Outlandish accuracy expectations?

Trying to sight in my SKS, not having much luck with the accuracy/consistency. Details:

  1. Iron sights
  2. Norinco 7.62×39 122 Gr. FMJ
  3. Tapco stock

Shots:
1 to 10: 30 yards. I knew it was shooting high, and I was adjusting the front sight
11-12: 30 yards after adjusting
13-20: 100 yards. zero consistency, 8–10 MOA.
21-25: back to 30 yards, to see what’s going on. Seemed decent.
26-35: feels like it’s shooting all over.

Am I expecting too much from this rifle?
Do I need an optic to get this thing to 3-5 MOA?
User error?

Project Planning Guidance

Creating a personal project & new to fusion. Thought I needed 3 components, now realizing that joints require separate components to work, so I need 5:

https://preview.redd.it/fafzn150wp0h1.png?width=2064&format=png&auto=webp&s=87ced7396f4af8b58d9b6593048942567ed77c89

Orientation:

  • 1 is a moving "part" of 2.
  • 2 fits inside of 3
  • 3 magnet attaches to 4
  • 4 slides in and out of 5 (with a screw to fix once it's at the required length)

I tried creating a new component and dragging the bodies/sketches to it, but it leaves the timeline steps with the old component.

  1. Is there a clean way to move things around?
  2. If I can't move around, do I need to restart or do I just not use joints for this one?
  3. Any good videos on component / orientation planning? Some of my parts are meant to fit inside of each other, and I'm drawing them facing each other, which is proving to be a pain in the arse rotating/aligning. Guidance would be appreciated!

So I made a butt stock for the tapco chassis.

PETG (orange) attaches to the stock with a replacement M3 bolt, and a dovetail for the TPU (black).

Building a butt plate for a SKS. Yes...I'm bored...new to fusion...it's a project....

Creating in 2 parts....

(1) A Butt plate in PLA - Attaches to the stock.

(2) Pad in TPU - Attach to the PLA section with a cleat of sorts (If there's a name for this, educate me!)

The issue: PLA cleat extends past the edge of the plate/shape.

I tried

(1) remaking the PLA/bottom section of the cleat by creating negative (cut) extrudes on the left & right, but the center still extends beyond the shape (both top & bottom).

(2) Creating an offset plane and moving the cleat section to the middle, and extruding it both directions to the end of the shape, still extends beyond (same as it does now)

Any simple ideas on how to correct?
