357 MO Bullet 180g Pug Load?

[clelaj]

Spotted the 180g flat point lead bullet at MO Bullet in 358 diameter. Anyone load this? Thinking of something under 13 grain 2400 powder as a upper limit. Based this on the 180g fitting deeper in case than my 158g lswc by 10%. So reduce 158g load by 10%

I load their moly coated version on the 180gr pug for my sons deer load out of his 357 HR rifle. I experimented with a few powders and ultimately went with 4227. Shoots a nice clover leaf pattern @ 50 yards running right at 1250fps just the right distance for hunting his stand.

Uh.....no
Pressure curves are NOT linear.
You can't extrapolate.

Lyman Cast #4 lists the Saeco 180gr w/ 2400. If the profile is similar, that would be a fair place to start

I load them for Bowling Pins, but I'm using Power Pistol.

Don't go interpolating your powder charges and instead stick to actual data.
According to Loaddata.com, 180 grain cast bullets using 2400 should have a starting powder charge of 8.0 grains and 12.0 grains for maximum charge level.
