Anybody out there using H414 with cast in any of the 30's. If so, your thoughts and opinions please!
Thanks in advance to any who respond to this thread.

H414 is a slow burning ball powder that at lower cast bullet pressures can be hard to ignite, especially in larger cases (.308W capacity and above) with light to medium weight cast bullets. In smaller cases with heavy for caliber bullets (30-30 with 180+ gr cast bullets) it can work very well with top end loads (pretty much 100% loading density).

I use it for jacketed loads in my .338 WM. As Larry said, it's a slow burner and probably not a good choice for cast loads. In case you didn't know, it's the same powder as WW 760.

Favorite powder for heavy j-words in my 22/250

Concur, just wondering!

Like Larry said, not the best choice for larger cases, lighter boolits, and modest velocities. I'm not sure what pressure it takes to make it burn clean, but I'm thinking over 35K PSI. Someone might chime in with better information. It's a fantastic powder for .308 and smaller with heavies, or smaller calibers. It's absolutely wonderful for 7mm-08, .260 Remington, 6.5x55, etc. with medium weight (130-150 grain) boolits at the top end, the large, short cases and small bore diameter calls for a slower powder sometimes. It can be sketchy in the .30-30 unless going full-tilt with 170+ weight boolits, and I prefer 748, Ball C (2), and H335, or Reloder7 and 4198 for "midrange" loadings in the small/medium cases.

Not so much with cast but I use H-414 for a specific application.
If working up a load with IMR 4350 but run out of case volume before max pressure I go to H-414 to gain powder volume. It is a ball powder with the burn rate of IMR 4350 or any of the 4350s. I prefer extruded powder for ignition charectoristics but when I cant get quite enough 4350 in a case 414 enables a few more grains staying with the same burn rate.

It's one of my favorites. I use it in a lot of Jacketed loads, 300WSM, 22/250, 30/06., 260, 7/08, I use 180 grain RCBS cast with it in 30/30.
