It could be a twin to mine. Once put an Ernie's the Gunsmith spring in it, the rifle started shooting tiny groups with my best handloads at commercial ammo speeds.
You are one smart man. The other poster that said he bought a Timney for his, wasted a chit ton of money. The Ernie spring is the only way to go for the MOA. I also used to have a 2008 limited edition, but it was a 300 WSM. I found it at a local gunshow for $600.00. It only had a box of ammo though it too. Damn near new..:
