridge rifle in a controlled feed version the re-barrel would be easy.
I have an Interarms Mk X in 6-284 that someone put together. I acquired it in a swap about 12 years ago, and it's a good shooter. I don't know what---if anything---was done to the feed rails but it has never given me any feeding problems. I can only get three or four rounds in the magazine, though.
