Whats up all my m4 carbine forum peeps..Several months ago i created a thread https://www.m4carbine.net/showthread...ot-SBR-Project on my 8" SBR 338 federal project and at that time it was in the finalized stages of completion..Today it is complete and i have chronographed it with some pretty interesting results.. Shooting a few of the Federal Factory 180gr Accubond Nosler Ballistic tips i was clocking in around 2139fps-2171fps and shooting some of the American Eagle 185gr soft point factory ammo i was getting around 2087fps-2106fps...I still have some more testing to do with some lighter loads such as the Barnes 160gr ballistic tips..And i have some video footage that i will be releasing of my test results later this week.But for now i have attached a few photos for your viewing..Please tell me what you think..
