Does anyone know the twist rate of the Model 7?
My No1 with a 1-14 will shoot a 55 gr flat base but not a 55 BT. Or maybe it will but I just have not found the recipe yet. My friends dad was the original owner and he worked up a ton of loads. Eventually he just stuck to the 55 gr FB. It shoots lighter gr factory ammo well.
50 gr Barnes seems to be right on the edge I feel. But it is also a 26” barrel so the velo is pretty high. Still not great but 1.25” at 100y. Good enough to try work up a load for that bullet.
