Does anyone have experence with these? I have some to try in my 22-250 they are 60 grain & a fellow gave me a box to try. He says he has about 500 of them and doesn't use them and if they work for me I can have them. I use IMR 4064 in my 250s and have for a lot of years, so that is what I will try first.

Thanks ahead of time for any help.
