[QUOTE="Kevin Thomas, post: 620977, member: 15748"] The very same. Mid chambered up my personal Palma gun, too, and I followed his recommendations for setting up the Palma test barrels. Undersize dimensions (.2985" bores, .3065" grooves, if memory serves) 1x13" and finished off at about 30". Essentially the same thing the US Palma team shooters were using. I want to say the reamer was a PTG, but it was specifically what he suggested. The throat's substantially shorter and has a shallower leade angle that matched up with the 155s seated at 2.800" OAL. I ran across the Obermeyer chamber many years back, and tried it in a couple test guns. Had consistently excellent results, so that just became the "default" go-to reamer when I was setting up new 308 test barrels. I think I got these reamers through PTG as well, but the profile (hence the name) was done to Boots' original specs. Again, different leade angle played into that one, and man did they shoot well! Just for clarification to others who may read this thread, no, we never used anything that would be considered a tight neck chamber, or a true BR design. Far too much shooting and far too little time to mess with such nonsense in a lab environment. [/QUOTE]
