Can anyone direct me to a ballistics calculator that incorporates barrel length (If there is one)

I doubt any will, barrel length has zero effect on the bullet ballistically.

I know a bit less than two tenths of Jack all, but dosnt a longer barrel give you a higher muzzle velocity?
As you can see on the link below, they've supplied the data for a 10.5 inch barrel right up to a 24 inch barrel.

I think you might be better off asking your real underlying question rather than what appears to be part of a thought experiment.
There is nothing new under the sun and out of the clutter of answers you are likely get you might be able to glean the appropriate understanding you are seeking.

I'm trying to determine the muzzle velocity of the S&B 30/30 150 grain projectile. The muzzle velocity supplied on the website is out of a 24 inch barrel, I have a 20 inch barrel.

Or is this a program that helps with knowing start & max load densities...
But to repeat everyone else, you'll only "know" by using a chrono...
Even the above example would be reliant on the actual known click value of the scope--meaning if for every 1moa you dial, if the scope dials 1.2 moa, you'll get a very wrong answer...but it still relies on an initial velocity approximation anyway...(but i like the idea... ).

My Win94 has a 20" barrel, I'll go into town tomorrow and grab a box of S&B 150gn and chrono it in mine.

Bladeracer, all good mate, you don't have to. You're a gentleman. Thank you.

It's a handy excuse to do some shooting with the '94, and I like shooting

Inside the box lid is stamped "98/3" - surely this stuff was not made 22 years ago?
Velocity is specified at 728mps or 2388fps.
Five rounds gave me a mean of 2274fps, ES of 69fps, SD of 24fps.
I fired a five-round group of subsonic 150gn Berry's first at 1050fps, grouped at 55mm on zero.
I held low for the S&B and grouped 38mm, just holding "somewhere on the bottom of the board in the grass", very nice. Group is about 400mm higher than my subsonics at 50m, but directly above - nice to know. The S&B is zeroed at around 500m for me
Then, for giggles, I fired one at a 410UB at 50m. 8mm steel web and it punched an impressive hole through it.
Seems like good ammo.

Such a comprehensive analysis, bloody awesome!
22 years ago? What's going on there?
I feel good about this round now.
Looks like you had fun doing it, but I'll say thanks anyway...Thanks bladeracer.

I would guess that you want to know the velocity for the same reasons anybody else would, including myself
Have a look in the lid of your own boxes, I'm curious what else the stamp could refer to.

Wow! That's pretty crazy
I guess they did a massive run of .30-30 ammo back then.
