I want to develop a load for caribou hunting for 243 Winchester using either the Barnes 80 grn TTSX or 85 grain TSX, but I want to use 4895 powder, and I haven't found 4895 data for those bullets. Does anyone know or have any experience along these lines? (Or does anyone know of a printed manual containing such?)
I want to use 4895 because I had good results with it in this rife with Sierra 60 and 90 grn bullets (yearrrrs ago). It works well in my M1, and I have a bunch of it. (Of course, if it doesn't work, it doesn't work.)
Also. I'll be testing loads in the winter, but I'll be sing them in the fall. In what ways will temperature and humidity affect accuracy and velocity?
