The only rounds I've shot through it are reloads. My buddy has a Model 1895 Marlin and has been trying different loads for quite some time and has come up with one his gun likes, so I reloaded and shot those and my gun seems to like it. 300 gr. Sierra hp and 63 grs H335. This is nice since I happen to have about 12 pounds of the stuff. Load data is kind of confusing for the 45/70. It seems that most people say to use load data for the lever actions, but Sierra's book shows a maximum load of 63.6 of H335 while Hogdgon shows a maximum load for the Marlin lever action as 68 grs. of H335 and both books are using the same bullet. That's a big difference. I'd like to experiment a little with different loads, but at the same time I don't want to over stress the action. According to Hodgdon's book the 68 gr. load is still only at 38,800 CUP.
Hey Slavage, That's just a 1/4" Kick-Eez Cheek-Eez. I put it on there mainly to give me a little more comb height, but it has the bonus of absorbing shock.
