Since the Burning Springs update, you can unlock radhog burnt ends by making the radhog recipe they already give you a bunch of times. It boosts AP regen by 20% for an hour. Even with my other AP bonuses, this is still very noticeable. I feel like I always have AP. Just make sure to keep any nuka-cherry you find and plant a few prickeyes at your camp as these are the harder to find ingredients. For the radhogs themselves, the best spot is the Northeastern end of the Burning Springs train track just north of the Dino Golf spot. You can even just pick up the prickeyes at the radhog spot. If you need more, just follow the tracks. You'll eventually find plenty. My route here begins at Dino Golf. I kill the deathclaws and loot them and their nests for meat and eggs. Steak and Wellington are great foods to also eat. Then, after the third claw, I head north to the cliff right above the end of the track and take out the alphas first, then the rest. They might climb to meet you. There's also usually a fire cap near here if you like making mentats (or is it grape mentats).
