i will give one good example. perhaps others will chime in, and we can end up with a complete list of pros and cons.
belted magnum;
one big benefit that stands out, is it's ability to chamber and shoot other cartridges for which it is not specifically chambered for or headspaced for. that is to say, the belt provides headspacing, without regard to shoulder to chamber spacing. an example would be the 300 ackley's ability to shoot other belted cartridges.
There was an article in Rifle Magazine (I think) a few years ago on a catastrophic blow up of a Weatherby rifle. The shooter fired a 7mm Rem mag round in a 7mm Weatherby rifle. The bullet jumped from the case but did not enter the barrel and continue on. The case expanded and did not support or guide the bullet into the barrel. The bullet plugged the barrel at the throat and the chamber became a bomb as the action destructed.
I could see this happening with a number of belted cartridges that were short for the chamber but still had "correct headspace".
You have been warned.
Dennis,I know it does not take much to blow up a Weatherby but I doubt the 7mm Remington round fired in a 7mm Weatherby chamber would do that.. they are just too close in all aspects. It must have been something different...
Dennis,
I think that the Rem cartridge was enough SHORTER than the Wby chamber that the bullet was not guided into the neck with pressure at the base to cause the bullet to continue down the barrel. The case immediately expanded and allowed gas to fill the area in the chamber but NOT adequately focusing the force behind the bullet. The bullet simply plugged the barrel at the rear and would not allow the gas to escape down the barrel.
I think that the same thing could happen with any action, this was not any fault or sign of weakness in the Weatherby action.
