Ive been running a load of Reloader 22 at i think 69.7 grains (dont have my book in front of me)behind a 180 grain accubond. was worked up on a 80 degree day at around 800ft alt . 3050fps out of a 24 inch barrel Well ill be moving across the country for a year so can i just load a bunch of these loads for my rifle and will i have any issues with the change in alt. and temp. Would like to use up the last of my 22 how was the older stuff about 3-4 years ago made I dont see many loads for the 300wsm using this any more ?
