Well...its been several months since I completed my m4 variant. After several trips to the range and nearly 1,000  rounds through her, she finally seems to be settling down and shooting consistently tight groups. The barrel is broke in nicely and there have been no malfunctions, even with different loads of ammo though it. Being an avid reloader, I've taken the time to catalog several different loads that offer pretty nice accuracy without punishing the gun needlessly. She seems to be fond of bullets between 40 to 65 grain range and groups under an inch at 100yards.
Now there's just one question I am constantly asking myself.....what do I want to build next?

Something big bore. I prefer the 458 personally.
