Please forgive my ignorance but I am going to order this action and get two boltheads. My experience is rimfire builds, a vudoo and several 10x barrel fits for non repeaters. I will probably order a MCS stock to match my vudoo. My understanding of BDM is limited so is there a specific type brand I would need to build this rifle. Really looking forward to putting something together for longer range than I shoot with 22lr (have a 400 yd range), hope to find something up to 1000. Thanks, Craig
