H4350 in a 280AI.

[Russ-T]

H4350 is on the fast side for 280 ai. You will get 100% burn at about 90% case fill with standard sammi COAL.
Should be around 3k fps

H 4350 is faster than H4831. Both are temp stable powders. Most of the IMR powder aren't temp stable powders. Beware!

Look for the ones that include "Made in Australia" at the base of the label.

The Hodgdon powders that are largely insensative to temperature are the ADI Aussie powders distributed by Hodgdon.

The Made in Oz is printed on the lower colored band on the label.

So what's the difference if any? I know that H powders are largely temp insensative. I switch to them in the late 90's.

Only the Australian powders. Hodgdon does not make powders, they never did. They badge and market powders from several sources, some of which are recent purchases for them, but the ADI powders are never for sale. ADI stands for Australian Defence Industries and is owned and financed by the Australian Government.

Selling product to an ally nation helps offset the costs of manufacturing and maintains independence in supply for the military there.

I see now. I didn't understand what was going on.
THANKS!
