OK I made some progress. The new AI can that will be good for any 30 cal over the AI Brake has gained some weight and is now 240 grams. It extends 3mm further aft over the brake and uses a second oring. It is double walled in the first section and other areas are thicker and reinforced for a VERY solid can. The 338 will be the same only scaled up a bit.
Next to design will be the brake mounted similar to the ones Chris pictured above and these will have a ratchet feature as well as another feature available for absolute security.
The A2 FH mount is printing now and will hopefully be a next to final design that is useful for serious testing. This unit required another 7 designs this month and was a lot harder than I expected to get all the features I wanted to work properly. In titanium this one is around 195 grams. Inconel will be available in a month.
