I recently build a 338 federal LR308 and I am struggling with getting it to cycle properly. After a great deal of adjustment to the gas block, it gotten it to fire and eject the cartridge but it will not chamber the next round. There is also significant scratching to the bullet and casing. I’ve taken a dremmel to the feed ramp to polish it but it only slightly lessened the scratches and continues not to feed. The rifle is built on and SLR B-30 receiver set with a Wilson Combat barrel, a JP Enterprises low mass 308 BCG, Superlative Arms adjustable gas block, Geisselle two stage trigger, Radian Raptor charging handle, Magpual UBR Stock with an Armaspec SRS AR10 spring and similarly high end parts. It has the most expensive components of the half dozen rifles that I’ve built and yet it simply will not work properly. I’ve attached a few videos showing what it’s doing. If anyone has some advice I’d appreciate it.
