Is H4831 gunpowder okay to use in a .270 with a 130 grain boattail spitzer bullet?

Question

I'm using a classic lee loader and I'm putting in about 53 grains (wt.) of powder. I intend to use these both for hunting and target shooting.

Answer 1

Yes H4831 is a good powder for use in the .270 Winchester and has been for decades. Based on published data, this appears to be a very reasonable load, but what really matters is how it performs in your rifle.
I'm sure you know this, but don't confuse H4831 and MR 4831-the two are not interchangeable; IMR 4831 has a faster burn rate.

Answer 2

I'd imagine that's getting you under 2800 fps, and you could probably push past 2900, but we don't know what bullet you're using, we don't know your rifle, and we do know that you're using imprecise Lee equipment. I'd also think you'd do better with something more along the lines of 414.
When you graduate to more precise equipment and start loading precision loads, you'll quickly learn how different bullets of the same caliber, weight, and general construction act differently. Little details like ogive and bearing surface can make a larger difference in your pressure gradients than you might imagine.

Answer 3

I won't comment on the weight, (don't load for the '06`),
but 4831 is a bit slow for a light bullet in a large
capacity case. - Won't hurt you though.

You worry me when you say "about 53 gr. of powder".
Loads can be sensitive and should be within 0.2 gr.
of the amount. (For your load, that's 4% accuracy.)
Buy a Lee powder scale, (They're pretty cheap),
before you hurt yourself.

Do check a Hogdon manual for a 'starting` load for
a jacketed bullet of that weight.
