Getting good ignition with straight cases is what led John Buhmiller to experiment with double primers, that is, one primer in the primer pocket, as normal, and another beneath the bullet. This works as I've tested it myself, and it allows a reduction in powder charge of around 5gr. for identical ballistics. It is not something to experiment with unless you are well healed in loading and understand completely what you are up to.

Any load development must start with low pressure loads and build from there - with exactly the same components all the way through the testing. Changing components willy/nilly is what blows guns up and injures shooters and bystanders.

Be careful out there.
