My goal is to build an ultralight backpacking rifle for all North America big game at 500 yards. There are so many custom actions and stocks out there it's hard to know if I've reviewed them all so I'm seeking some advice from knowledgeable members here. I'd like an ultralight action with a 60° bolt throw with integral recoil lug and I'm considering a 300 WSM in an 18 to 20 in carbon fiber Barrel (not set on particular cartridge though). Stock options also seem to be so numerous however the peak 44 looks good but I'm sure there are better out there. My budget is $1700 for the action, $1000 for barrel and $1000 for the stock. I'll be handloading for this. I also have some decent machines at my home shop (Fadal 4020 with 4th, cnc lathe, 2 manual lathes and 2 manual mills) if needed for this pursuit. I did some gunsmithing in the past mostly with Mauser actions back when big5 had the Turkishmausers for $39.99
