My experience with Mono metal bullets has been mixed. When they first arrived on the shooting scene, I had to try them because they were touted as the perfect bullet. Each time another one came out I had to try them. As far as accuracy goes, some were very accurate and some were not.
Some fouled badly because of the alloy chosen and others did not. The mono metal bullets that performed (Good accuracy And little fouling) did have one thing that I could never figure out and that was expansion consistency. Some expanded and looked great, at other times the did not and the game had to be tracked for some distance.
All the shots that I evaluated were traditional behind the shoulder shots so they were apples to apples results. I realize that sometimes a deer or Elk can do the impossible and run even though it is a perfect shot, so this was taken in account.
The jacketed bullets have done nearly the same at times, so the answer seemed to be the bullet selection was not the best for the shot and game that caused a less than perfect results.
In theory, the mono metal bullets should out perform the jacketed bullets but with so many variances in barrels, loads, velocities, distances, ETC the results will vary. As with any bullet, quality, design and materials are the key, but the use and placement is the other half on the equation.
My personal use of mono metal bullets is limited by the rifle and its performance on certain game, So I use the best performer for that rifle and don't get hung up on one type of bullet Because I haven't found that GOLDEN BULLET that will do everything.
Some good friends tell me that Hammer bullets have it figured out. They will be the next on my list to try. But that will be several hunting seasons because One shot doesn't trend and I like 6 to 10 examples before I render judgment on anything.
