lol, I'd like to know too. :)

Once my new rear sight arrives I hope to get some shooting done and test the takedowns return to zero of the Nodak Spud sights.

That's a crazy cool 10/22. Keep us updated on how well it shoots, I'm curious what the 9" barrel can do. Planning to one day do a similar build in a non take down version running either a Dlask 8" or 12.5" barrel.
 
I'm working on a few ideas on how to test my takedown.

With this project I wanted to make a lighter and smaller rifle than the stock Magpul Backpacker takedown.

I got a smaller and lighter rifle now I'm going over my testing methodology.

I want a rifle that's super compact back can still take small game out to reasonable ranges. Everyone might have a different idea of what that distance might be. I'm hoping for head shot accurate to 15m with either irons or the red dot and body shot accurate maybe to 30m+. I'm not a great shot with irons or a dot, partially due to my astigmatism and also due to limited practice.

I do know from experience that with a red dot and a 9" Dlask barrel I can shoot placed clays out past 100m.

I think to test the take down I will setup a line of golf balls to shoot. I will shoot one, break the gun down, assemble and load, then shoot another. I think I'll do this 10 times. After that I think I'll use the same process but shoot for a tight group.

I'll do some testing with the red dot too for accuracy but the dot shouldn't change poa and poi since it's mounted to the barrel.

Anyone care to share their ideas on range and/or test ideas?

I'm interested in the accuracy ranging from 50-100m using bulk ammo (~1250 fps). Assuming my math is correct, with a 9" barrel the bullet transitions from supersonic to subsonic around 20-25m. With a transition so early, I'm curious how much the bullet get's thrown off by the time it makes it to 50-100m. A standard 10/22 16 inch barrel in comparison transitions from supersonic to subsonic around 50m.

When you were shooting clays at 100m with the 8" Dlask barrel, were you running subsonic ammo?

I apologize for getting all geek out, it's just that I've been thinking of doing an 8" Dlask build for quite some time now. Then I saw your incredible build!

I'm not a great shooter with irons or a red dot so I'm unsure if my ability or lack thereof would skew the results.

I was running CCI blazer from the 500 round bricks shooting clays out of a 9" Dlask .920 barrel.

This was the rifle I used.


I'll see if I can shoot groups out to 50m, it'll take a few weeks likely to get any shooting done. This is a busy time of year for me.
 
I bought a stainless takedown from Wholesale at Christmas a couple years ago for around $400 and it's now mounted in a magpul backpacker with a skinner rear sigh and the barrel mounted red dot rail...... the rest is stock.
I still haven't tried the rail but the iron sights shoot dime sized groups at 25 yards with bulk ammo.
