So the results are predicated on a 16.0" barrel length?

 

[Phil Rizzo]

It became a .308 Win AI eh?

 

[darrindlh]

Thank you for your replies. My barrel is 24 inches. Would that change?

It wouldn't change the pressure but would most certainly change the velocity.

What do you think I could expect

 

[Berrnard]

What do you think I could expect

+250ish fps

 

[darrindlh]

+250ish fps

Thank you.

H-4831 start 77gr you might see pressure at 80 - 82 and you might see 3100fps.
Be careful.
H-1000 is a little better.
Hope this helps.

Thank you so much. Not to switch topics onlol but do ya'll think N565 would work better? I believe its closest to h1000

Just a side note. With 180 grn bullets I had good luck with IMR powders (IMR4350 and IMR 7828), bit with Large Rifle (NOT Magnum) primers. With 200 grn I had good luck with RL22 and Fed GM215.

Thank you asd9055 Im with you, I know imr 7828 is amazing with 300 weatherby, but I cannot find any. So im out of luck. Im trying to find the next best

As @Berrnard posted 250 is a good ball park #
