What Twist Rate to Use (300-Grain Bullets, .444 Marlin, Custom-Built
Sniper308
300-grain jacketed bullets. What's the best twist I should order for
the barrel?
Thanks.

the 300 gr or heavier bullets - though is just fine for 240gr or less.
Of note; th 45-70 runs 1:18" or 1:20", and that'll stabilize up
through 400 gr. The 458 WM or 416's tend to carry 1:14".

Marlin hasn't made that twist for a couple of years now. I forget
what the new twist is, I think 1-24, and IIRC the Winchester Big
Bore is 1-20".
Marlin will rebarrel an old 444 for about $135 with a barrel using the
new twist rate and "Ballard rifling".

I'd normally agree with this theory, except for the fact that a great
many people get good accuracy out of the 300-grain bullets in the
Marlin Factory barrel with 38" twist. Even Speer mentions this
'theory', noting that their best accuracy with the test .444 was with
the 300-grain bullet. Hornady recommends their 300-grainer for the
444, and Sierra even recommends their 300-grain bullet in a .44
Magnum with 38" twist rate. Rick Jameson has often written of his
success with 300-grain bulets in Marlins. So it is probably worth a
try.
Remember that Hornady created their 265-grain bullet especially for
the .444, and Remington factory loaded a 265-er too. If you want a
heavy bullet but don't like the idea of a 300 grainer, try that one.
That said, if I were building a custom rifle in .444, I'd go with a
faster twist too.

for any of the 300 grain slugs on the market. I know, I have tried them
all, and have been shooting 300 grain slugs for the past 20 years
(original Barnes).
If you are using a P-14 action, I would go with a 1-24 (as I did!) and
have the throat cut long to allow the use of 350 and 400 grain slugs.
If you make some dummy rounds with 400 grainers that fit the mag, then
use a throater to cut the throat to fit the dummy cartridge. It is
quite interesting what you can do with a 400 grain slug using a P-14
action.
My two cents,

i made a p14 1:38 twist, super lightweight rifle.
1 hole groups @ 100 yds 300gn bullets
but have settled on 285 gn 4 ogive pointy ones (self swaged)
for my regular hunting load (i wanted to flatten the 'rainbow'
trajectory a little !!!)
