I want to put together a L61r sako in 300 weatherby, need braked , previously used or new sako Barrel , or sako barreled action.. like i have this Stock . Was it ever offered in 300 weatherby as its longer than 7mm mag etc . Or was a different action reserved for those ! And will a weatherby barrel work.... ?700 rem barrels look the same to me also ? ... but are they i hear they are Recoil lugged Differently ! I know they may all work with machine work ,Barrel facing and rechambering a few .000's to regain depth and restore headspacing .... But in actuality i want to find great parts make it my own Cheaper than the $1,500 usually wanted .. i'm not afraid to do the Stock work .. but Yikes am i patient enough to Get it done even at 96 % inlet ! Hope this makes sense I'm not good at proof reading !!!!
