How Temperature Sensitive is H414 Compared to IMR 4350

[willymike]

For you H414 and IMR 4350 shooters. Have you discovered a large degree of temperature sensitivity between H414 and IMR 4350?

I've been loading both in 30-06, pushing 165gr bullets and have had great results with both. I mostly load IMR 4350, but also use H414 as my backup powder. I've not seen a great degree of sensitivity with 4350, but have not shot the H414 enough to make a determination as to the comparison during temperature extremes.

What say y'all H414 reloaders?

I to load both those powders in `06, both give AWESOME results like you stated. I haven't noticed any temp sensitivity with either.

Ball powders are known for often showing temprature problems. Magnum primers were originally developed because of the trouble of getting reliable ignition in cold temps with them. H414 is the same powder as WW760, just repackaged and sold under the Hodgdon name and is most likely not as stable in wide temprature swings as IMR4350, and definatly isn`t as stable as the Hodgdon flavor of 4350.

LOVE H414. I have shot identical loads in 95 degree weather and 10 degree weather. Shoots to nearly the same POA. About 1/2" low on the cold days. Not very sensitive to temp at all IMO.

Thanks, guys!

Just looking for some users of both that have actually noticed or quantified through load work up that there may be a real difference in the two powders when temperatures are taken into account.

I'm certain there is probably a difference, but just don't know how big it matters in the real world.

Thanks to t2e for the specific help here. I'm making the assumptioin that 1/2" low is at 100 yards? Anyway, that's good information to know.

If anyone else out there wants to weigh in on this, I'd be most appreciative.
