I loaded up some in my 7-08. It's -20 below here. You guys think I'll run into problems when it's 70+ this summer. I'll start lower then and work up again. I was just wondering what your experience has been so I know if I need to shoot up what I have before it gets warm. Don't want to make a mistake and grab the wrong load.
Want To Buy;
Form die for a 7mm Mashburn Super.
.284 Hornady AMax 162gr.
.224 Hornady AMax 75gr.
22-250 bushing die
Bushing die that will work with the 7mm Mashburn Super

Load what you need up until then... or disassemble what you don't shoot between now and then.... or load 5% below max, you should be safe.....

I do it the other way round. I load my stuff for 50-80 degrees, and then shoot it in colder weather too. I have found H414 to work very well with 168 gr TSX in my 30-06. Also with 140 gr Sierra BTSP in my 6.5 Swede.
Very versatile powder. And it is Hodgdon Xtreme, isn't it?

I believe h414 is the spherical equalivant of h4350

Nope, H414 is not one of the Extreme powders.

It's "extreme" alright. Extremely sensitive to temperature change.

I never had much luck with it. I tried it in several cartridges, but I had ignition problems and pressure spikes with it. And yes, I did try different primers and bullets of comparable weight from different manufacturers. No joy here.
I would do what Keith suggests: Work up a load in the warm weather and use it year round. I have half a pound that I use for testing every once in a while, but I prefer one of the 4350s. I don't care for it.

Sorry for the bad info on H414 and cold insensitivity. I've never encountered a problem with minute of deer or moose accuracy and lethality with it. I load and shoot mostly around 65-75 degrees for practice, and my hunting is usually in the 50s and under as low as 35 below. Killed stuff just fine regardless of temperatures. My shots are generally not more than 250 yards.
I think that H414 and Win 760 are twins.

H414 produced the best accuracy in both my 30.06 and 7mm-08. It beat out favorites like Benchmark, Varget, H4350, H4895, Reloader 22. I like H414 when it works. Some say you need a Magnum primer but using standard Winchester Large Rifle works in the cold of Nebraska winters during deer season. My picky 7mm-08 shoots a max load of H414 and 140 TTSX into small clusters.

Excellent .22-250 and .220 Swift powder. I don't know about temperature sensitivity, but my maximum loads were always a couple, maybe three grains less than what the books would list.
I haven't used any H414 in a while, having found other powders that do as well from both accuracy and velocity standpoints.
One of the first times I used H414 years ago, I was working up .250 Savage loads. There was a significant discrepancy in book figures and what I was able to do attain with my rifle.
Based on my limited experience, I would guess there may have been considerable variance from one powder lot to another. That may not be true with current lots.

I tried it and didn't have real good luck with it, so I stayed with the 4350s. I ended up pouring the rest out in the yard as fertilizer. It is so temperature sensitive that the grass quits growing in the winter..

I have a jug labeled "Made to U.S. Military Specs." and 55 grains of it with a 180 gr. Hornady SP produces 2553 fps. When loading the same weight with another lot I get 2700 fps.

Ain't no flies on either of the 4350s either, and I've burned more of that than H414, but with the 168 TSX in the 06, it's the bomb for me. If I had to go back to IMR4350, it wouldn't singe my tail feathers one bit. I still load a bunch of I4350 with 165 gr BTSP Hornady's for a couple buddies, and one of them thinks they are magic moose killers. With him doing the shooting, they are!

I've always heard people talk about how great H414 is in the .260 Rem, .243 Win, .30-06, etc, but I've played with it some and just hated it. Didn't get good accuracy with any combination. The 4350s are much more to my liking. But - good luck!

H-414 shoots well in my 7x57 using 120's-154's. Haven't tried any heavier bullets yet.

I think that H414 and Win 760 are twins.
Not really twins but the same powder in two different packages. A great powder for certain applications, it is an old school ball powder that is temp sensitive but nothing like H380 or BL-C(2). It is also one of the dirtier burning powders. On the up-side sometimes H414 (W760) can give velocities and accuracy that is tough to match, I wont use anything else in my 220swift's

The 4350s are much more to my liking. But - good luck! It seems to me that H414, just as other ball/spherical types tend to be, is a bit pressure sensitive - more so than the extruders tend to be anyway. It burns well when the pressures are well up; not so much, perhaps, when you back off the throttle.
