.35 R Marlin and cast?

[bunny]

I have a surplus of Hard cast .35 205 grain gas check bullets, rather than shoot them of in my .35 whelens or my .358's I figure this is a good reason to pick up a .35r Marlin 336. Any input on how these Marlins with micro groove barrels shoot with cast bullets?

I'm hearing on Marlin forum that most size at 359" and they shoot fine. A smaller diameter may (?) not be accurate in a MG barrel. I have only shot jacketed in my 35Rem (MG) and 356Win (Ballard) to date.
