Hornady 180 sst data??

[hawk-i]

Hey guys,
My Hornady reloading manual is an older one and it doesn't have load data for 300 win mag with 180 gr. sst's and Reloader 22 powders. If someone would be so kind as to give me COAL and start and max load for the above it would be much appreciated. Thanks

From the 7th edition Hornady manual, 180gr bullet, RL-22 powder, Winchester brass, Winchester LRM primer:

Start - 63.5gr
Max load - 76.0gr

SAAMI maximum OAL is 3.34", but I would load to your rifle's throat length or maximum magazine length, whichever is shorter.

Thanks Mark!
I was playing with it yesterday and shot loads up to 77 grains and was thinking it was getting a little high at that (felt like there was a very slight increase of resistance when opening the bolt) but no pressure signs on the brass that I could see. Anyways my best group was a 75.5 grains...
Thanks again much appreciated!
