I started with Re15 and the 225 gr. Barnes TSX. Found nirvana at 60.4 gr. and 2710 FPS. I never looked back.
FWIW, I just checked in three manuals for 4350 (either one) and 250 gr. bullets. Powder was conspicuous by it's absence. Just confirms that it and 4831 are too slow for the cartridge. As far as temperature sensitivity, my load was worked up at temps between 95 and 105 degrees F. Last elk I shot was at 4 degrees F above zero. Bullet hit the elk right where it was supposed to go. The elk died.
