New 357 barrel strangeness

[Pipian]

Rebarreld my rifle with a Kreiger 357 barrel with a 14 twist. I’m beginning to work up a load, but as time as to what weight and size lead Boolits, I might try first. I surmise that I did my break-in with a box of 125s and they spiral out for being too light. Any any good suggestions?

I would start at 160 or more. You may find 180-200 about right.

What should I size them at?

Start with a SWC 158 grain and sizes to .358.

1-14 is fast for a 357 magnum rifle most barrels are 1-16 or 1-20.

Your rifle may like 140 to 170 grain bullets.

Unique is my go to powder for my 357 magnum rifles.
