SIG 357 with Cast Bullets

[Ganderite]

I have a Glock 31C and want to load lead bullets for accuracy and cheap plinking.

The only bullets that I have found on my shelf that are short enough in the nose section to load are the DRG 130gr FP. These are sized 359 for 38 Spl, but seem to fit the case ok. I will try 3.0 to 4.2 of TiterGroup.

I see Berry makes a plated bullet for the SIG 357. Anyone else?

The lee 120gr TC looks like it would work good, http://leeprecision.com/mold-6-cav-356-120-tc.html

Titegroup is too fast for 357SIG. H110 is better. Also the SIG round is awful fast for lead.

If I want full power ammo I would load a jacketed bullet and Something like H110. BUT "I want to load lead bullets for accuracy and cheap plinking."

I find cast bullets are accurate and cheap and a fast powder like 231 or TG works well. Velocity will be 800 to 1000 fps.

Update: Just tried the 3.3 gr of TG. Did not cycle the action. 3.6 did cycle, but just barely. I will load a batch of 3.7 and 4.0 and 4.3 and test for accuracy.

I loaded 3.7, 4.0, 4.3 & 4.6 Sized 40 brass down to 357.

Will Chrony tomorrow.

Velocity results:

3.7 gr TG 900 fps (barely ejected)
4.0 920
4.3 1020
4.6 1050

Next will test for accuracy.
