So yes you can use them, but you can't buy new rimfire hi-caps in Cali.
Interesting... My friend had found a few 25-round 715T mags left by his roommate. Is he in violation by possessing them considering he didn't buy them? I know there was no such thing as a 715T back in 2000, let alone a 715T 25-round mag!
