As the title says, I have recently purchased a Remington 700 sendero in .300 win mag. Sitting on top is a U.S. Optics LR-17, mounted in US Optics medium height rings on a LaRue Tactical 20 MOA picatinny rail.
I am having severe trouble sighting it in. First outing was having trouble with the bolt sticking closed after rounds fired...specifically the first round took some "convincing" to get out. It got better with a little oil, but was still sort of sticky the whole day. Also, we couldn't get the rifle to group less than 10" or so at 200 yards. In the middle of troubleshooting, we ran out of ammo. Took it home, cleaned and lubed, and came back out yesterday. Sticking problem is gone, but still can't get the damn thing to group at 200 yards....
The target below is at 100 yards.
After 1st shot adjusted windage and elevation.
After 2nd shot adjusted 1 click windage
After 3rd shot adjusted 1 more click windage
The one in the 1 ring I believe was the 5th shot.
Looking OKish so far, so we moved to 200 because that's where the zero needs to be anyway...
I shot this "group":
Dad shot this one:
We decided to stop wasting ammo and start troubleshooting, but being hardheaded I finished the box and shot this :
What say Snipershide? I don't have a lot of experience with bolt action rifles, so I'm not sure where to start troubleshooting. I figure it can be one of a few things:
1) Scope has a loose track or is otherwise sensitive to recoil for some reason.
2) Scope mounting is loose (triple checked this, don't think it's the case)
3) Something is up with the rifle. A google search netted me something about the action screws, but this gun is brand new. Should all be factory torqued.
4) Marksmanship, although I don't think this is the issue. My Dad and I are both decent shots and we're shooting from a bench rest. For reference, I can group less than 2 inches at 200 yards with my Winchester M70 7mm Mag.
Any suggestions would be welcome. Oh...and...obligatory gun pr0n:
