all things being what they are both rifles have there pluses. I think both will have 23" barrels, If its the older 700 Rem BDL, its a wonderful rifle, and if its last years or newer Rugar its also a great rifle. i would see which ones fits you better. Place the buttstock in the crook of your elbow and see where you finger rests- the second fold of your trigger finger should be on the trigger but it can be adjusted since both guns will have a thick recoil pad.
Off the top of my head the 7mmUM throws a 150gr bullet about rought 3500fp of muzzel energy and the 300Winmag about about 4000fp with a similar weight. The advantage goes to the 300 in choice of bullet weights. To be honest both are a bit of an over kill for deer and the average black bear but if you can get one at a good price I might take the 7mm for lesser recoil. I have only shot the 300win mag 3 times and it kicks like a mule.
thanks I heard the 300 win is a beast. I am leaning towards a 7mm because it fits me better not that heavy and good range.
someone ask about bear meat, its not bad real greasy, very good in a a stew or soup dont think I could eat it by its self. Elk is very good a buddy of mine brought some back from a hunt, super lean and you can eat it rare which is good for m.e had me a good, about 14oz steak rare
I will let you know what I get and post a pic. soon I hope, I think I am going to buy one next week when I go to GA
