Thread: Short fatties vs long slender ones...

I thought the short and fat is where its at was more to do with consistant powder ignition/burn for better accuracy?

Pretty much every modern popular chambering for competition shooting has this design.

Agreed. The short powder column centers more of the powder closer to the primer flash for potentially more efficient ignition and burning. Apparently.

Yeah PPC inspired designs (short n fat), are indeed more accurate than longer cases holding similar amounts of powder due to less velocity spread (SD over Chrono). But it generally takes a very accurate rifle to prove it out and the short fatties give no increase in velocity over long and slender.

or longer ranges (much longer) where velocity spread has a bigger effect.

Yep, and drag out the theories on gas turbulence and try and understand them. Although shoulder design probably has more influence here.
And then there is brass flow to theorise on as well.

So velocity only may be a one dimensional answer.

The original question re barrel length probably wasn't answered.
Nope, I don't have the answer.

No sure why the writer of the article chose 300 H & H except of course for comparable capacity with the WSM.
THE 300 H & H certainly meets the long and thin criteria but it's design was such to allow early days loading of cordite strands.

Ah, I get it, the good Olde days and nostalgia (usually cockeyed due to brain fade).

I thought it was supposed to be a clinical comparison not an old versus new theme.
