Thread: W760

Does anybody use this powder? Any issues like the Reloader series has with temp changes? Or any other issues?

I've never noticed anything wrong with it.

Was using it in the .243, preferred a the magnum primer to get more consistant fps. Never really tested for temp sensitivity as I developed the load mid summer and rarely shot it over 200m. Probably worth doing a test on that issue at your end of the country though.

I've always liked it. Worst thing is that it is quite dirty. It's very close to 2209 for burn rate.
Has worked well for me in 7/08, especially with 120 grn Sierra and Nosler. Also 22.250 and .243.

Friend of mine uses it in his .270 loads. Very consistent over the chrony and very accurate. Have contemplated trying it in .243, because of how easy it would meter, but have always read how temp sensitive Win powder is.

Do you have other side effects when using mag primers in general? So for the same powder charge there isn't an increase in pressure? might try it as my vel. spread is crazy high.

Hmm that is the first I have read on temp sensitivity, maybe I should read wider...

Isn,t it H414, I,ve ordered some and Wayne Chapman told me it,s H 414 which is temperature sensitive.

swapping to the mag primers the av fps went up about 70fps and variation down to about 30fps. I had no pressure issues but I don't load go near max loads.

It is often said on overseas forums that 760 is temp sensitive, haven't down enough testing to see for myself and really our temp variations aren't that big compared to central USA etc.

Used it in my swed and 300wsm. Have loads in the AI with it too but yet to test them. Hopefully my suppressor gets here by this weekend and I'll try it then

I pretty much use it solely now great powder
if you cant get w760 H414 is exactly the same all the load data is 100% same stated pressures and everything

Im using H414 in my 260, and it gets good velocity and accuracy. Haven't had enough experience with it yet to comment on temp sensitivity tho.

H414 and W760 are as pointed out the same, nowadays. I am not sure if 760 morphed into H414 or the other way round.
However, older batches of 760 may not be exactly the same as the latest 760/H414 brews.
And yes, they/it has a reputation for being temp sensitive. I have never experienced any issues though and I run one load using 760 that is reasonably well up there. I also don't leave my ammo lying around frying in the sun either.
