[QUOTE="Doozy, post: 1945683, member: 102153"] Disclaimer, I have only bedded one rifle, but I did a lot of research and found great writeups on this site. I have no doubt that Devcon steel (10110) is great. But their own published specs show that their aluminum putty is better (and better than titanium in I believe all but one attribute). The moral of the story is to do some research. Attributes to look for are high hardness, low shrinkage, high resistance to temperature changes, ability to perform in temperature extremes, and a slow and low-temperature cure (it won't matter if shrinkage is low if it super-heats while curing; the heat will cause the surrounding material to expand, then inevitably shrink.) One of the popular ones had issues with rusting! (I want to say Pro Bed 2000, but I can't remember; again here's a plug to search the history of this site because there is such good info from some of our resident experts). After researching, I came to the conclusion that Brownells Steel Bed was best. It's hard to know for sure because they don't do as well publishing their specs as Devcon. But I remembered my decision coming down to Devcon Aluminum or the Steel Bed. Although I didn't know the Steel Bed's resistance to temperature swings (in the atmosphere), I figured the Steel Bed was a safe bet since it has a ridiculously high concentration of stainless steel, and stainless steel if far less susceptible to temperature than aluminum. The one tip I can say from experience is don't bother with the dyes that come with the Steel Bed. I'm not convinced they do a thing but adulterate the proportions of putty and hardener. [/QUOTE]
