[QUOTE="entoptics, post: 2898318, member: 104268"] Been having a heck of a time getting my buddies rifle to shoot well, and by "well", I mean MOA or better. Tried a few different bullets, couple different powders, and never could get a repeatable 1 MOA, and generally it's more likely to throw 1.5 MOA, occasionally worse... I'm fairly certain what I'm seeing on the Teslong can't be good, but wanted a 2nd opinion. The rest of the pipe is nice and smooth, burr and defect free, and cleans easily. Straight on view of throat area. [MEDIA=youtube]vUSshBS-RBk[/MEDIA] Side view of throat area. [MEDIA=youtube]b4Yp9pVU2SI[/MEDIA] This is a drop in Savage prefit barrel, but I won't mention the manufacturer till they have had a chance to address it. 416R, 1:8 5R twist in 7mm-08. Unfortunately it took way too much time and ammo to stumble on to this. Not enough confidence in my buddy's skills, and I was "cobbling together" loads for him with some old brass/bullets/powders, so when things didn't go well, I blamed those factors. More recently, I went to some pretty extreme lengths to identify the problem, including a skim bed job on his tupperware factory stock, and saw no improvements. [/QUOTE]
