That's another first for me. Never heard of it.The Post 64 Mdl 70 Winchester were among the first free floated barrels offered. These rifles came with a plastic shim to be placed under the barrels when not shooting. when stored without shims the stocks warped.
What matches, targets, rifles, ammo and scores were used; specifically?Many records were established by both Military and Civilian shooters with fitted barrels
Now that is interesting history.What matches, targets, rifles, ammo and scores were used; specifically?
Of course, that was common in the early to mid 1900's with M1903's, M1917's, Winchester 54's and 70's. Highest scores were shot on big targets with 3 to 4 MOA high scoring rings with 2 MOA match ammo/rifle as the norm. That all changed in the 1960's when 2 to 3 MOA target high scoring rings came about and 1 MOA ammo/rifle was needed.
Yes, I think you did.Did I mention I shot a sub-MOA 6-round group the other day without waiting between shots,
Shim under barrel to float bedding area. Lug and receiver are floating in the acraglas
That would transfer all external pressure on the stock fore end directly to the barrel. Those forces vary with how the rifle's held and rested. The barrel would bounce off of it as it vibrates in all directions while the bullet goes through it. Vibrations have amplitude.Otherwise i assume a pressure pad at the front of the barrel channel, or bedding the full length, would used if one were actually try to create pressure, support, what have you, on the barrel.
Even at lower altitudes, there are sticks and leaves and entomological wonders. Some folks take their rifles other places than from the SUV to the mat on the firing line.I have hunted all these years in the Rocky Mtns. A totally free floated barrel used at high altitudes may be a poor choice. Wet snow and ice will freeze in the barrel channel. The fine Austrian and German Alpine hunting rifles have close fitting barrel channels. This is my opinion make your own choices.
Those vibrations start when the firing pin smacks the primer. They get bigger when the round fires. There are several different frequencies involved. They quit after the bullet is past the muzzle.When bullet travels down a barrel you get harmonic vibrations. You want these to be consistent shot after shot. Just my opinion.
All actions (receivers) epoxy bedded have stress and are slightly bowed upward in their mid section by the free floating barrel weight. If the barrel is full contact bedded in the fore end, the receiver may not be stressed until the round fires; then it will be stressed.the reason for bedding is to stress relieve the action.
