Has anyone had problems with H1000 at cold temps? Worked up loads at approx. 70 deg for 7mm RM and 300WM. Both at near max charge. Some friends took these loads hunting at approx. 10 to 15 deg. and reported what seemed to be extream low pressure (low recoil, somewhat quite, smoke).
I've disassembled many of the same batch and have found consistant charges and no other appearent defects. I plan to fire some of same batch this weekend at our current temps (+/- 30 deg). I am thinking about freezing some of the ammo to approx 10 deg and test firing. Does anyone think freezing ammo to 10 deg and firing in a rifle that is 30 deg will be a problem?
7mm RM
Win Large Mag Primer
H1000 Powder 69.4 gr
140 gr Game King
300 WM
Win Large Mag Primer
H1000 Powder 83.8 gr
165 gr BT
