I doubt you'll find one. I searched for one a while back and they were all horrible... and I had a sound library as well. Eventually I payed about $15 for a set of explosions which I now remaster for whatever I need.
Good explosion sounds are as rare as hen's teeth. I say: ignore the free ones and pay a little.
