I changed my hunting weapons. This year we are going to hunt with iron sighted levers. What is the effective range of the 38-55 shooting the 255sp? I also have a 348, 358, 45-70, 375win. Three of us are hunting cow elk and the other 2 guys will be using 45-70's. I would like to use something different. We are very excited to make this hunt challanging. The 38-55 has a tang sight and the others are standard or buckhorn. My concern is the power of the 38-55 vs the other cartridges. Any input from the pros here would be appreciated. We are hunting in Arizona and are use to using bolts with high power scopes. Rick
