Hornady soon to introduce another .375
You can read more about it here:
Might make an interesting round for newer double rifles, especially if the twist rate is fast enough to stabilize 350's. However, seems like most doubles are about tossing out big lead at slow velocities so not sure where it will fit in. Could be a nice option for the Ruger #1 as well.
Still, nice to see Hornady is busy with new products.
Interesting, not much real information but if I had to guess I would say it will be a flanged 375 Ruger. Since I know little to nothing about double rifles I can't comment on its use there. However, this could lead to some neat wildcat cartridges in revolvers and leverguns.
