new muzzle brake for LTR

[yoyo]

I just made a muzzle brake for my .308 LTR. The recoil was not bad but I would like to watch the hit from my scope. The muzzle is threaded to 3/4" X 1/28" to keep the removed material to minimum.

The fit between the brake and muzzle thread is tested

Then finally side venting holes and a top venting hole were drilled on the brake

This is what happens when the gun is fired

There is no muzzle raise and the recoil is reduced by about 30-40%, there is the first 7 shots groups shot at 100 yards, 10km cross winds. measures about 1.2inch:

then moved to 200 yards, 3 shot groups are in the 1 inch range. But the best thing is that after 50 rounds my shoulder is not even feeling a thing!

Copper wire on the chuck jaws.......... very clever....

Must have been tricky getting the wire alighned with the "hi-points" on all the jaws to centre the barrel.

Nice work.

The copper wires works better than I thought and it's well worth the effort. Run out of the muzzle was about 0.0005" once the wires are on the high spots of the jaws.

Nice, machinist have a lot of cool toys, er tools
Interesting design with a port at 12 oclock.

one vertical venting hole is just about perfect to counter react muzzle raise when shooting off sand bags. For off hand shooting I think it needs at least 2.

Very nice, you don't have a 4 jaw chuck i take it, even though 1/2 a thou is pretty good for a 3 jaw...
