Confidence votes 948. Generally, horses hooves grow about 1/2 or 12 cm in 4 to 6 weeks. The growth is slightly faster in warm wet environments and less in dry or cold environments. a horse can grow a complete new hoof in about a year.
And i know what Breed Bolt is!! lol I would say he's a White German Shepherd. He could also be a husky. Or any other white-pointy eared dog...but because I'm a GSD nut...I'll say hes a White Shepherd. i think hes white German Shepherd but i also dont think he is cause hes so small.
Update - emailed DSA directly - Received a response from Russ. 1  Both are true, The Bolt itself is not shot peened, but the carrier is shot peened, when most people refer to a bolt they generally mean a true complete bolt carrier group. This may be where the confusion lies, there really isn't any benefit to doing the process to the bolt only the carrier gets improved when the process is done.
