let me start out with some background. I am not a 10 year old first time shooter. I have been hunting for that past 20 yrs, however I have always used a 30-30 or .270. I used these because I was only hunting whitetail in upstate NY. I dont have a lot of call for long range shots. I am planning to go hunting for Caribou this year and future big game hunts. I have done a lot of reading on good calibers for large big game and have determined either the .300 winMag or a 7mm Mag seem to be my options. I am sure there are many more but these are what I think would be best for my current whitetail hunting and still me me future big game ability. Please correct me on any of this if I am wrong. As for the rifle I was looking at the remington 700. I have been debating whether or not to go with a heavy barrel or not. I seem to shoot better with a rifle that has some weight to it. but I am unsure if the heavy barrel on a 700 would be too much. I have not had an opportunity to hold this gun so I am drawing from the internet and other opinions. Any thoughts and input would be great. if you need more info or have questions for me, please free to ask.
