Not everywhere, sir - Arizona has no magazine limit for hunting.
Perhaps a forward "scout" type mount would be best?
The only SKS I had that was accurate was the Yugo. The most fun was the Norinco Paratrooper, also known as a Cowboy Companion. Sold that one for a song, dagnabbit.
Fun guns, but as military rifles they were obsolete when issued. They were excellent guerrilla rifles, idiot proof, and with a fixed mag, one less entry point for gunk or lost magazines.
I like the cartridge, been handloading for it for years, including cast bullets,
I must be doing something wrong, though - I can ring a 14" gong at 200 yards with irons off the bench, but I haven't really tried at 300 - can't SEE a target that size that far away with irons.
