Benefits of technology

[0010]An advantage of the present invention is improved firearm accuracy and uniformity from shot to shot.
[0011]Another advantage of the present invention is that for a rifle the device is preferably mounted to the barrel through the rifle's wooden forearm or stock, where the strongest vibrations typically occur.

Problems solved by technology

When firing a projectile through a firearm, vibrations in the firearm barrel are caused, which results in lower targeting accuracy and less uniformity from shot to shot. FIG. 1 schematically depicts vibrations 12 of a segment of barrel 20.

example 1

[0027]A .256 Newton custom 98 Mauser rifle equipped with the vibrational stability device of the present invention was test fired by a shooting and ballistics expert using a variety of ammunition at various loads. Referring to FIG. 2a, recess 30 was located 8.50″ from the muzzle. Post 10 was 0.375″ in diameter and 500″ long, and comprised a 0.185″ diameter hole with 10-32 TPI threads. Female escutcheon 40 was 9 / 16″ high, comprised a 1¼×¾″ diamond-shaped top as shown in FIG. 2b, and comprised edge 45 which comprised a 6° bevel and was 0.25″ high. Swivel hole 60 was 0.145″ in diameter. Testing showed that there were effectively no signs of high pressure due to the installation of the device, with a maximum case head expansion of 0.002 and only one instance of slightly sticky bolt lift. Bullets of various weights and loads shot monotonously to the same place. Ten shots were fired into two inches using 85, 100, 129, and 140 grain weight bullets in five loads; all but two of the shots fe...

Abstract

Apparatus and method for controlling vibrations of a firearm barrel to increase firing accuracy and shot uniformity. A post is attached to the firearm barrel, and a locking bolt is screwed into the post. In the case of a rifle or similar weapon, the bolt preferably extends through an escutcheon which serves to attach the stock to the barrel.

Description
