My pup loves to chew things, and eventually we found out that she likes chewing on elk and ram horns. If you're in a fairly rural area, a lot of places carry them, and if not, Amazon might carry them. Here's an Amazon link to what my pup has, but if you have a smaller dog, I recommend a smaller chew.
I haven't read much on deer antlers so I can't speak to those but the elk antlers have been the best thing for my 8 month old beagle/lab. My 2 year old pit loves them too. No injuries. They don't chip, they get slightly pliable as they chew and then dissolve slowly over time. The only thing to be aware of is that eventually after weeks or months of chewing, they will get short and be a choking hazard. Here is where I buy mine.
Crap, should have clarified. ONLY for a puppy up to 16 weeks. The "serving" sizes are so small it would be easy for the dog to swallow the entire chew much past four months.
One we got from our local grocery store (Wegman's), the other was from a high-end pet food store and I'm not sure of the brand. The latter lasted a lot longer than the former.
Sounds like you too have a hardcore chewer. After trying just about everything, we settled on these: http://www.amazon.com/Elk-Antler-Dog-Chews-Satisfaction/dp/B00JYN1HGK/ref=sr_1_7?s=pet-supplies&ie=UTF8&qid=1435631860&sr=1-7
