Solo 1250 vs Solo 1000 for major .40:

[JimmyZip]

It's 1.20. 1.135 is factory OAL. a 40 S&W round with a 180 jacketed bullet with 4.9gr of Solo 1000 at 1.12 OAL would be at the very least stout. More than likely, it would be too stout and bad ju-ju on a small scale would happen.

My favorite 40 cal load is a 180 BBI, 4.7gr of Solo 1000, 1.185 oal, mixed brass and Wolf SRP's.

I'm loading them to 1.143-1.150. That is the variance I get on my SDB. I show no adverse signs of pressure on my brass. I can't recall what they chrono at I would have to dig through my mess, but I recall they made pf by about three? This is out of a CZ TS with a barrel just under 5". (Most say it is a 5 but it is just under.) Seems soft too. I really like this load.
