300 WM Expert

Are there any folks out there who are known to be 300 WM experts. By expert I mean they have extensive experience with the cartridge.

I'd like to talk to someone about the rifle that I'm looking to build.

Thanks

Tom

Re: 300 WM Expert

Expert in what field. Expert shooter? Expert gunsmith? Expert hanloader? Expert ballistician?
Or just a general purpose know-it-all? What's the question?

As one of his armorers once said of Carlos Hathcock " He doesn't know much about guns but he knows how to shoot."

300 Winchester Magnum

Reloader, ballastician, general.

What I'm after is setting the throat length properly for the configuration that I'm trying build.

I'd like to talk to someone on the phone so I explain what I'm after.

Re: 300 WM Expert

I worked up some dummy loads. The bullet is a Nosler Accubond 180gr.

The longer bullet is the theoretical maximum length. Essentially .308" buried in the case.

The shorter bullet is the theoretical minimum length. It's loaded to fit a standard long action magazine well of 3.40 and is loaded to a max length of 3.385.


Both bullets have the ogive marked. If both bullets were placed on a flat level surface the distance between the two ogive marks is the amount of throat play I have to work with.

I attached some pictures so folks could see what I'm talking about.

Anyone care to provide a reasoning as to where I should set the OAL with respect to ogive?

Thanks

Tom

Re: 300 WM Expert

What would your COAL be with the boattail of the bullet set at the neck/ shoulder junction, and will that length still work in your magbox ?
If it does, that is where I would set the ogive at.
I shoot the 190gr Bergers out of my 300WM, so cant help you with the AB
