197 grain. Factory pointed.
Be really sweet to own a 7mm right now.
-
holy snap! I like that.
Suppose sierra beats Berger to a 155gr 6.5mm?
-
I dunno I hope they do, but I'd like to see one from anyone right now.
Seems like we're living in the golden age for LR shooting ATM.
-
Looks like a good candidate for the 7LRM!
-
1 in 7.5" or faster twist .
-
I bet an 8twist will spin them
-
8 twist in a 7-08 might not...but with at 2,800 fps (or thereabouts) in the LRM I bet an 8 twist will do just fine.
-
@dddoo7 I would concur
-
I was gonna ask who makes a 7.5twist 284.....
The 195 Berger needs 8.4 to stabilize if I remember right. I can't imagine two extra grains makes it that much longer that 8 won't do it.
Of course I can't shoot well enough to exploit it at long range.
-
Length is 1.713 according to their picture.
So running that through Berger's stability calculator at whatever atmospherics are standard and 2650 FPS it has a stability of 1.42 and you lose 2% BC to .761 g1
They're optimal for that length and weight is 1-7.75
