Fluting the top of a barrel only to reduce muzzle jump

Post by dustin » 13 Apr 2014, 12:52 pm

Ok, crazy idea time here...

I couldn't find the 'how recoil works' diagram I wanted to link with this, but a lot of you guys have probably seen it anyway...

Basically it's that just with a barrel and a bullet, if you fired it it would recoil directly backwards like a rocket. The reason a muzzle jumps instead of going backwards is because the shooter anchoring the bottom/rear of it with the stock. You dig?

So questions is, theoretically, if you fluted only the top of a heavy barrel, so the weight was more distributed to the bottom, do you think that would potentially eliminate a lot of muzzle jump? Sort of... Realigning the weight to the centre to compensate for us holding it?

I'm not at all looking to do it BTW. Just turning it over in the old noodle.

so to reduce the unbalanced mass above the center of the bore and below, you want to reduce mass above the center of the bore? seems arse about to me

i'd also suggest that a couple of flutes on top of the barrel would remove just a few grams, maybe 30-50 and it would be so close to the center of the bore that it probably wouldn't make any difference either way. bear in mind a gunsmith could charge you around $80 per flute he cuts

a better method might be to add 50gr of lead to the forend of the stock, or simply fit a clamp on brake which is a proven method of reducing both muzzle flip and recoil

The closer the centre of the barrel is to centre of your stock is the less the barrel will won't to come up. Look at target pistols the barrel is usually lower so recoil pushes directly back into you hand.

Compare the barrel location on the pic below with the ruger in my avatar.

I'm totally open to this being a stupid/ridiculous idea by the way :lol:

I get the direction your coming from, but really I think you're only adding weight as the idea stands.

If it's still held at the bottom, it will still pivot on the bottom...

If you just fluted the top of the barrel when it heated up the barrel would curve and the point of impact would change.

Yep, there is a reason the bore SHOULD be central to the outside contour. If the barrel doesn't have equal meat all round when it heats up it distorts.

Yes, I am aware some very accurate .22LR barrels are purposely off center to the action but they are done like that for a reason.

To reduce muzzle jump in semi auto competition pistols (and a couple of custom revolvers I have seen) the bore centerline is very low.

Yep, that would be the way to do it.

I don't know that I've ever seen such a thing in a rifle, but if you were making some custom jump-less rifle this would be the way to do it, not just moving weight around in odd places.

You'd want something with the barrel in the centre of the rifle some sort of extended trigger system which moved the handle and trigger back/up so you were behind it, rather than under it. A lot like the back of a .50 BMG I guess...

Having said all that though, NFI how that work work in a rifle. Probably be ridiculously awkward, if not completely unusable.
What is this "too many rifles" you speak of?

That I hadn't thought off.

Just a thinking out loud idea anyway, not trying to do anything really.

You gotta work through the bad ideas, right?

You have a good one eventually ;)

Warrigul, Kelix.

Yep I'm good with that. Nothing ventured, nothing gained, right?

Happy to work through the odd ideas to find the occasional gem ;)

Instead of shaving (or adding) weight to the barrel, why don't you modify a muzzle brake to deflect the gasses in a specified direction.

Along with the correct holding technique for a rifle, I'd say this woul be more ideal..

There was a technique called magnaporting,used electro-erosion to cut ports parallel to bore in the barrel to reduce muzzle rise,

Brakes are probably cheaper,can still be made with vertical ports,google artillery muzzle brakes,there are some weird and wonderful.

Be Safe BB.
