200 20x loads for 300 WM

[Dennis McAfee]

Looking for some starting load data for a 300 WM using the Berger 200 20x Bullet. Any suggestions will be appreciated.

H1000 or RL25 will get you where you want to be... My favorite powders in the winnie

RL-25 is always accurate and so is H-4831. RL-26 will get you decent speed and great accuracy, but is temperamental in the heat.
IMR-7828 is great all around. Good accuracy and speed.

Let us know what powders you want to work, cause there is so many good ones.

RL-25 you can start around 73 gr.
H-1000 start at 74 gr.
H-4831 start at 69 gr.
IMR-7828 start at 70 gr.
RL-26 start at 73 gr.
RL-23 start at 70 gr.

Retumbo is also a good powder with good speed and accuracy... but might be a tad to slow for the 200.20x. I don't mind compressed loads, but Retumbo seems to spike in pressure rather abnormally when heavily compressed.
