I sold my 243 over the weekend and made a teenager who was saving money for his 1st rifle and his dad very happy . the dad was even more happy when I sold him all the brass dies and bullets I had for it along with the gun . ive got about 3/4 pound of imr 4831 here and the only gun I used it for was the 243 . the only other rifles I load for is 30 30 win and 35 rem and I usually use varget or pistol powders for them. does anyone have any data for this powder with either of those calibers? weather its just plinking lead bullet load or otherwise . I cant find any in my manuals or online and I hate to waist it with the powder situation the way it is today .if not i'll see if my father inlaw can use it for his 7mm08 I guess
