Go out and buy yourself a reloading manual. I like Noslers #5. It is quite universal in data, and is also informative and entertaining. Depending on what your shooting at, the 130 grain Partition or similar bullet will probably suit you well. You don't need to shoot a 150 grain bullet, even for elk. Just make sure you put a premium bullet in the right place, and that animal is dead on his feet. Most people don't know that the 150 grain bullet was originaly made for the .270 back when because hunters of the day were complaining the 130's were causing too much meat damage. That's when Winchester brought out the 150's. Naturally the heavier bullets with better controlled expansion were a hit for hunting larger game, but now-a-days, with premium controlled expansion bullets of superior design, you can do this with a lighter bullet. That means a flatter shot, less recoil, and more confidence with less flinching. Good hunting.
