Don't waste your money! They are not a spitzer but more suited to a 22 Hornet not a 22/250. They are more of a semi spitzer just one step up from a round nose.
I beg to disagree. I use 45gn, 46gn, 50gn and 55gn bullets in my 22-250 and all shoot 0.5MOA or less (depending on how good I am that day) at 100yds. I'm on my last 500 of 10,000 that I bought in the spring of '04.
