I recently rebarreled a Rem SA to .308 Win. I used a "famous maker" SS match, hand-lapped barrel in about a #2 (light sporter)contour. I chambered with a new PTG reamer. The first few outings, the grouping was a disapointing 1 1/2 - 2" groups. Both factory and hand loads were used. I recrowned the barrel with minor improvement. So, I visited with the manufacturer - literally! I took the rifle, targets, reamer, and some fired cases to the shop.
After some inspection, they offered a few improvements that would likely help things. A small correction to the bedding and making the mag box slightly loose (to prevent any stress), and lug lapping (can't believe I had neglected that) were the major ones. After these tasks were completed, accuracy has improved - down to an inch, now. But I think it will do better.
I wish to shoot 150 gr bullets, But, no matter what the weight, the mag box limits length (2.815") to the point I am near 0.100" off the lands. Not only does that stuff a lot of bullet into the case (hence the 150s), but it leaves me with a hell of a bullet jump - minimum 0.090". I can't, for the time being, spring for an extended mag, like a Wyatt's. I don't have the knowledge, ability, or tooling needed.
My first thought is to send the reamer back to Dave, and let him re-cut it for my OAL. That would be a simple fix. Set it back and rechamber - problem solved. Or is it? So many of you guys have BTDT, that I thought I'd ask for opinions/input before doing this. Is there anything I'm missing? Of course, there'd be a need for a new reamer, if I ever wanted a longer oal; or at least a throater. That's the only drawback I can see. Am I thinking this thru - clearly? Thanks for your time...................................Bug.
