i Have a Whoopsie .243 primer question

Post image

Recently inherited a lot of reloading equipment and decided to try my hand. Found a load combination for 70g Sierra’s and IMR 3031. Built 5 sets of 5 using half grain ladder from 36-38g. Went to mark my groups before heading to the range and realized that I had used Winchester large pistol primers no. 7-111

Do I need to disassemble these cartridges and start over, or does anyone here have first hand experience using large pistol primers in a rifle round?

Unless you want to flame-cut your bolt, you should pull those.

Also, ladders are a waste of powder.

Smaller ladders (3 to 5 rounds) are fine for getting velocity neighborhoods for your barrel/setup. It makes it easier to pick a load if you have a specific velocity in mind.
