I notice that the M1 has a much smoother and shallower loading path for the new cartridge, and that there is almost no gas blowing back through the action.
They are amazing mechanical puzzles/functional art. Coolest rifles ever, IMO.I notice that the M1 has a much smoother and shallower loading path for the new cartridge, and that there is almost no gas blowing back through the action.
The op rod has the bolt going from lock to unlock in 2 frames which is 1/600 of a second...Nice!
The fact that it ejects the clip out the top automatically is just freaking amazing, and that it all runs on just one spring. It is like some kind of magic show.
Yup. One of the biggest downsides of the star bolt design is that the feed geometry is a lot more complex.I notice that the M1 has a much smoother and shallower loading path for the new cartridge, and that there is almost no gas blowing back through the action.
How so?...One of the biggest downsides of the star bolt design is that the feed geometry is a lot more complex...
Feed angle is necessarily steeper for one thing. The bolt head diameter is effectively greater so the next round has to be lower relative to the bore. Plus you have to figure out how to feed bullet tips across a couple of square gouges in the barrel extension, which are quite a ways back from the actual start of the chamber.How so?
