Aluminum Bullets

I thought this was pretty neat.

Anybody who casts their own bullets have you ever tried anything different then lead?

Wonder what the energy is.

On the 45-70 he was getting 3000+ ft per second

Based on his claim of them looking like a 500gr lead core bullet and weighing 100gr at 3000fps he is looking at about 2000ft lbs of energy at the muzzle, 1250ft lbs of energy at 200 yards.

Compared to lead core 45-70 FTX from Hornady at 3000 ft lbs of energy at the muzzle and 1500 at 200 yards.

Aluminum bullets need to be long to have any useful weight to them so they will get into the powder space.

(3000 fps x 3000 fps / 450240) x 100 grs (Al) =1998.9 ft-lbs The real question is how often will you have to rebarrel your firearm over the course of its use. The faster the bullet travels the harder it is on the rifling. (1600 fps x 1600 fps/450240) x 350 grs(lead) = 1990 ft-lbs. So a lead load will provide you with a lot longer barrel life.

Aluminum starts acting weird under high pressure/force, I would avoid it or be ready to do A LOT of testing.

Nice video.
Other then the boys having fun,raises the question-why fix it, if it is not broken?

100 grain 3000 fps .45 diameter???
Guess the boy doesn't know a lot about physics.
Why would you even bother trying it?

Would be good to have incase the werewolves come around lmao

Need silver for that. I was going to get someone to melt some silver for me and make a few cast bullets, but I sold the silver got 48 bucks on ounce on kijiji. I only have a half ounce left

Not in my plans, but have watched tons of videos on home propane smelt furnaces which recycle pop cans, copper, brass and stuff. Pretty cool, but not my casting future.

I did up 300 X 150gr RNBT .30 call cast bullets and powder coated them over the last couple of days. Pictures to follow. The are primarily for 30-30, Lever
