Some ammunition makers are now making 45 ACP cases with Small primers. This would include any ammo with lead-free primers, and as reported by customers - Federal, Blazer, Speer and some Winchester cases.
Please be sure to check and sort your brass before reloading.
There is no impact on the load data when using a small primer vs. a large one. It is safe to use the data published for large primers for use with small primers.
