I'm looking for loading data for 55gr. bullets and Varget or other powders that you 225 shooters are using.
I have been using 4064 which I am out of and I have Varget on hand.

Data from Hodgon Powder.com

Sorry does not include Varget. will check my manuals at home, No one has llikely developed any loads for the .225 since Varget was introduced. You may be able to use starting loads for the 22-250 .

Cartridge: 225 Winchester
Load Type: Rifle

Varget is only a bit slower on hodgdon's burn rate chart, why not work up slowly with using 4064 starting data ?

I know in 22-250 they were so damn close.

For what its worth...I see two loads on reloader's nest using 33 and 33.3 gr. of varget which seems about max to me.
 
Varget being slower than 4064 will produce less pressure with equal charges under the same bullet. That being said, I would reduce your 4064 working load by a full grain of Varget then work up to the level that suits you, probably there will be a half a grain that separates Varget and 4064.
 
Thanks for the input.
Still have some rounds with 4064 to use and will be trying Varget this summer.
I plan on looking at the powders around varget on the burning rate chart and compare with the data that I have collected.
