Ed ScarboroLoad data for 30-378 Weatherby
I started working on a load for the 30-378 with 200gr TSX's about the time everything shut down for the pandemic. Now, I can't find any of the 200gr TSX's but I have found 208gr TTSX bullets. Does anyone have load data using either RL22 or RL25. I have plenty of those two powders and have used them in the past with the 180gr TSX's.

DavidReedYou need a 8.5” twist barrel to run the 208 gr. LRX. It’s 0.200” longer than the 200 gr. LRX which is already a long bullet.
The 190 gr. LRX may be a better alternative (assuming your .30-378 has 1-10” twist) and I’ve seen them on the shelf locally and some of the online vendors have had them lately.

Ed ScarboroI've ordered some 190's to try after looking at the twist rate for the 208's. Thanks for reminding me to look at the twist rate.
