[QUOTE="Salmonhead, post: 2819653, member: 117979"] Assuming the components are sound, and since both the 4350 and h1000 were slow, Im going with a shot out barrel. I have an older m70 winchester thats notoriously slow. It is about gone. I have a fresh tikka that routinely prints 70 to 100 fps slower than a 1980 built m700. Some of it is just the barrel, some could be the throat is getting highly eroded and you're loosing pressure as a result. I also have an old article by Finn Aagard where his particular rifle took 3 grains more powder to match the stated velocities. He also had a few thousand rounds down the barrel. I would either step on the loads to see if velocity comes up without pressure, or chalk it up to a bad barrel and move on. [/QUOTE]
