Just tried out some 100 grain aluminum bullets in my 460 Weatherby. Used 110 grains of H110. I've got to try shooting some of these at night because even in broad daylight the muzzle flash is amazing.

Good varmint load ;)

I'm tempted to try them out. Probably out of my 458 Lott though. I can shoot it a lot more accurately than the Weatherby.

How's the aluminum on the barrel?

Not sure yet. I've only fired eight of these so far working up the load. I do have obvious aluminum fouling in the bore that I'm not sure how to get out. Have only ran a few patches through it to get the powder out.

Where can I get those bullets and is there loading data for the 45/70?

Here is where I got them: http://lehighbullets.com/products.asp?cat=32 They do list 45-70 data, but only with 2400.
 
Very interesting, I'd love to see the terminal performance of this round. I"m willing to bet it won't dissapoint ( I'm guessing very shallow and rapid/aggresive expansion). LOL the sectional density would be 0.066.

your rilfes throat sure isnt going to live long shooting massive doses of 110 out of it!

That's for sure.

I was able to get Barnes X 160's up to 4000 fps. out of a custom 338/378. Fortunately or unfortunately they didn't shoot. I've been meaning to retest with the newer 160 gr. TTSX's just for fun but haven't gotten around to it. 110 gr. of pistol powder does sounds like a good way to ruin a bbl quick though! lol With a slightly slower powder you could still get ridiculous velocity with probably less wear and tear.
 
Interesting. The B.C. on a 100 gr. .45 caliber aluminum bullet is going to be extremely low. Since it will probably shed velocity like a ping pong ball, but I'd be curious how it'd do at 100 yds.

Actually, a alum. bullet will be lighter so it will be longer than the weight might suggest. A 100 grain alum. bullet might have the same BC as a 300 grain copper slug.

I could be wrong, but I don't think so. Think: standard golf ball. Now think: foam golf ball, plastic golf ball, etc. No matter how fast you start out the latter, they slow down WAY quicker than the former.

I'd be very interested for the OP to calculate the B.C. This could easily be done by shooting it through the chrono near the muzzle then again at, say, 100 yds. The difference in the velocities at the two different ranges could then be used to figure an approximate B.C.

What powder did you use? I was going to post in the reloading section about what powders to try out with these bullets, but every time I have posted something like this before I just get a bunch of responses about how you can only use published data or you will blow your gun up. :fire:

I would be really worried about shooting my chronograph at that range. Guess I might have to try them out for accuracy first.

35 Whelen, yes the bullet will slow down much faster than a lead cored heavier slug, but take a look at the photos of it. It wouldn't be all that out of place to have a couple as coyote or other varmint critter .45-70 round for opportunity shots. If you think it's worth shooting at an animal that isn't your main prey, more power to you, might as well save your deer or pig rounds for some day when you aren't scaring them away.


Maybe.

Interesting, but I wouldn't use these on a regular basis.
Fouling aside, aluminum quickly forms a transparent skin of aluminum oxide.
Which is what they make grinding wheels out of. :D
 
I'm still trying to get my head around 110 grs of H110! :eek:

Yeah, I was a little worried firing the first one off. No signs of pressure though. I actually worked the load up to 118 grains, but my chronograph only recorded my shots up to the 110 grain load.

According to the manufacturer, "The bullet is made from aluminum and to eliminate the potential for aluminum oxide formation, the bullets are coated with a dry film lube immediately after they are cleaned."

Can you pleeeeeeeeeeeeeease make a video of this hitting some water jugs

Will do. :) I might get to the range tomorrow, otherwise next weekend for sure.
 
Made some videos. The first link shows a single bottle being shot and the second one is a line of bottles. Recovered what was left of the bullet in the third bottle. Came back later to do some night shooting. The muzzle flash was like setting of a small nuclear device.

Gotta ask why would you want to run those?

Because I can. :neener: When I first saw them, I plugged the data into quickload and it predicted a muzzle velocity over 5000 fps. Obviously I didn't quite get there, but it's still pretty impressive. It is tempting to try these out as a varmint round. I still haven't shot them for accuracy though.
 
I don't know why, but this just fills me with delight. Not much penetration, but varmints don't need much. I hope it's a laser beam for you.
