I had heard that the Hornady Roo max now are Boat tail projectiles whereas they were flat base. Not that it really makes all the much difference. The new ones I have received are boat tail. So I'm interested in seeing if they shoot any better.
I had the idea that I would use up the Roo max that I had and the AR2207 that I don't really use. So I loaded a few up at the starting charge and was pretty happy with the initial results. Seems the Roo max like Ar2207?
I will do some testing and post up results. The Sierra super Roo do shoot well in both my 223. But feel the Hornady may be a bit more explosive and perform abit better in some situations. Will try test that at also.
