What 2-Piper meant was that IMR 7625 just doesn't burn very well in colder temperatures. I shoot a lot of the stuff in the summer but when it comes bird season I switch to IMR PB, which seems to burn well down at least to temperatures that I'm wanting to head for the car--and the bar. For what it's worth, the 1894 is built hell for stout and you should have no concern about strength if the gun is in good condition.
