Hello to all

I am new on the forum and wanted to say hello. I am trying to read a lot on here so any question I have wont be a "beating a dead horse" question to bring up past threads. I have had mostly handguns since moving to Calif back in the 70's when i was 6 but had a beautiful Winchester 30-30 back in Maine that me grandfather kept when we left. I just today purchased a Marlin 1895SBL 45-70 guide gun that I cant wait to shoot . Im going to be spending time in Idaho and Alaska so I wanted a rifle that would take dawn a T-Rex if needed. All I need now is a good scope for it. Any suggestions from others that have this rifle?

Thanks in advance for answering any off the wall questions I may have. I will be asking a lot of reloading questions in the near future (will make sure Im in the correct forum when I do)

Tim
