Hello eveyone, Im new to the forum here. I have finally decided to build a custom long range hunting rifle and cant really decide on the best caliber. This rifle will be used for elk, muleys, kudu, and at least once on an eland (if the good Lord is willing). I have some what narrowed my list down to the .300 Win Mag and the 7mm Allen Mag. I am 5'10" and 160 lbs so I am concerned with recoil. The rifle should not exceed 9 lbs and 26" barrel so as to make it more friendly on my mountain hunts. My Kimber .325 WSM has a sharp recoil but I can manage it well (I think I can shoot better than this particular rifle!) The 7mm AM should be sufficient on the large eland with 175 grainers out to 500+ I would think, certainly adequate for the other large critters. I like the .300 for 200 and 220 grainer capability but my all purpose load wiould be the 180 grainer. SO..., is there any other calibers that you would recommend? Thoughts, comments, suggestion? HELP! Thanks in advance.
