Huge difference in 357 mag load data

I'd do four steps for the first ladder: 15.1, 15.4, 15.7, & 16.

Yes, look at it this way. If you start low and work up what is the harm? All guns, reloading supplies, and powder has some variation - even your reloading. So just work up and look for pressure signs along the way.

[devster55]

Yeah that was the plan just wanted to get a second opinion. Thanks guys.

In 8 yrs of reloading, I've found thst starting at the minimum load is usually a waste of time and components.

Not very accurate, some guns don't cycle (revolvers exempt!), and the overall experience is like kissing your sister-not very enjoyable or productive.

I plan on just doing 10 of each up to max. I’ll be shooting these in a Taurus snubnose 357. They are mainly for fun and a big flame. My friend who is also loading the ammo with be shooting them through his ruger Blackhawk which I know will have no problem with the loads. I’m just iffy on the Taurus. It’s not as built like a tank as his Blackhawk.

Speer data start 13.9 - 15.5 max.

H110 is a relatively slow burner on the pistol powder spectrum. In the snubby taurus you won't get max pressures in these load ranges. Pobably the most discernable difference between load increments will be the size and length of the flame front out of the barrel as a lot of powder is going to be blown out the muzzle as it burns.

Doesn't look Yuge to me. 1 gr?

Different labs, different powder lots, different primers (and lots), different bullets..........

Common wisdom is H110 can be dangerous when downloaded. Personally, I think that's poppycock invented as a solution to other problems.

Normally with pistol powders most sources are close. Just have never seen a difference like this. I also read about the h110 being downloaded and that was my concern. Gonna load them up tonight.

H110 used to say not to download more than 5%. W296 used to say 10% IIRC.

Note the H data you posted is an appx 10% spread. Start at the bottom and watch for for fps and pressure signs. I can flatten 357 primers with book data, so do pay attention.

I use Hodgdon data and still have all my fingers.

If you like flames, try some LilGun.

I'm not looking at a bunch of data at the moment, but I still say it doesn't seem yuge to me. Not with a slow burning powder requiring in the 16 gr. range.

There's also a difference in era. Newer data tend to be more conservative.

I run about 15.5 gr of h110. Ymmv. 586 and 686 both 6 inch barrels.
And yes you will get flames.
