Has anyone tried this powder? I just saw it on Hodgdons website and think it might be worth a try.
-
Here is what I know. I haven't used it yet but will real soon. Still working up a load for it.
Hodgdon's new Hybrid 100V propellant combines the chemistry of a spherical powder with the geometry of an extruded propellant. According to the company, Hybrid 100V is ideal for use in calibers that fit H4350, and it delivers velocities not seen before in many popular cartridges, such as 3310 fps for a 150-grain bullet in the .300 Wby. Mag. Its unique small-grain, semispherical/semiextruded shape allows it to flow smoothly through a powder measure, thereby improving charge weight consistency and load density.

It does sound good and I intend to find some and try it in my 300wsm. Hodgdon doesn't put it in the "Extreme" powder class. Any idea about it's temperature sensitivity?
-
Killbilly, I'm curious how you are working up a load with the powder if you haven't tried it yet?
-
real easy, I am studying what gr. bullet I will use, what muzzle velocity I want, and which of the calibers I own I will try it on. That's how..... you looking for an argument friend... :chuckle: :chuckle: :chuckle:

No. Just an honest question.

And I knew that, just a bad attempt at some humor

I picked up a bottle of Hybrid 100V today and will be testing it shortly. I'll let you know what I find out.
-
Another powder that would be worth a look at is the Ramshot hunter. It seems to be about the same burn rate as the Hodgdon Hybrid 100V, and the load data for the cartridges I checked seem to be nearly identical to the 100V. I believe the Ramshot powders are not very temperature sensitive.

Today I tested several bullet weights including 150's, 165's, 180's and 220 grain with the Hybrid 100V powder in my 300wsm. I am impressed with the results in velocities. I got the highest chrono'd velocities of any powder I've tested with all of these bullets. Two of the groups were at 1" and the other two were in the 2" splits. It's been awhile since I've done much shooting and even with shooting rest, I'm probably partly to blame for the bigger groups. I'll be trying different bullets in the future to tighten up those groups. I stayed within the loading data limits and found no pressure signs. Hodgdon claims higher velocities with this powder and I found it to be true but the differences were only 50-100 fps better than previously tested powders. Anyway, I'll be testing it for temperatures to see if it's finicky between hot and cold. I refridgerate one set of matching loads and leave the other set at outside temperature on the front porch on a day above 70 degrees before I shoot them. Chronographs tell the story from there. Generally if my velocities vary much, so do my groups. Places I hunt can be frozen in the morning and 65-70 degrees in the afternoon so that is quite a split to deal with. Maybe just splitting hairs with all of this but that is what reloading is all about.
I have also tested Ramshot Big Game and Magnum powders and wasn't impressed with the pressures, velocities and barrel fouling. I stayed within published load values and found high pressures and low velocities with those powders, not to mention it was filthy. I'm sure other people may have had good experiences with Ramshot powders, but that was my personal experience. To each his own.
