Any one have any good load date for the 300 Wby they would like to share?

Here's a link to reloadersnest.com. Select your bullet or powder and see the loads.
Dating back to 1944, it's still an amazing cartridge.

Dan:
As an old time reloader, I would like to suggest that you aquire one or possibly two good reloading manuals and study the loads in them and start with a suggested starting load and work up until you start to see pressure signs and then back off. The 300 WBY is a powerful cartridge and many rifles are chambered for this cartridge both by Weatherby and many others in the many years this cartridge has been on the market and each rifle is chambered differently. Weatherby designed his rifles with a lot of freebore and another 'smith may not have chambered his that way. With the pressure this cartridge generates, I would be reluctant to share loading data between two different rifles. Please don't take offense for stating my opinion since no offense was intended, only helpful advice. :)

Handloading is, of course, about custom making loads for your own gun. The biggest help one can be is to suggest powder/bullet weight combinations that work but the load then has to be fine tuned to your needs. Taking a load someone, including me, finds wonderful in one gun may not be wonderful in another.

In my opinion, the Nosler manual is the best one for suggesting powders likely to work well.

Yup...


Is this for punching holes in paper or getting some grub?

My WBY 300 loves RE22 and I used Partitions for years with excellent results. Here in California, I have had to use Barnes Triple X in certain places and this bullet is pretty impressive to say the least. I must admit I am partial to the Partitions since I have much more experience with them but the Barnes bullet is amazing.

Like LoadedRound I too am reluctant to share data that I worked up in my rifle for other .300 Weatherby chambered rifles.
I will add also that other manufacturers such Remington and Federal make cartridges for .300 Weatherby and can tell you from experience that loads worked up to near maximum or maximum in Weatherby brass WILL be overpressure in Remington brass. Factory Weatherby brass must have a little more internal volume than Remington brass because I find that with RP brass you should back off the powder charge about 1 1/2 grains when switching from factory brass. Don't know about other manufacturers, just Remington and Weatherby in my rifle. The RP brass is good quality though and I recommend it but work up loads for your RP brass or other brass and don't just use the same data for Weatherby brass.
Powders often recommended are IMR 4831, IMR 7828, Reloder 22, and Norma MRP which is very similiar to RL22. Almost all sources recommend using Federal 215 LR Magnum primer.
I also highly recommend getting a gauge to measure the shoulder push-back when sizing your brass. If you full-length resize the belted magnum case, at least with my dies and rifle, you'll only safely get 3-4 loadings before the case is stretched to the point of separating. A case gauge would allow you to adjust your sizing die to only barely push the shoulder back. The belted magnum case needs to be headspaced off the shoulder and not just the belt. The case will stretch just in front of the belt if you push the shoulder of the case back the full amount every sizing. Check the inside of your fired cases with the bent sharpened wire method and you can feel the circular ring depression stretch mark inside the case wall just in front of the belt. Hornady's Lock-n-Load headspace gauge set will work for measuring the shoulders of the .300 Wea case.
