    Is this a question of the weight of the bolt?!!
    For goodness sakes, are we talking about a few grams or ounces??
    For my money, I'll take a good machined piece of steel over some hunk of plastic. (Sorry, Glock owners)

    A Stolle Panda action is mostly aluminum with steel inserets. It makes a difference in BR to make weight.

    Does anybody remember the Chevy Vega? GM took a tried and true design, an aluminum piston running in a cast iron cylinder, and decided to tinker with it. Wrong move! They cast a high-silicone aluminum block without cast-in iron sleeves, finish-bored and honed the cylinders, then acid-etched them to expose microscopic buttons of silicon for the piston to ride on. Then they plated the aluminum pistons with a thin layer of iron. The entire goat rope was designed to save a few pounds of weight by eliminating the cast iron sleeves, and a little bit of cost in the casting process. There was no way to replace a piston in field service, because of the sophisticated honing and acid-etching process. The experiment was a colossal flop. Thousands of those engines got retro-fitted with flanged cast iron sleeves and conventional pistons by machinists like me, and we made a lot of money from some GM engineer's stupidity! A piston failure didn't imbed it in somebody's forehead, however!

    Hahaha!!! I remember those well, and if you got the thing too hot it would pull this miracle coating off the pistons and cyl. walls. Then you had a $5000 Mosquito fogger.

    My wife had a Vega ("Brightest star in the Galaxy") and it was p-poor. We lived at the bottom of a steep hill and it wouldn't climb the hill if it was loaded down and with the driver and a passenger. The passenger had to get out and walk to the top of the hill.

    What a junkwagon.

    On further pondering:

    A composite bolt would be possible if it either had a steel cap at the rear for the cocking surfaces, or if the rifle used the cock-on-close mechanism of the 1896 and earlier Mausers, Brit Enfields, or the M1917 rifle. Possibly lighter, but more machining operations. Thing is, when all is said and done, you've got a steel bolt head and a steel striker mechanism, with just the center tube of your lighter material. Probably not enough of a weight savings to justify the trouble.

    You could do an aluminum receiver easily enough, provided you followed the AR-15's lead of locking the bolt into the back of the barrel as opposed to the front of the receiver. The main problem here would be keeping the bolt travelling back and forth in such a manner that it doesn't gall up the receiver. Plugging in steel bearing rails would be a possibility, but would need to be done in a was as not to raise the cost prohibitively.

    I still say you can cut about as much weight by just spiral fluting the bolt body with half the expense and without sacrificing any strenght in any critical areas.

    The bolt is pretty much next to my face. I will pass on this idea.

    A spiral-fluted bolt looks gay. I'll stick with the regular bolt and eat the weight.

    You have never encountered a cyclist have you. That is what they strive for. Having ridden everything from 50+ pounds gas pipe specials, to the super nice titanium bicycle, it makes a difference. Not every gram of course. But the difference between the two is staggering.

    Would someone with a scale weigh a few bolts?!
