300 Weatherby build for long range

[HvyMtlJzs]

Grandfather passed his Elk gun down to me and instead of just letting it sit in the safe and not be used I decided to put a build together and use the damned thing. Rifle is currently at the smith and will be getting a 28" finished length Schneider heavy varmint barrel with a salmon river solution brake. It'll be set in a Bell and Carlson stock along with a Timney trigger. The plan is to run 230gr A-Tips. So far my list of powders to test are Retumbo, H-1000 and the good ole 4831sc. Any input you boys can offer that have loaded with heavy bullets is appreciated. Im not looking for load data but more along the lines of personal experience with the cartridge with long VLD bullets.

Thanks in advance!

No recommendations from me, but any photos you could share? Sounds like an interesting project!

Any suggestions will need to be based on the chamber and the way it's cut.

SAAMI OAL is listed as 3.560". With your bullet seated at that length there is 1.024" of your bullet seated in this case.

Might want to decide some dimensions on your chamber first.

Standard bore is getting cut since weatherbys have a ton of free bore already. I have already resigned myself to the fact that it may be a single fed rifle and thats OK with me.

I personally feel the 300 WBY. would be a better performer with bullets weighing in the 190 to 200 gr class.

I have an Alamo Precision custom in .300 Weatherby and it hammers with 200 grain Nosler Accubonds @ 3075 fps!

I can't compare SAAMI chambers to my own 300Bee, I don't run .376" freebore, my rifle runs .500" freebore, in fact, my 340 and 375 all run the same. My 6.5-300Bee runs .376" over the standard SAAMI throat.
I have run 230's, but, velocity just wasn't pushing it fast enough and accuracy was waining beyond 400. I prefer less than MoA for such distances.
The 210g ABLR and 215g Berger EH faired much better for me, as did the 200g Accubond.

Cheers.

Hornady says their A-tip will shoot well regardless of seating depth and relationship to the rifling. ("bullets are forgiving of twist rate, seating depth and muzzle velocity.") Before you do make your heirloom into a single shot, try seating that A-tip to fit and feed from the magazine and work up a load.

An alternative that I know will work regardless of distance to the lands is a Berger Hybrid bullet. If the A-max fails to please, the 215, newer 217 or even the 230 would be a good choice.

As for powder choice, try Retumbo. It will yield high velocity, fill the case and is an extreme powder.

Thank you for the input. The smith said if we need to we can go back in and add a bit of free bore if we need to after the fact.

That was exactly my plan. I am not married to the A-tip and if it doesn't end up working try the Bergers. Retumbo is my first choice as well.

FWIW, last fall I shot a 752 lbs moose, 36" spread in Maine. The guide called him in to 40 yards, he stuck his head out low between two trees almost head on. I shot him right behind the jaw and he dropped! 30-06, 180 Nosler Accubond, the butcher found the bullet in the ham, went at least 5 feet of moose! I'm a big fan of Accubonds!

Just to show you the length!

Only load my 300 Wby with Nosler 150 Gr and let the velocity and bullet do its job like it has over the years- love it with the 150Gr!!!!
