Hello Everyone,
Rifle Specs:
Seekins SP10M 6.5CM
March 4.5-28
Area 419 1 piece cantilever.
TBAC Bipod
Ammo.
135 Berger Classic Hunter
2.810 oal
Don’t remember BTO off top of my head
42.1gr h-4350
Alpha LRP 1x fired brass NOT annealed
Fed 210M
Heavy Taper Crimp
1/2-3/4 moa
SD typically 7-8 fps
2,850 FPS
I’ve been putting a lot of time behind my SP10M in 6.5CM lately. The rifle was absolutely hammering. Outshooting bolt gun buddies out to 1,300 yards. It’s literally the most fun I’ve ever had behind a rifle.
Anyways over the weekend I took the rifle out, checked zero. Shot 3 inside of a quarter. Adjusted scope right .2 and down .2 Another quarter sized group. All velocities recorded via garmin while zeroing 2848fps average. 6.5sd
Rifle is zeroed
Then i dialed for 700 and sent it. Miss right, correct for wind, miss farther right, correct further for wind miss way left.
Hmmm. Let’s step back to 500
Miss way high, miss way way low, left, right. Extremely erratic.
Getting nervous now. Back to 100 yards
Same ammo 3 shots about 1.5-2 moa group.
Uhhh ohh. Grab some factory loaded 142 smks from Defender ammo. 5 shot group 3-4 moa
Okay, scope must be loose.
Check mount with torque wrench
All screws correctly torqued.
Put fresh paper up at 100 yards
Anchor rifle down tight on metal bench
Dial up 20 Mils, then down 20 Mils, back to same spot. This isn’t a proper tracking test but it’s what I got.
What the hell has happened to my baby?
