I have 2 Stainless fluted Sendero barrels, one is 7mm STW & the other is 300 Win Mag. I am going to have them converted into barrels for my TC Encore and the chambers re-cut by OTT (EDM process)into the same calibers or the 300 done into 30-8mm Rem Mag. Are the quality of these barrels worth the expense ($200) of the conversion? I paid about $150 each, so I won't have that much in them as compared to the TC offerings, also do these calibers work on the Remington 700 Long Action or is there a specific longer action used for the calibers based on the 375 H&H. Just exploring all my options.
