In the next few days I plan on going over to my friends shop to cut a few molds
The question I have is about the Hollow Point Mold I plan on cutting for the 357 Mag
I am planning on a .360 dia 150 to 160 gr semi wadcutter mold with a adjustable hollow point stem
What I want to do is use these bullets to hunt groundhogs out to (maybe) 100 yards with a Marlin 357 Mag rifle with as hot of reloads as I can get to group well
Most likely out to 75 yards will be the Max for most of the "Long" shots
But I want the hollow point to help anchor the groundhog
Also I want the hollow point to help control how much the bullet will keep going after passing through the groundhog
So I want the bullet to expand as much as possible
I will be casting these bullets out of a soft range lead
Mostly made of jacketed bullets and 22 LR bullets
But there is always some hard cast bullets in the mix
So my question
How much do I have to leave between the base of the bullet and the bottom of the hollow point with a plain base cast bullet ?
Same question of the amount I have to leave between the base of the bullet and the bottom of the hollow point with a Gator Gas Check on a cast bullet ?
I am asking as I don't want to blow the lead from the base of the bullet through the hollow point and leave a "Tube" of lead in the barrel
As that would make "Cleaning" out any "Leading" a rotten job
Thanks
