I'm going to say no problem since all 22lr bullets I'm aware of are lead or mostly so, even the plated ones.
I've shot thousands of plain ol' lead bullets in my 39s. The two brands that shoot the best in my Mountie are exposed lead. I rarely clean the bore and when I do leading is not an issue.
I have had leading in centerfire firearms. The cause was typically undersized bullets or (too) hard bullets pushed too slow or inadequate lubing. Two of those centerfires rifles have Microgroove barrels (30-30 and a 44 Rem Mag). Both would shoot lead bullets very well. The 30-30 w/ microgroove actually out shoots my 30-30 336CB with Ballard rifling. Even when I did get leading the shallow grooves made clean-up easy.
