223 Rem barrel length velocity test - 12.5 inch vs 16.1 vs 20 inch

[351 power]

Great info. I was thinking about powders having an affect. Reloading especially for the barrel length makes sense. Never having a barrel shorter than 18" I was wondering what the advantage is going shorter than say 16".

Well this is interesting.

All depends what you want to do with it really.

Many say “look at that only losing a couple hundred FPS in the short barrel”. I can’t help but notice the 12.5” turns it into a loud .22 Ackley Hornet. Especially on the receiving end, 100fps makes a difference in bullet performance, 200fps is the difference between cartridge classes, and 300fps puts them in different categories completely.

19” is my cutoff for a round that rely’s on velocity as much as the .224s to do work.

A long gun is a long gun for a reason. But we like to tinker.

Surprised at the loss from 20 to 16, not much between 16 and 12.

Indeed. I just ordered a 9.5" BCL Bronco Howitzer just to mess with

Can't shoot 73gr ELDm in a 22 Ackley Hornet!

There is that! Same reason I put 5.6x50 powder behind the 80grs out of a 19”.

Well this is interesting.

So basically, longer is faster and faster is more accurate at range.

But you won’t be allowed to hunt with it.

What that says is that velocity helps with hits.
