Welcome to the Ammo sub-forum !
Our Stickies are loaded with answers to frequently answered questions. For your convenience, we have divided ammo questions into 2 groups: handloaded and factory. So, you may find doing some reading
HERE to be very helpful.
The very last document in that directory may hold the answer to your question. If not, then please consider adding what you know to the community knowledge base for other users like yourself.
Go there first and if you still have questions, then by all means ask.
