Powder for a 357 at 100 yards?

[DedIdick]

You say you weren't happy with 8 gns of Unique??? 6.5 gns of Unique works OK in my 24" barreled 357.

Very interesting!

With the same type Marlin, and using 8grs Unique with a copper washed 159gr head with CCI small pistol primers, Starline cases, my rounds are approximately 2 to 3 inches low at 100 yards.

I wonder why the difference? Do you pack the cases at all?

That's what the rear sight is for.
Is the grouping OK, that's the important bit!

Due to age, eye sight not good enough for using rifle sights I'm afraid, so a scope is used.

Would still be interested in other powders that forum members use for this distance.

I use 6.8 grains of Unique with a 158gr cast bullet (roundnose and semi wadcutter) at 100 yards.

I use 7.2 grains of unique with a 158gr copper jacketed hollow point bulllet for foxes. Tested at 100 yards and group ok.

If the groups are good but is shooting low then adjust your sights.

I used to use Blue Dot in a Marlin
N320 I used for low target loads

Although Ive yet to try this, Ive been recommended RS30 for .357 with powder charges around 12.5gr - 16gr (158gr Heads).
