Thread: Short fatties vs long slender ones...

Lifelong 2 firearm lusts - 375 H & H and a 308 Norma Mag.
The NM has faded but the 375 H & H is still strong as ever.
Would be a total waste of time and money though as I no longer tramp the hills.

Sorry OP, getting OT here. (It's an old age thing....)

Well, @zimmer if your lust is strong enough I’ve got a Sauer 375 H&H with enough ammo and components to last two lifetimes....toying with reducing battery to 416 Rigby and 9.3x62...

Greetings Zimmer,
Yes true Zimmer as we age our need for interesting rifles declines but our desire for them increases. I and likely you as well do not actually need most of the rifles in our cabinet but our declining remaining years prevents us from selling any, as they all have memories and increases the desire for more. Only the tales of the depression we heard from those who were actually there, plus a frugal outlook, prevent us from filling new cabinets with interesting but largely redundant rifles. This is a struggle fought out between different parts of my mind on a daily basis. In your case get the .375. If nothing else they make very satisfying hole in a sheet of paper. Perhaps another generation will take it hunting.

My understanding is we measure barrel length from muzzle to bolt face, not from leade/start of rifling to muzzle. In keeping with the fact that ignition starts in the case and hence the case forms part of the ‘barrel’. So it seems to me that case length shouldn’t matter in this specific issue?? Of course case capacity is another matter entirely. Not sure if I’ve made my point clearly?

Greetings HandH,
Yes you made your point clearly. Most barrels are measured to the bolt face for convenience. If you think of a projectile as a rocket sitting on a ramp it might help. The rocket motor provided an amount of thrust similar to the pressure behind the projectile. thrust/ pressure is the same the rocket will accelerate at the same rate and achieve the same velocity at the same distance from the start. If we now go back to our projectile the barrel is our launch ramp and the length of travel of the projectile determines the velocity provided everything else is the same. The devil is in those last five words. With John and Charlie's test the length of the barrel to the base of projectile was the same and the velocities with some loads were near identical. With other loads they were not. In practical terms it matters little how barrels are measured as the difference in velocity is miniscule. Still something for the anal to ponder over though.
Regards Grandpamac.

My understanding is that there are four elements to the short fatty case design that improve accuracy. If you look at how winning benchrest cases have influenced modern cartridge design, then it’s probably fair to say that the long, tapered cartridge designs of yesteryear are done and dusted.

1. Sharp shoulder angle (more positive headspacing)
2. Very little taper (co-axial alignment to the bore)
3. Longer neck length (improved concentricity)
4. Short fat case (powder burn efficiency & uniformity)

Plus of course a lot of the short fat cases are able to shoot long for calibre, high BC bullets, with chamber dimensions allowing far longer extruding bullet length than what went before.

Grandpamac.

the are all sweet. pick a calibre and shoot. The short fat ones seem to be popular in bench rest ect. br dasher 284 saum wsm. As @Flyblown said even burn ect.

the trebly has had name as being better than the 223 for accuracy....the longer neck COULD be answer....
