I have a pound of IMR 4895 and was thinking about using it to work up a hunting load for my .270 win.
I've heard that IMR 4895 is temperature sensitive in regards to pressures/velocity. Hodgdon shows a 166 fps spread between 0-125 degrees in a 22-250.
I'm more interested in how it would be in a .270 in temperatures from 30-95 degrees.
Most likely I would work up the load during the summer where it could be in the upper 80's to upper 90's, and then when Deer season rolls around temps are usually 30's-70's.
So, any idea whether a load that shoots accurately and is sighted in at 95 degrees will still be ok at 30 degrees?
Anybody have personal experience using IMR 4895 in these temps?
I know there is no substitute for hands on experience, but I'm trying to find out now whether I need to find another powder or whether this is suitable.
Thanks!
