Martini Hornet

Tiratore, thanks for the dm,I think you should post that information in the thread to give everyone the bigger picture.
When trying to assist information is the key to getting good responses.

Ignition can cause vertical, ie weak firing pin spring.

But before replacing the spring, I would stop using the graphite in the necks and lightly crimp the bullet in place. Many found that crimping the bullet improved consistency.

What are the readings from your Garmin?

Did the groups change when the barrel was replaced?

Btw that’s a nice looking Martini.
