I echo the admonition to never use an over powder wad if you value your chamber. You should elevate your muzzle to orient the reduced powder charge back to the primer, then lower to sight plane, but do please keep your finger off the trigger until its pointed downrange.
Through the years of shooting thousands of reduced loads, both cast and jacketed, Ive come to rely on a couple of reload data sources. The Lyman Cast Bullet Handbook is my go-to volume. If you use the top listed loads for cast bullets, reduced by 10%, for jacketed bullets you will do fine. From those reloading manuals that list jacketed only you can use the starting load data with success, though it will perhaps make loads faster than you want. Its still a good place to start.
