Velocity Question

[wmdurway]

Good morning all,

I’m new to muzzleloader hunting and have a (hopefully) quick question on velocity.

I am shooting a Traditions muzzleloader using 250gr Barnes TEZ over 100 grs. (Volume) of Triple 7 powder. I marked my ramrod at 2.5” to maintain a consistent loading.

Everything I’m reading shows I should be in the 1800-2000 fps range. But when I chronographed it, I’m around 1560.

It’s very accurate and the velocities are relatively consistent. But it’s very slow.

Any ideas? Am I doing something wrong?

Thank you,
Will

How long is your barrel compared with the test barrel?

Edit - Google searching suggests to me that your estimated velocities are rather high.

Thanks for the info. It’s 26 inches to the breach plug.

Should I keep bumping up the charge weight to 110 and 120 grains to see what speeds I get?

I am not going to advise what you should do. I know some people who shoot some large charges of 777, but the inline my mentor gave me last year shoots well to 100 yards with 100-grains of 777 and a saboted Barnes bullet.

You should be closer to 1950 fps assuming it’s a .50 and you’re shootinv 2F 777. When you say you marked your ramrod at 2.5” - what are you saying? They you marked it at loaded?

You’re seating the bullet/sabot firmly on the powder? And what cap/primer are you using?

Is your chrono messed up?
