I have yet to chrono my 15" non-braked '06 just wondering if any of you guys have ? I'm using a 150gr Hornady with 58grs of IMR4350.I have been thinking of sending my '06 to SSK to have it rechambered to an '06jdj but, I'm not sure it would give me that much more velocity.My '06 is shooting real good now and I am scared to mess with it.
