I had a similar problem with those bottles. I got the caps on, but it took lots of work and a little extra leverage, plus some bent caps. Some of them didn't look too great on the bottles, but they held up fine. Since then, I've given up on those bottles and am now bottling in 22 oz. bottles. Too bad, since some of those Polish beers are good and I like to reuse whenever possible.
