Running Boar barrel profile

[Fast14riot]

Anyone ever use the muzzle weighted running boar profile anymore? It saw some resurgence in the early 2000's among rimfire shooters, but has it ever been used much in centerfire? I have a soft spot for old designs and oddball stuff. My dad had a 10/22 with a running boar barrel, shot well, too.

Please define. I have never heard of such a thing.

There was a time (at least here in S AZ) they were used in Silhouette shooting. I recall them being referred to as a Donkey D*ck barrel. Early 80's maybe?

Supposedly it adds weight to the end for better off hand shots but still allows smaller contour to fit the stock???

Interesting. I bet I would like that for shooting jack rabbits. I like long light nose heavy guns.

Looks like a great contour for adding a can to a skinny barrel.

One of the 2nd tier barrel makers is doing just that. Can’t remember which one offhand. Another for suppressor use are the straight/taperless barrels which I think Preferred started offering up first. PVA is also doing them now. I believe they are offered in .680” and .750” diameters.

We did some for brakes on skinny barrels

May not look skinny but is a 500 Jeffery.

I know this is an old thread, but I recently put a Green Mountain heavy muzzle barrel on a new Ruger Custom Shop 10/22 Competition. It made an absolute tack driver out of it. It’s a 19.5” .920” barrel that is 1.06” in diameter for the last 4” of the barrel. The original Runnig Boar barrels originated in Europe for the Running Boar target challenge. Those barrels were .920” at the heavy end of the muzzle. One aspect of that design that gets overlooked is the fact that the heavy muzzle helps eliminate vibrations and harmonics. They were originally designed to add weight to help balance the rifle better. I will post a link to a short version of my video where I show its effectiveness. This rifle also has the Kidd two stage trigger with a total pull weight of 6 ounces. Everything else is factory parts.

For actual running shots, you want minimal muzzle flip/jump. The extra mass on the end would reduce the flip, help with quicker follow up shots. And seeing shot impacts.

That makes good sense! The added bonus of eliminating the barrel whip is a great plus also. Mine shoots about as good as my good bolt action 22’s.

You don't see them in Silhouette much anymore because the reverse-taper barrels only qualify in Standard rifle, not Hunter, and most people set up one Hunter rifle that they can shoot in both classes rather than having two separate rifles.

The Mexicans don't have a Hunter rifle class, just the one (what we call Standard rifle). You'll see a lot more rifle that have extra weights that are added on the end of the barrel rather than a true reverse-taper barrel. Much easier to adjust to your preferences on balance.

If you think about it, a barrel that has fluting near the chamber but stops well short of the muzzle end is basically accomplishing the same thing... keeping more weight out at the muzzle and lightening the middle. You see this a lot in Silhouette because you can use a slightly heavier profile barrel with the weight cut down in the middle but left whole for the last 6 inches or so.

Depending upon the process and timing of when/how a barrel is fluted, the process can result in the bore loosening. If performed by a competent smith, specifically the barrel maker, then this isn’t a concern. For this reason barrel makers won’t accept warranty claims on barrels that have been fluted by a third party (voids manufacturer’s warranty).

Based on this potential issue, it was my understanding that the fluting is terminated short of the muzzle to ensure that final section of bore remained concentric and tight for best accuracy. Also, it provides sacrificial section for threading (if desired).

Practically speaking, adding a suppressor or barrel tuner accomplishes the same thing.
