Good day ladies and gentleman,

Let's start a Recipe book for everyone to post their winning recipes in 300 WIN MAG/ WSM/ RUM/ ETC

First and foremost, there are a few things that need to happen here for this post to be successful.

1: We need to stick to a pre-established format.
2: We only post recipes. No congratulations, questions or any other posts than recipes.
3: Questions or congrats to posters about certain recipes to be directed via PM so it doesn't clutter the original post with things other than recipes.

One very important thing, a recipe that works in a firearm may not work in yours. When the recipe is HOT (close or above recommended amount of powder), work your way up to it. . This is serious stuff. It can cause catastrophic failure of your firearm or hurt you or someone. We are mostly all grown ups, let's use our heads if the recipe is hot. WORK UP TO IT.

Here's a format that seems to make sens.

Caliber:
Rifle brand:
Rifle Model:
Custom built:
Barrel length and twist:
Projectile brand, model and weight:
Powder brand and weight:
LOAD CONSIDERED HOT OR CLOSE TO MAX:
Primers:
Coal:
Ogive length:
Brass:
Brass length:
Distance to lands:

Results at 100, 200, 300 (whatever is available)

If available:
Velocity (average):
Outside temperature:
Wind and direction:
Barometric pressure and other relevant data:

Thank you very much everyone and let's make this a successful post for everyone that are getting into reloading a new caliber or are lost in the amount of options available in this caliber. This will also be awesome for anyone who's looking for a start point or simply improve their own recipe or try something else. It will also tremendously simplify the search and the amount of time spent on the search button option and the read through the hundreds of posts and irrelevant reading someone will have to go through in order to get a start point!

We all know that something that does wonders in someone's rifle may not work in someone else's rifle even if it is the exact same thing only a few different serial number away.

Once again, thank you everyone for your participation in this recipe and let's make it a go to for anyone who needs it.
