New Ruger Tips

Post by **Bullseye** » Sun Nov 09, 2008 6:43 pm

This sounds like an urban legend. I have not seen or heard of this condition with a Ruger 22 Auto, at least not on any pistols that haven't had their original barrels replaced. The new barrel's are crush fit onto the uncut receiver tube at a very high torque in the manufacturing process. A sealant (like high-strength Locktite) is applied to the barrel threads. After the barrels are inserted and torqued into the blank receiver tube, then the receivers are indexed off of the front sight hole and cut by a CNC mill. Everything is referenced off of the the barrel alignment in the receiver. Once the tube is cut, the feed ramp is positioned properly because of the indexing set-up. It is this process that makes the re-installation of an aftermarket barrel so difficult. Basically, the whole pistol receiver is built and shaped around the one-piece barrel.

I have more than 300K through my Mark I, and the barrel doesn't show any signs of twisting. I'm not saying it couldn't happen, but if it did, it would be an extremely rare situation based on the factory production methods of these pistols.

If the direction of the rotation of the barrel is opposite of teh direction of the rifling it would be self tightenin.g Old horse drawn wagon had left had threads on the left side so that the rotation of wheel would not run them off.

now, why didn't *I* remember that... ?

actually, I recall an old buck-board out behind grandma's barn...
not that I specifically remember this detail, but it seems that
the "lug nut" was notched with a hole in the stud...
to use a cotter-pin... not unlike my current car wheel-bearings...

have a good week...

Anyone familiar with aircraft also know these as Castle Nuts.

If there were such a significant "twisting effect" or torque imparted on the barrel by the bullet, wouldn't we feel it? On a good shot, my front sight jumps straight up. I have never felt a gun twist in my hand, of any caliber.

True, for every action there is an equal and opposite reaction, but I think we would feel the torque (especially on a .45) if it were strong enough to loosen the barrel. The effect must be there, otherwise the bullet wouldn't spin. But depending on the twist rate, it is relatively weak. That's my theory anyway.

I've noticed the torque effect when shooting the 45. My wrist breaks up and to the left in a slow fire stance. It is also pronounced when observing a new shooter, when they shoot the 1911 for the first time one-handed. I haven't felt it with the .22, but it has to be there, just a smaller torque force.

My carry gun is an SA Micro Compact or an SA v-10 both short barrel guns. The Micro has an aluminum frame and rthe V-10 steel. The Micro weighs 2 ponds loaded and the v-10 2-1/2. Shooting them one handed you can feel the torgue, especially with the lighter frame having less mass below the center of rotation ( your Wrist ) makes it felt even more.Even more noticeable whan shooting one handed left as the force then twists your wrist in the other direction from your arm.
