Judson, I have some problems with what your saying about ultralights. If a barrel is freefloated, I can see how it doesn' t climb as it heats up. But lets say a barrel is glass bedded all the way up to the end of the forearm, with not upward pressure, just laying perfectly against the metal of the barrel, how will it climb???? What physics or static pressure will cause this climb? I can see if you have the 10lbs of upward pressure. Why would you need more than a dollar bill. I know alot of people that glassbeds thier ultralights all the way up to the end. They do this because they love wood, but hate the warping when the barrel heats up and the wood swells, but in thier case, swelling is a moot point. I won' t do it on the two light guns I got cause I don' t want to cut out any of the wood on my medallion or mauser. Forearms are a little thin, so yes I freefloat. Just don' t understand your logic if you put in some proper pillars and bed properly. I never see these guns change POI as you are suggesting. All of my ultralights are very, very finicky. Yes, they all shoot less than a .75" with my handloads if I let cool 10 min between two shot strings, but changing weather, or COL very slightly has a huge impact. With these guns that are properly bedded, they seem more tolerant to changing loads since thier barrel whip goes down significantly with proper bedding.
