Re: IMR 8208 XBR loads for 22-250
I don't have any yet but I do know that IMR4064 and varget have produced 1 hole groups in my 22-250.If you go to the IMR web site or call they may have some data or tell you what the burn rate is in comparison to other powders. I did find on the site that 36.6 gr with a 36 gr bullet is about 50,000 psi and a vel. around 4,100 fps
