Hello, This is my first post here. Not sure if I'm posting in the right place but here it goes. I'm wanting to build a long range lightweight hunting rifle. I have no idea about how to go about all this. Thinking of 300 RUM or a 338? Will be hunting big game. Elk, deer, and hopefully moose one day. Now question is would you guys recommend building complete custom? As in buying barrel,stock,action,trigger from different mfg. Or buy a gun I like and do a few upgrades? Or just buy some mfg. custom long range gun? I would be willing to spend around 4000 for the gun. Any ideas/ thoughts would be nice. All this will be new to me. Thanks guys!
