Ronin,
Derek is doing some work for me as well and as you say he is now very very busy. It seems like only yesterday when he first started and now his order book is pretty full....just goes to show the demand here for good custom work...
If I was to go for a mag feed rifle I like the idea of having the Timberwolf action which can also take the .408 CT. This means the magazines will be plenty long enough to load a .338 or .30-338 out to the lands. What are the triggers on these actions like?
My only tactical rifle with a mag feed option is a Unique Alpine and the replacement trigger I got is very good for tactical comps - crisp 1.1lb let off. My Jewel triggers are much lighter - about .5lb - and set a bit too light for tactical comps although you can always change this - which is what I love about these triggers as they are great at any of the three supplied springs weight categories.
I have tried some Police triggers and Army triggers in AI's and the 4lb "safety" pull is hard to get used to when shooting rifles which have triggers much lighter and crisper....
If the Timberwolf trigger is one of the "heavy makes it safe" type I would much prefer a Surgeon set up which can take a Jewel trigger. Unless ofcourse the Timberwolf has a Remmy hook up which can take a Jewel? ( Editing to add - "Checked web site and this rifle can take a jewel trigger" - great option ).
If you can get one it should be a cracking investment because of the scarcity

......but with all the military contracts you might well have a long wait
