Sounds like a pair of barrel clamps

You got it G.

Drill 2 holes for each plate.
Cut 2 leather pads from the old belt to fit the gap between the holes.



Simple enough to fit a barrel between 2 pads and use the screws to apply holding pressure.
Leather protects the barrel from scratches and excess pressure.



Add as many layers of 2x10 as desired to add height and weight.
Inertia is your friend.

Very basic barrel block setup that will hold any barrel contour and receiver.

Perfect all you need now is wheelbarrow handles and tire! Or just tote it in a wheelbarrow, ultimate shooting accessory. Tote, chase lounge while watching the wind, cooler for favorite beverage...

Well, if its going to have tires, it needs a motor, seat, and a way to steer.

And some armor.

Sort of a down-sized M1 Abrahms . . . call it an M1-Jala-A1.

So my foolish comments aside, do you think it will matter where the barrel is clamped . . . harmonics being what they are?

Closer to the muzzle and chamber as well as in the middle of the barrel maybe?

Just thinkin' out loud.

Or fully dampened with belt full length of wood block? Would think that oscillations would vary with various powder/primer burn rates as well as bullet design/ diameter. Just a thought, enjoy seeing your tests.

Already ahead of ya' Don.
How difficult will it be to drill additional holes to shift the clamp placement?
Take like what, 2 minutes? It's a new test platform and I have plenty of spare time.

Already have a full length epoxy bedded setup, and the Fuglie.
I needed another method of barrel support to play with.

I'm running out of ammo to try.

I've been thinking about doing something along the same line but customized for each rifle I intend to shoot. it would consist of a base with a set of wooden clamps with routed round grooves to fit each barrel diameter and length. The thick bottom clamp would be attached with screws to the base, and the top clamp would be very thin with a steel piece to apply even pressure along the entire barrel but allow scope clearance and attached to the bottom clamp. It would take a little longer to switch rifles of course. In my case I would only need three sets of clamp blocks with different sized grooves. I might just use v-grooves and make do with one set of clamp blocks. Dunno yet. My wood would be fir for the base and probably red oak for the clamp boards or maybe clear pine. There isn't much difference in the price..

CCI VNT 30 grain ballistic tip 22wmr rated 2200 fps

CZ 455 Fuglie barrel block rig with Feddersen stubby barrel

Nobody at the rifle range excepting the RSO who was kind enough to wait while I sent 50.
The noon to 4 RSO hadn't shown up but the man who'd already put in a long morning
waited to allow me to send 50 at 200 before shutting the range down.
There's some good people out there.






Visual check showed irregular case mouths, uneven seating depths
canted bullets, not a surprise from CCI

ES about 250 fps, target results not a surprise either.

Years back I tried something similar to this using aluminum angle and a heavy vise.
It was a vise off my milling machine at work. The thing had to weigh 50 pounds I bolted it to a concrete bench using a pair of 1/2' metal plates.
I set the barrel in a pair of aluminum angle pieces to prevent damage to the barrels.
Made a handy bench tester for the ammo.
I like this project, I'm anxious to see results posted from your testing.

Vise? Bench? Really?





Worked for me too.
