30 Gibbs data. I consider this to be very warm. Most of these loads are too hot (2+ grains above what I load) in my looooong throated Ruger #1 rechamber.
Currently, I'm loading 62.o gr IMR-4350 and the 150 gr TTSX for 3,100 fps in a 26" bbl. I consider that max in this rifle.
The old adage "start 10% below and work up" definately applies with this data.
