Almost full powder burn?

[kenbro]

Hi,
Can anyone with the tools tell me the minimum barrel length that will burn 95% of a powder charge, please.
Tikka T3V.
.222 Rem.
52 grain bullet. Also, if poss. 40 grain bullet.
Powder: Vhit N120 x 19 Grains.
Case water capacity: 28 grains, no meniscus.
Tia; Ken.

Which 52gr, and 40gr bullet ? Flat base or boat tail ?

What length are you trying to get down to, and can you use another powder ?

If you've got a laptop or std pc download Gordon's reloading tool. It's similar to quickload. It's very good and easy to use, it'll show you burn percentage.

Or P-Max internal ballistics which is free.

Can’t help with the question but for info my .222 Remmy loves 40 and 50gns bullets but would not stabilise the 52gns Vmax.

Hi,
Thinking 18” or even 16”
I could go faster with Vhit N110, I think.
Flat base bullets.
Thanks, Ken.

Hmmm,
My T3 shoots the 55 grain BergerFB TARGET bullets more accurately than the 52sand they are exceptional.Ken.

Different bullets to what I use but this gives a good (Or bad!) idea.
Thanks BB.

Don’t use a P or Tablet!
Thanks, Ken.

Funny enough my Remmy loves 55 gns Sierra Gamekings - lethal on Roe.

This from P-Max.
Look very different to Bavarianbrits post.
Ken.

 

[kenbro]

Would some look at at the calcs from P-Max and how they differ from what Bavarianbrit posted re percentages of powder burned in shorter barrels?
Thanks, Ken.

Good idea Kenbro, except the program he has used (QL?) asks for case volume H2o. P-Max uses a different method in that it uses Case Capacity H2o with bullet seated. So wouldn't give a like for like answer in his case - not a pun

Ha, my bad, I hadn’t picked up on the bullet seated part.
Thanks much for the lesson.

Try n133 with 52gr I was getting 3540 out of 22”

Vhit data says N133 x 52 x 23 inch barrel, compressed load = 3264.
Thanks, Ken.

You might get cleaner burn by upping the load and thus pressure.

I was using 28.6gr with 52gr ELD-M

Are we talking the same cartridge here, 222?
