First batch all shoot off

[Linedog]

Thanks for all the help for my primer seating problems and neck seating issues ,both resolved . Loaded 20 rounds this morning of 243 , 5 each of 36,37,38,39 grn's of IMR 4064 , remington primers .3 shells didn't fire. Not sure if I set the primers too deep or what . The ones that didn't fire had a good indent in the primer so I am not sure what happened but boys is this ever fun . All hit the target and got decent groups , some better than others .
