Highest Velocity For Lead in a Rifle

The only ceiling I am aware of is degredation of accuracy and leading. If either of those happens you are pushing too fast. The fastest speeds with lead can be obtained by paper patching the lead bullet,

I understand that some shooters have acheived acceptable accuracy up around and a little over 2000 f.p.s MV. Doubt you'll make that with the .30 Carbine, though. However, your BEST accuracy is probably going to be somewhere between 1500 to 1800. The harder you push 'em, the harder you'll want your alloy, as a general rule. Regarding gas checks: the only difference today between Hornaday and Lyman checks is $8 or $9 per thousand. The checks are the same. Hope this helps.

Wes According to Richard Lee, Hornady is actually the sole manufacturer of gas checks. As far as lead hardness goes, I have heard there is a way to test it with pencil graphite, as opposed to the actual Brinell Hardness Testing tools that are out there. Is this way nearly as accurate? Or should I just bite the bullet & plunk down the cash for the damn tool? If doing so, I think the Lee device sounds the most economical, but does it provide the same result(s) as the tools costing 2-3x as much?

I have used the Lee tester on known BHN numbers and it is spot on if you take the time and read it right. Have a good light .

I can get 2400fps out of my No4 MkII .303 Brit with great accuracy.

Slow powder, hard lead, tight fit.

I had very bad luck casting for the carbine. The General Motors version was sluggish for one thing and broke the extractor in the jam feeding when loaded for accuracy. Maybe if you can cast linotype it would be fine. Leading etc was never an issue as it hard to get a lot of powder in the little case.

Linotype alloy can handle up to 2,000fps with a good fit. Wheel weights and Lyman #2 alloy will shoot ok in the range of 1,400-1,600fps. Lead like 20:1 with tin should stay down around 1,000-1,100fps in fixed amunition.

Since you are going to test for bhn, it seems to me alloy bhn hardness coencides with 1,000fps+ velocity. Where 12bhn will shoot ok at 1,200-1,300fps, and 16bhn will shoot ok at 1,600-1,650fps ok. Just a general thought. Tech books will get into much more complicated formulas concerning tensile strength etc.:( ........Dan

I have gotten up to about 2,400 fps Cronographed, accuracy wasn't very good at that speed. The higher velocity with very hard alloys you may have break up before it hits the paper. I use a synthetic lube, at least 2 lube grooves, on many of my cast bullets.

Lee Alox isn't that good, try Xlox I use it on many of my cast bullets, especially my Ranch Dog bullets. It is much cheaper than Lee Alox. Xlox can be had from White Lube http://www.lsstuff.com/lube/liquid-x.html

Thanks for ice on the Xlox lube. Is it applied exactly the same as Alox?

Reading the label you so graciously posted says it contains petroleum distillate, this must be very harmful. Doesn't have a Sierra Club approval either!

What the heck. I'll bet none of us have Sierra Club Approval either. For that matter I don't approve of the Sierra Club.

I had a friend who wanted to learn casting some time back, so I coached him & he really caught on quite quickly. He decided that he wanted to hunt deer with cast bullets, and after a bit he bought the moulds he wanted and started load development. He was far enough along at that point that I pretty much kept my nose out of his business unless he asked for help.. He did get a deer with one of his rifles, and was pretty happy about it. One day I asked which rifle he used, figuring he probably used his 356 Winchester. I wasn't really prepared when he told me he used his 375 H&H, with a gas checked bullet at slightly over 2600 FPS! The shot was made at around 125 yards, and the deer was VERY impressed with the single shot my friend fired. He was getting sub-2 inch groups at 100 yards from a big bore hunting rifle,at those velocities, and shot it well. He did think it kicked a bit much, and that he'd probably tone down the load a bit. I was impressed...
