Im settin on a fence with a spring rifle build project, and the more I investegate the old threads on this cal. the more intrested I am, so with that and Im sure mr.Kirby will give all his proffesional advice as will all eperianced owners of this canon. 1st Question what is the realistic barrel life of this round as a long range hunting outfit with regular barrel cleaning and not maxing the horsepower. 1000rds?? prolly shot 200 a year. 2nd whats a suffiecant barrel length and contour, this is not a walking rifle. (will be hauled around on a wheeler..lol). as in to some degree. weight not a problem prolly 19-21lbs? 3rd prolly be sticking to the off the shelf big wig manufactor bullets such as sierra's (300grner). whats twist is working..10? 4th I owned a 18lb 338 lapua imp (with brake)and recoil didnt bother me nor blast, so what can one expect for recoil? Is it that BAD?! 5th also didnt see alot of pics of a proportional bult rifles as in everything looks inproportionas in big barrel, big action and big stock im a looks guy and was lookn at Mcmilons MCHALE stock seemed to be bigger everywere. does anyone shoot with this stock. 5th well im sure ill think of something!!! Also the 338 AM is a thought being Kirby has preformed brass GO BIG OR GO HOME RIGHT??
