Re: Any Luck With Interbonds?
I also load right out to the lands by using guages such as the Stoney Point or special chamber guages made for each rifle. Custom barrels are always marked with a hack-saw cut on one end as they are shipped, and this end is always cut off. The cut-off piece can be made into an excellent O.L. guage if the smith simply chambers it identically to the rifle. I have these special guages for most of my custom built rifles.
Since that fitted ammo usually won't fit the magazine I cannot hunt with it so I decided to settle on 2.830" for my O.L.. I quit worrying about how far I am off the lands. Since doing that my accuracy has not changed much. No doubt much of that is because the rifles are very well built and have superb barrels.
I like to call the accuracy as it happens and could not honestly say that I can "average" 1/2'" groups with any of these rigs unless I have been shooting a lot and have my personal skills honed. I find 0.5" accuracy for five shots at 100 yards to be a very difficult standard to try for. Of course the 0.1's and 0.2's that happen are the ones I gloat about, never talk much about the 1.4's and 1.5's but they happen lots, particularly when testing factory ammo.
I have been shooting a lot of factory heavy barrel .308's that acquaintances are buying and we shoot the 2.830" OL through them with excellent accuracy. These are Win. Stealths and Rem. VS, VLS rifles and they all work very well with this OL.
I cannot tell you anything about the throats, just do not know anything about that.
