How to lengthen the throat of my rifle, can I do it myself?

[Brother_Love]

I have just got a new 243 rifle that I want to use to shoot cast bullets. The throat is extremely short with the rifling engaging the bullet about 1/4" from case mouth. This makes it extremely difficult or impossible to chamber a round unless the bullet is seated deep into the case.

I would like to have the throat opened up a little. Can I do this myself or should I find a gunsmith to do this? The rifle is a new Mossberg Patriot. It shoots and chambers great with factory ammo.

Thank you, BL

It is not hard to do,just take your time.

Check often and you should be good to go.
