340 Weatherby and N570

[werth338]

Has anyone used N570 for 340 Weatherby or have quick load data for 225 or 250 grain bullets?

Sorry, but I have never used N570. I use R-19 (87.0 grains behind a Barnes 225 TTSX) Not much help, sorry

N570 is way to slow for 340 Wby. I have had best luck with R19, N160, R17 and MagPro. Never shot 300s so a little slower powder might work there too.

I wasn't sure given lack of data on it when looking at websites. I know 338 Lapua has a little more case capacity but with free not and able to run 340 a little harder if N570 would work. I know it works well in 338 Lapua.
