Put some function test rounds down range through my OBR last weekend. Just ten rounds of 147gr Portugese surplus double and triple tapped. Recoil is very mild. The Surefire muzzle break is really loud.
Awaiting the arrival of an OBR 34mm mount for the S&B PMII, Magpul PRS with receiver extension/buffer/spring, Harris bipod on LaRue mount. Next purchase is a Surefire suppressor, followed by a decent LASER range finder, spotting scope, and likely the Knights Armament iPhone ballistics software.
BUIS on that rifle is a complete waste. If that S&B PMII fails, just throw in the towel. BUIS with an etched reticule optic is unnecessary. It doesn’t look like he has the correct height rings to clear the rear iron anyway.
Some of the parts came in today. Just waiting on the PRS. Anyone need a set of used, like new Badger Ord steel 34mm M40 rings from my first pic?
Does anyone have experience with Silver State Armory’s 7.62x51 match offerings? Was going to pick up a mix of various manufacturer’s stuff to see what this rifle likes best.
You should check out Ballistic: Field Tactical Edition ballistic calculator for the iphone. I’ve tried both it, and KAC bulletflight; and think Ballstic FTE has some advantages.
I have a JP 308 with an 18" barrel and 1 in 11:25 twist rate. Your groups should tighten up with 165gr+ bullets. At least that was my experience.
Although I was shooting WWB 147 gr. fmj and getting 2" groups. Once I shot 168 and 175 gr Federal Sierra Match King BTHP it became sub MOA. It may have been more than just a difference in bullet weight.
