I was wondering if anyone has tried shooting aluminum projectiles to reduce weight but maintain bullet length so it stabilizes properly. Any thoughts or comments?

NASA did some research on aluminum projectiles in vacuum but I’m not really interested in hitting hyper velocities right now, I’d be happy with 6000 or so fps at muzzle.

Will I be melting the aluminum at 6000 fps or will it still be good?
I think it should be fine but am interested in your opinions.
 
Aluminum bullets would have to be monitored carefully, since aluminum oxide is very hard and very abrasive. None of those bullets going down any of my good barrels!! Regards, Eagleye
 
i spun one up on a little lath of mine in .40 same size and shape as a 180grain slug... fired it into balistic gelitain... with a normal load behind it(probably could be juiced up allot. Also i never croneyd it either... but it only penatraed 4" or so...and never cycled the action. Quite useless. Also there would be alum fowling in the barrel too. I would think maby a plastic type bullet would be better.
 
Well with a 7grains of hs6 behind it i don;t think it built up enough preasure to get any velocity... I would not doubt if the alum projectile was going slower than the standard lead one... I realy need a crony. Sorry for the spelling mistake. Im strong like bull... but smart like car!
 
As stated above, light alloys are best kept for pistol applications. I recall reading some interesting stuff about pewter. Seems to me they got around 1800 fps from a .357, and the bullet was cast in a Lyman 156-158 gr, mould resulting in an 80 gr. bullet - but I don't remember much else about it.
 
I have a commercial 9mm round with an aluminum bullet. I only have one so I am not going to fire it but the bullet has a HUGE hollow point and as I understand was actually designed to fragment into three large pieces on impact.

Judging from the size & shape of this bullet I'd think it is very lightweight and probably comes out of the muzzle at some hellacious velocity.
 
Using different alloys to make bullets is/was being done in quite an unlikely place - 50BMG LR match shooting. I guess spending $5 per bullet gives one incentive to experiment.

Some have even experimented with STEEL. Yep, can work if the sizing and alloy is right. I guess the first bang must have been tense.

Never seen any accuracy or load data though.

Would be very interesting field to play in with the right monitoring equipment.
