what, in the design of the 311413 causes it to be inaccurate (in most cases) at higher velocity?

which end do you want to start at?
the overly long gas check shank, the extruded lead into the lube grooves, the scraper type drive band at the front, the unsupported nose, the pointy tip on the end of the unsupported nose, or the too square lube groove walls?
the nose shape is the least of it's worries.

other than that it's wonderful.

It's a simple, two-diameter cylinder which doesn't fit any throat shape known to man. Lack of support in the right places during HV launch causes crooked starts which cause the thing to be unbalanced once it comes out of the barrel. Unbalanced bullets don't group well at HV.

If you're thinking it's the pointy nose "slumping", you've been reading too much speculation by those who don't understand dynamic fit.

aaand we overtyped again.
I thought we only done that on Tuesdays... oh and Saturdays.

The back story is that it was Lyman's answer to the Belding and Mull and Modern Bond designs of the Miller-Squibb bullet. Those two guys from Long Island spent years working on the best 200 yard bullet for the 1903 Springfield. Since it only had to do 2 MOA, but feed 100% of the time, this is what they came up with for the design. Yes, I know, old time thinking (the scraper band was suppose to reduce bore fouling) and big lube grooves for lots of "Banana Lube" for their 15% antimony and 10% tin alloy. "Dynamic Fit" wasn't even thinkable. Still, if you can mechanically fit and align it to the throat, it isn't a bad subsonic plinker.

it'll shoot and shoot up to the standards it was meant to shoot in.
but it isn't meant to be bowed up under pressure.

I have Lyman, Belding and Mull, Cramer and Modern Bond versions of this bullet. I read to much really old stuff for my own good.

15% antimony and 10% tin?? Hijo la, how did those bullet ever get bent outta shape?
Well, they didn't get bent. Another common alloy was 18% antimony with no tin. Lots old stories of buying block antimony and pulverizing it with a hammer, grinding it and covering it with charcoal and trying to dissolve it with the lead on natural gas burners. The "common knowledge" then was that if you made the bullet hard enough, it would straighten out in the barrel. Plus they were not straight in the chambers either when fired. Remember that military shooters didn't require anything over 2 MOA, unlike the Schutzen crowd that was doing about one and a quarter MOA at 40 rods.

If you can find copies of the old Rifleman and other periodicals of the day, the "Squibb" design was a common subject. Everything I have read boils down to a not real great design failing at higher speeds. It's a "bullety looking bullet" to quote one writer back then, but it's just not a great design. Fiver and Ian covered the problems.

The scary part is that the Squibb was a lot better than some others that came along back in the day!

a lot of them were fired in the armory [remember those?] to simulate 300 or 600 yard shots at much closer ranges.
they scaled the targets down to like the size of an Aspirin, and let the soldiers/guardsmen shoot.
you didn't need anything real fancy or fast you needed something that could be made and loaded on sight then chambered and fired by ham fisted conscripts.

Charles, wasn't there a very similar looking Lyman design for the 300? I don't have the books here, but it sure seems there was one made up just for the 300 Savage.

Yes, 311414 - 150 GC with much the same nose but a short body for the 300 Savage case neck.

I have a Cramer 30 cal in that design and a Lyman in a 270 cal . I can't swear to it but I think probably the Herters 25-80 is also .

I've been tempted to cast the 270 in something like lino/WW and paper it to 7mm just to see if it's really a lousy design or just a bad naked bullet design . Of course I'm sure someone has probably done that with 12 alloys , 9 powders , and 3-4 papers . I might try the 25-80 that way too but in a 264 WM that might be hard to get anything useful whether or not it's any good that way or not . I have a couple of more sedate cartridges in 7mm .
