Need a favour from someone with quickload please. The following is the load data and i am interested in the pressure difference and predicted difference in velocity

Load 1
Calibre: 458 Lott
Powder: S355 (Somchem)
Weight: 77 grains
Bullet: 500 grain Hornady DGS
Primer: CCI 250
Case:Hornady

Load 2
Calibre: 458 Lott
Powder: S335 (Somchem)
Weight: 80 grains
Bullet: 500 grain Hornady DGS
Primer: CCI 250
Case: Hornady

Thanks

Although QL does have problems predicting the internal ballistics for straight cases like the Lott, 80 grains is pretty Hot, you may want to think about that one for a while.

By no means take this as a fact without research and testing but S 321 produces about the same energy with less pressure.

Just one more thought.

On the QL graph:

Yellow means you are in a comfortable pressure zone.

Purple means you’re tickling the dragon’s tail.

Red means you’re flirting with disaster.

Mick thank you very, very much! Could you please run it with S355 as well?

Thanks

I feel more comfortable with S 355.
