Enlarging Flash Hole

[Old Jim]

Klaus,

Sometimes we overthink things that are best left alone.

When flash-holes are made thru the case-bottom, a manufacturing-bur can be created inside the case, and it can be removed with a small tool. Removal of it may improve the flash created by the primer into the powder charge. So much has been said about using different types of primers, ie, pistol, LR and Magnum LR primers. Some experimenting with the different primers offered should indicate to the shooter acceptable performance in trial loads.
Primer-pockets should be checked for proper depth.

Hold center,

Jim
