Identify the START of the bend. Identify the END of the bend - and mark. These are the 'anvil points'. Press at the centre of the area. Do NOT do ANYTHING outside this area because it ain't damaged there! MANY more pages and much more than that of course but that's a start
After it's straightened, I would stress relieve the barrel....
