The 8x56R HungarianM95 cartridge uses .330 dia. bullets not .323. I had a really nice M95 carbine years ago but sold it because back then nobody made the correct size projectiles to reload it. Standard .323'' 8mm's would slide right down the bore. Remington 40X bore cleaner works wonders for cleaning badly fouled or slightly rusty bores. Be careful using overly strong chemical cleaners because they can actually do more harm than good, especailly in stainless steel barrels.
