300ultramag, the reason you probably couldn't find anything is because it Bansner's Ultimate Rifles and not Banser. A friend of mine just had a 300 wsm built by him and it is a really nice rifle. He primarily deals with custom made synthetic stocks and I'm almost positive he uses Howa actions. Of couse the actions are completely rebuilt. All the barrells are made by hand and can come almost any way you want. The rifle my friend has is super light and accurate especially with the floating barrell and overall a really nice gun. It's funny because PCN just had a special on Bansner's rifles last week that I was watching. It's amazing what goes into building one of those from scratch. Here's the url you were looking for.
