I had more trouble getting velocity from the 160s and 175s. It might just be my barrel though. I have a 1 in 9 twisted bartlein sitting here for when it goes. I hope that the 5r rifling doesn't cause any problems. I'd like to talk to that cover guy sometime.
79: 160's and up is where 7mm magnums start to get stubborn,due to the fact they are heavy and more bearing surface. But mostly I've had little to no difficulty with 160-175's. My barrel is a Krieger. No problem with velocities of 3200-3250 with 160's,and 3050-3075 with 175's and H1000, RL25, etc.
If yours is a Rem 700 barrel I have noticed they tend to run on the slow side,although that's not universally true.Just a trend we noticed comparing my friends Rem 700's in different calibers to my Kriegers and M70's.
I think your Bartlein will be very good with no issues. Gene Simillion just got one in for my friend's Mashburn and is building another for a second friend, both on Bartlein barrels.
