I’m at a bit of a loss for words after my trip to the range this morning. I started the morning by going to a public shooting pit. Goal was to get velocity info for a few different rounds I have for my 300 prc, mostly out of curiosity since I just picked up a chronograph. I already knew what ammo I was going to zero the rifle with as well today. I setup a target at 100 yards and realized I wasn’t even on the box let alone on the paper. I tried to spot my shot and it seemed to be going way up and to the right. I attempted to adjust a few times and get closer, but had no luck.
I moved the target into 50 yards with pretty much the same result. I gave up and went to the public range that has benches.
When I got to the range I set the target at 25 yards and stil had no idea where it was hitting. definitely not on the targets i taped up. At this range they have so sleds so i grabbed one of those and boresighted at 25 yards. Still not on the paper but i was able to land a fee at other spots on the 3x3 backing for the targets.
Based on the trip today, I think something is loose or not seated properly. Maybe i messed something up this week when i was retorquing everything down and applying fingernail polish to the threads.
My question is, should I tear the rifle down in a certain order to diagnose things and if so where do I start? Prior to today this rifle has been extremely accurate.
For info, i'm running a 300 prc christensen in an xlr element 4.0 mg. the scope is a maven rs1.2 on a pic rail with leupold back country rings.
