Wrong caliber, that was my downfall. But it was easily remedied by setting the barrel back and rechambering, I got lucky. szihn is right on the money in my opinion. Two of my most recent builds had me staying with the original design and weight of factory rifles I really like, but improving them with a caliber they didn't offer and the other one with a twist they didn't offer. The latter one I built an English walnut stock for also, but staying with the original stock specs and adding a check piece.
The weight and balance are very close to the factory's although mine may be under theirs by a few oz. Barrel length and contour match the factory's. These 2 are my idea of the perfect hunting rifle and to say I am satisfied would be an understatement.
