how come you dont hear of anybody doing a 21, 23, 25, etc inch barrel? seems all you hear about are even numbers. 20, 22.... is it just tradition? what?

Re: barrel length question
We arent smart enough to count between even numbers. I know there is some famous smith that swears by 21.75" as optimal length

Re: barrel length question
I do.
Ive just gotten started in this game but the barrels I've turned so far have been odds as well as evens.
I have a 21" on my 243, and will be going to a 23" I think
...rebarreling it in 3 weeks.
We use quickload to get an idea of ideal barrel length for a given load and rifle barrel. For example, my buddies 308, with a 26" tube, only gets 100fps more than the same load in the same rifle cut down to 20". Quickload agreed with our real life findings. So in that case, I wouldnt go longer than 20"
For my 243, I dont get much more velocity from my load past 23". It still goes up obviously, but at a lesser rate than 20" to 23". So, I consider 23" to be ideal.
I like compact rifles, and dont mind giving up a few fps to save a few inches. So I try to decide on barrel lengths in a practical way. Even if it lands me on a 21", 23", 25", or 27" barrel.

What smith is that?
Swearing by one length for everything is silly. Kinda like saying which crown angle is most accurate.
There are a ton of variables.

Re: barrel length question
The guy that done mine made it 251/4 for some reason.I don`t know why but it sure shoots!Whatever works I guess.

Re: barrel length question
I could be wrong, and often am, but I think that 21.75" came from the guys that were shooting in the warehouse in Houston. I believe they were shooting 6mm BR. They spent a lot of time doing experiments and that was the number that they came up with.

Re: barrel length question
LOL, These old codgers settled on 21 3/4" ,they were shooting 1,200 yd bench-rest.

Winchester had a few 25" barrels for a few cals. <64 ,mod 70...

Re: barrel length question
LOL, I read that some time ago and never for a second thought it was completely non-fiction. Ever since, I see the magic 21.75" referred to as if it was based on methodology as opposed to Hemingway.
For quite a while I hemmed and hawed about having my 26" varmint trimmed to 23", but am now glad I made it 22". It's still a beast, and I can't believe I hauled 26" up and down mountainsides. Standardization is a Good Thing, especially when you are looking for ballistic data or resale value.
