Even though I know the general consensus around here with respect to AWC, I can tell you my Thunertrap works like a champ on my 300RUM. I called ahead and got the GTG from AWC beforehand, but it sounds great and have had no ill effects. It is the 8" .30 cal version. Granted it is a bit heavier than Ti, but I have manageable, repeatable POI shift, and being SS, it comes in under $1K. Even though many here will respond negatively to this, I stand by my assessment. Granted, they have a reputation of late for less than stellar CS, and Chris can be a royal prick, but they have treated me well once we got past Chris' personality and the product is a good one.
That said, you can't beat my SRT Titanium Shadow LM made for the .338 Lapua Mag. I use it on my .300RUM as well as my Lapua and it is exceptionally quiet, very lightweight, and has little to no noticeable POI shift. They will run you a little more than a grand, but damned well worth every penny. Doug is excellent to work with, and his customer service is the equal of anyone in the business. I have a number of his cans and ALL are as good or better than any other brands I own.
I would LOVE to own a Titan, but the price just isn't right when compared to my SRT. I have shot one at a gathering, and I do like it, but for my money the SRT is atop the heap. YMMV, so the best advice I can give you is go to a silencer shoot, or find folks willing to let you hear their cans BEFORE you buy and make an informed choice.
