OAL Question 300 wby mag

[JRWhit]

I'm in the process of working loads for a weatherby vanguard series 2, chambered 300 wby magnum. I was trying to figure my OAL and put a 180 gn soft point in an empty casing in order to chamber and see where the rifling starts so that I could figure desired OAL for my rifle. What I found is that the bullet comes no where near contact with the landings. I this due to the narrowness of the bullet or larger starting diameter of the barrel? I have some heavier grain round nose coming and am curious to see if they contact rifling at any depth. Is this a rifle more suited for heavy round nose or am I missing something?

The 300 Weatherby Magnum rifle has a long free bore. You will never be able to seat a bullet out that far and still feed through the magazine. Seat the bullet so it will feed through the magazine or seat to the channilure.

Too much freebore. Load to the length limits of the magazine.

Understood. I guess I'll be seating at factory length. New lesson learned, thanks.
