Reloading data discrepancies

[Jester560]

Im getting into loadi g .357 Magnum. Been doing my due diligence on researching loads and powders. Decided to go qith VV N110 powder.
The tricky part is the wide window in load data. Using 158gr XTPs, Hornady data reaches max at 13.1gr of N110. VV data starts at 13.5 and reaches max at 16.3gr. I am at 15.0gr with zero pressure and almost 1100fps out of a 2.5" barrel.

check against case trim length and coal...............i wonder about these same things when cross checking data............i don't own or have ever reloaded for that cartridge, so i'm not much help with that cartridge................the only vv pistol powder i've used is 3n37, but have and still use h110 which is supposed to be the same as ww296. does it list 3n38?

 

[Jester560]

Yes it does

I prefer the case fill of N110. Ive used 3n38 but itvwas for 9mm major loads.

Depends entirely on who wrote the data. Bullet companies write data for their bullets. Powder companies write data for their powder. They may use different methods.
That's why they always say start at the bottom and slowly work you way up while watching for pressure signs.

Yes Sir, i always do. I am in the middle of the VV data safely.

i have not loaded for .357 mag yet, and might not ever, for target practice, i prefer .38 special.

but i do use Tite Group, and here is what the powder site (Hodgdon) says.....

You can only trust your loads. The manuals are for starting references. You have to do load work up
